Greatness skips a generation edition

Correct the ND and NB are superior

Where's the link to the previous, this is not a good thread.

Daily reminder to grab seafoam when you change oil

>>28473343
Kek, nah

>>28473343
For what reason?
I use premium gas and keep my MAF clean. What would sea foam do for me?

>>28473411
Here's the back.

I know that NC. What size are the wheels?

>>28473434
Lmao

42°39'40.1"N 83°25'41.3"W

The superior NC.

>>28473251 (OP)
NA and NB are pretty much the same. It should be NA and ND.

>>28474142
that's an NC on the left in the OP pic.

i've not decided yet if i'll replace the radiator in my NB, and it could be 20+ years old for all i know.
but is an aftermarket radiator ok or is it another "OEM is vital" part?

>>28474333
Depends on the manufacturer, but generally speaking it should be fine. If there are reviews, check them, and make your own judgment.

>white stains on washed car
i hate car washing so fucking much

This is the dream. No forced induction.

>>28474411
Fucking love that build, so damn clean. Only thing to make it better would be an OE airbox.

>>28474333
When the black plastic end tanks go green, it's time to replace. They get brittle over time. Aftermarket should be fine.

how about this?
or is there a better option?
dunno about paying +£200 for OEM if OEM isn't vital for this job.

>vvt and 6spd trans swap my '90

No, just spend more and get an aluminum and never replace it again.

>Same aluminum koyo since 2005

>>28474542
Sell it then. Terrible to let that go to waste

Harness extended and brackets printed. It's going to happen boys. Just waiting on a new battery on the ancient laptop to arrive

>>28475621
this?
https://bofiracing.com/performance/cooling/radiators/skidnation-alloy-radiator-for-mazda-mx-5-nb/
that site has several more options, but this is the cheapest in-stock.

>>28475622
i might. i'll decide in a month.

>>28474586
very cute

>>28474489
>how about this?
Can't really pick any fault without actually holding it, but it seems fine and the reviews are reasonable, so I wouldn't be afraid of buying it.

>or is there a better option?
As >>28475621 said, an aluminium rad like you've found here >>28475711 is arguably the best option, but is pricey. If you're planning on keeping the car for longer than a decade or so, I'd get the aluminium, but with that being said, I'd flush the cooling system using the old rad first, then fit the new rad and fill it with pre-mixed coolant rather than tap water and concentrate. Tap water will eventually cause scale to build up on the inside of your fancy new radiator, and in roughly 10 or 15 years you'll probably see your cooling system start to lose its efficacy. I personally use Mazda's FL-22 coolant in my NA 'cause it's cheap as chips and you only need to change it every 10 years or so. MX5Parts sell it for around 15 quid, I think.

>>28476289
nice thanks. works for me.
i'll start researching the installation then.

Yeah please do not use tap water when filling your new radiator, you are just pissing away the robustness of any cooling system when you introduce scale.

Just get deionized water, it's like $3 a gallon.

>>28475641
based, pilled

miatas are so fucking faggoty I'd rather walk god damn

I've got a low mile NA8. I'm kinda bored with it. Completely stock.
Do I turbo it and maybe add coilovers/wider tires or buy another car?

>>28477605
Depends on how much effort you're willing to put in and how much you like the car. I'd personally just buy another car 'cause I'm lazy as fuck.

>>28477605
Get quality tires, an LSD and maybe refresh the suspension. I personally think Turbos are a nasty balancing act.

It's a Miata, unironically well balanced from the beginning.

>>28477605
ITB's.

Did you work on your Miata today? I rotated my tires. I’m too lazy to change my oil so I’ll do it tomorrow

>>28477776
i really hate the oil filter location.

>>28477863
kek theres no easy way to access it lol, even if you remove that faggot brace

>>28477896
>faggot brace
Took mine out and ground it down to remove all the sharp edges and make it a bit slimmer. Much better. Didn't know at the time that you could remove it.

>>28477776
Not with that giant heat wave
>It made my seat wave
Fuck 95% humidity while your at it

Too many things to do and no matter when I want to do it I will just sweat gallons. Gonna be a few months of collecting parts I guess

>>28477863
They make oil filter relocations.

It's like, a specific fix for this specific problem.

>>28477896
I have no problem getting to it on my 2 post lift

>>28474542
Had the same feeling a few times while rebuilding my engine and installing the turbo. It was just me worrying about something going catastrophically wrong, but I always double checked my work and nothing seriously bad ever happened. It's just a matter of getting over that initial hump and the enjoyment will come back

>>28476289
>>28476398
worth replacing the thermostat also?
mine seems fine, but some radiator replacement guides include a thermostat job.

>>28478678
If you have the cash and the know how change everything at the same time, since you’ll already have the fluid drained.

>>28478809
yeah that just occurred to me. don't want to have to drain it all over again if the thermo does need replacing later on.

>>28478804
lmao

>>28478804
Jesus Christ what a moron.

Took one of the young lads from work to Brands the other day, and he had a blast. He'd never driven a RWD car before, and he had this bad habit of mashing the throttle in the middle of the corner. Soon leaned his lesson by nearly spinning out, and by the end of the session he'd really got the hang of it. Think he's looking into getting a Miata, now.

I cant find my clutch alignment tool, i need to put the trans back in place.

can i get a link to a compatible one please

>>28475641
what are you doing with your TPS and air intake?
are you tunning it yourself?

Jesus Christ what a Chad

which one is more fun, the new Nissan Z or the ND3 Miata Roadster?

>>28479311
2002, tuning it myself hopefully. It's a pnp so all I have to do is run a vac line from the capped nipple on the manifold to the nipple on the back of the ECU and it's off to the races. I plan on ditching the MAF but then I lose my nice intake. Been looking for a J pipe in aluminum 2.5" with a tight bend so I don't cross the rad anymore.

I have a gm iat that I apparently do not need, but I am going to keep it anyways in case my stock one goes out.

I have too many projects to do with it in the meantime... more venting, delrin steering and diff bushings, new rear control arm+bushings... Just too goddamn hot and humid out there.

>>28479311
Oh and I wouldn't know about that tps, that's for na1.6 and it's not something I'm familiar with

>>28478804
This is unironically me. You cant tell from this angle but i swapped the engine and most of the drivetrain (cut down) from a ford ranger and the suspension from an Explorer. She wins shows. We show up with my wife’s 911 on the trailer, people always laugh.

>>28481275
>You cant tell from this angle but... swapped the suspension from an Explorer
Son, I could see that fuckin' pikachu MONSTER TRUCK suspension from a mile away with both eyes closed and both eyes tied behind my back

>>28481239
I need to figure out my intake. Using the stock 1990 intake with the GM IAT just tossed into the filter box, but I don't need the filter box anymore. Need to find a simple ass J pipe with a cone at the end...for cheap.

Thoughts on buying a cheap salvage title as a daily driver?

>>28481718
Can be fine. Salvage title just means the insurance company wrote it off which for a old miat can be due to basically any body damage.

Biggest issue with salvage titles is know what exactly gave it that title, how it was repaired, and insurance. Lot of insurance companies wont touch salvage titles or will give you absurd quotes.

>>28481787
>Lot of insurance companies wont touch salvage titles or will give you absurd quotes.
Why would you carry anything save liability on a salvage title?

>>28481242
i got a 1.8 swapped NA6, so i still have the 1.6 intake and tb. so would need to upgrade my tps.
or install a 1.8 intake.idk. i need to talk to a miata expert and figure this out.

t. currently dumping around 5k into a complete powertrain reseal and swap

>>28484731
I am doing everything BUT a reseal. Something is leaking, but only a few drops a week so I am not worried about it.

>Just ceramic coated the car

Now gotta wait 24 hrs. Has anyone applied vinyl stripes to their car? YouTube makes it look easy.

i've completed the radiator replacement job. here's a comparison of the new (left) and old (right) rads. the old one was so brittle that merely touching the slats would crumble it away.
i idled the engine for a little while with the heater on max. new thermo is also working, however the fan didn't spin. it's plugged in but i'm not sure why it didn't seem to be working.

>>28485057
u have two fans. did at least one of them start spinning when the thermostat opened? The other one only runs if the A/C is on or if the engine gets even hotter than what 1 fan can control and then the ECU kicks on the 2nd fan.
As far as I understand it.

>>28485160
one fan, no girly AC for me.
never spinned at any point. the thermo gauge moved though.

>>28485181
wtf. idk how your shitheap works then. good luck.

>>28485057
How long did you idle it? You need to put the heat in max but the blow on the lowest setting, so heat can build up.

I just flushed the coolant on my nc and it I had to burp the coolant a few times to get the air bubbles out, and get hot air at idle.

>>28485181
it did move past or to halfway on the gauge tho right? That's when it would start spinning i think.

>>28485222
its a hot day so it shot out hot air right away, but i kept idling it for 10 minutes anyway.
i'll try putting the blow on low setting and move it up.
>>28485224
moved to maybe 40%. i thought it might just be that the new radiator was doing a much better job of cooling.

>>28485228
it's possible it did not get hot enough to even turn on the fan. rev it while you're idling. get it to halfway. if it still doesn't turn on, I wouldn't push it, something's up.

You can also leave the cap off to burp, you will see the thermostat open by the water beginning to flow.

>>28485415
yeah I did that
>>28485234
going to idle it again tomorrow
cheers for advice lads, lack of fan action concerned me deeply

>>28484927
>applied vinyl stripes to their car
Installed some on the sides. Laid out the line with masking tape first, to make sure it went on level. Used water and a squeege to install it. Took a few hours but it turned out good.

>>28485534
Exactly what I plan on doing. I got the spinnywoosh standard Mazda in flat black. No candy in the package though. Your stripes look great, thanks for the confidence

>>28485534
The yellow with black top is really sexy. I was going to do this but I hated the hard top, convertible for life

>>28485605
Looks good with the black soft-top too. I wrapped the windscreen frame with vinyl initially, to see if I liked it. Ended up painting it black when the screen needed replacing.

>>28485804
Japan got the black frame on the '93 NA8 special.

Miatabros she rated us nearly a 10/10 across the board

>>28487656
Despite the "gay car" reputation women love the miata. It is friend shaped.

>>28487671
>the "gay car" reputation
wait what? Since when is miata known as the gay car?

>>28487674
Zoomer or bait? Call it.

>>28487678
I'm a millennial and never heard someone call my miata a gay car

>>28487689
You don't get out. Mine was gay from 2002 to about 2012, that's when the ND concepts started showing up.

>>28487695
It started earlier than that, unfortunately.
The men who call cute things gay are the gayest ones in the room; always more concerned about what other men think than just being secure in themselves.

>>28487674
/o/ is where the stalest memes go to die. Much like 'big truck, small dick' and 'all Dodge owners are niggers', they're meaningless twaddle by low IQ posters.

>>28487745
I have never seen a white man driving a Nissan Altima, though.

>>28485234
>>28485415
i idled it for 20 minutes straight this time, but the fan still doesn't come on.
things i've already tried:
>cap off to burp, can see the coolant bubbling right on the edge in the hole
>temp gauge moves to maybe 45% of the way, used to be 50% on the old radiator
>slowly moved the blower from low to maximum
>rev'd the engine several times
new radiator is only slightly warm to the touch in some areas.
i'm not sure what to do.

>>28488289
Are you sure the fan is getting power? Check the fuse and check the fan with a voltmeter. Are the radiator hoses warm? That will tell you if coolant is flowing

Anyone here have experience with Versa or Fab9 tuning? I'd really like to get rid of some of the rev hang on my Nd2, but I know tuning them is still kind of in its infancy

>>28488405
>Are the radiator hoses warm?
yes, i checked these and they are warm. i think the coolant is flowing ok.
the new radiator is much bigger than the one i pulled out, and it ate up the entire 5L bottle of FL22 i bought for it.
>Are you sure the fan is getting power? Check the fuse and check the fan with a voltmeter.
i don't have a voltmeter. :c

I just bought my first Miata on Friday, i love this car... (despite the power steering being basically gone and the AC being on its last leg)

>>28488472
Lovely color combination with the stripe.

>>28488410
go to harborfreight and get one then

>>28487656
>she

>>28488807
I've yet to see proof otherwise besides you guys being insecure she is 6'+

>>28488408
I got Fab9 with 7.8k rpm limit (ask for 7.8k tune and what gas (US or EU))
versa tunes you get with versatuner and you need it got fab9 tunes anyway
on both faster accelerator response
you can feel more umf on both maybe more on fab9 MAYBE
you should get tune
you don't need full versatune
but versatune tune is open and you could edit it if have full program (if you know engine jumbo mumbo)
don't waste time with popcorn on stock exhaust, zero effect
raised limiter alone worth it, for Nürburgring helped me a lot
and you can reach 100km/h on second gear.

>>28488937
Thanks chief

Do you guys ever hear a slight clunk or knock when the clutch engages? It's an ND. I often hear it when accelerating aggressively and shifting the gears quickly. The gentler I drop the clutch, the quieter the sound. I assume it's the whole powertrain coming into tension but I'm wondering if something is loose or something

>>28489072
I'm not 100% sure because the previous owner put them on the car, but I think they're TR Motorsport C1M.
https://www.tirerack.com/wheels/trmotorsport-c1m-bright-silver

>>28489812
Thanks for that, they're very nice. You've snagged quite a lovely little Roadster there.

There's a Mazdaspeed Miata down the street owned by a dude who's about to go into a nursing home. It's a 2004 in Titanium gray metallic. Looks to be in mostly good condition, except for the paint, which is completely fucked because no one around here has a garage. Otherwise, I'm thinking it was babied. 90k on the clock. How much should I offer for it? Would $7k be reasonable, not knowing anything else about the car?

>>28490510
offer a packet of these

Can someone post that pic where it says color a face on you miat?

Why haven't you joined a local Miata club yet?

Sure, mine is almost entirely retired boomers, but they drive like they've made peace with god.

I just take some place in the middle of the pack. Don't have to worry about hazards ahead as the lead will radio it in.

Always finding new, fun roads and driving at least every other weekend.

Meets are very little mingle time. 30 min top before we go over the route, select radio rolls and take off.

>>28490510
7k would be the steal of a lifetime for an MSM, they usually go for double that

Why are the gear ratios so fucked on automatics? The difference between 5th and 6th is like 250-500 rpm. You have to drop down two gears while cruising on the highway if you want to accelerate. I would've preferred a shorter 5th gear that puts the speedo at 3k rpm at 100km/hr and closer evenly spaced 2nd, 3rd and 4th.

>>28490917
I don't really see the point. I'm in the local FB groups so I can scoop up parts/ask for help but driving in a convoy with boomoids to some mid coffee chain to stand around talking about shit no one cares about sounds boring as fuck.

Whenever someone joins and posts their car there's a bunch of old farts that'll chime in crying that they've "ruined the car" because the poster has slightly lower springs and a sticker on the quarter glass.

who else here /plays with fire/

>hates when boomers shit on people for showing off their cars and interacting with the community
>shits on people for showing off their cars and interacting with the community
Not trying to start an argument, just taking the piss m8.
For real though, the guys that actually get out and drive around a bit are way more fun to be around than the miserable types who prowl around fb groups. Those old fucks are somehow even worse than the types that show up to boomer car meets just to sit by their car all day and glare at people. The internet's full of people that make it their life's goal to suck the fun out of anything they see, best just to ignore them ¯\_(ツ)_/¯

>>28491073
Presumably the ratios are optimised for emissions and mpg, why would you ever get an auto mx-5 though?

Picked up an '08 with 26k miles on it fellas. $16k out the door, how retarded am I?

>tfw you just 3.6 swapped your 5 speed

You've already committed anon, better start looking for a 6 speed to finish the job

>>28492340
Oh I have a 6 speed already. Gotta finish building my engine first though, not doing that work around the clutch and bell housing twice

>>28492346
Nice. I rebuilt my engine first and now I'm just waiting until I have some down time to get started on a diff rebuild. What did you end up getting your 6 speed for? I jewed some guy on fb marketplace out of one for $600 earlier this year

>>28488410
If your fan was turning on before you replaced the rad, then chances are the thermostat is opening and with the larger rad it's not getting hot enough for the fan to switch on.
I think OEM core size is like 16mm, so if it's a stock motor it'll probably never get hot enough to trigger the fan just idling. I have one of these skidnation radiators and I think it's kind of overkill for a street car.
Check if you have a 90ºC thermostat (stock temp afaik) and take it for a drive while keeping an eye on the temp gauge. As long as the engine warms up and the needle stays in the middle (or just short of the middle) you're probably fine.

>>28492401
i thought this might be the case but later today i'll be checking the car with a multimeter.
>I have one of these skidnation radiators and I think it's kind of overkill for a street car.
hah, but at £160 it was the cheapest aluminium rad i could find. i really want this car to last.
>Check if you have a 90ºC thermostat (stock temp afaik) and take it for a drive while keeping an eye on the temp gauge. As long as the engine warms up and the needle stays in the middle (or just short of the middle) you're probably fine.
i replaced it with an OEM from mx5parts.co.uk, but pic related it (left) looks different to the old one. i've noticed the needle goes to the middle much faster than previously.

>>28492374
Bought it at the same time as my JDM VVT (half a point higher compression than US NB2 + a squaretop intake manifold) engine for 3k total

>>28492425
Are you keeping it NA or adding power? How long did it take you to find a decent 3.6, or did you swap the ring and pinion yourself?

>>28492511
NA for now just to get it running and driving, but FI is not off the table. Likely going to suck it up and buy an MS3Pro PNP for the VVT control instead of the significantly cheaper VVTuner, which opens the door for tuning FI later. I got a 3.6 ring and pinion from Mazmart and paid a friend to build it along with a Torsen carrier (my old diff was open). While I'm open to learning the skill of setting differential pinion preload, I don't want it to be on this one. Maybe on the old diff I just took out.

>>28492425
I have an EUDM (or UK? idk I bought it from some dude on miataturbo.net) VVT with a squaretop.
It did make me mad the squaretop didn't have that many vac ports and I had to use a tee for the MSPNP vac line >:(

>>28492913
i do that and look like this

>>28492918
Yeah it's down one vs USDM since RHD (and I'm guessing euro LHD) never had cruise control as an option. I'm not using the vacuum port it has that goes to the return style fuel rail the JDM engine came with (mine is returnless) so I might get away with only one tee.

>>28492918
Everyone with a flat top drills and taps the upper mani for this exact reason, it is pretty easy.

>>28493087
thought about it. the dumb boomers on miata.net said not to do that, you need to use some super high precision tooling and press one in instead of tapping one with threads or some shit like the OEM vac ports are made. If tapping works I'll do that someday.

>>28492546
Definitely recommend going with the megasquirt, especially if you're even considering FI. I always wanted to eventually learn how to work on diffs, but my daily decided to make that decision for me when the rear end pinion bearing went bad last year. Honestly wasn't as bad as I was expecting once I got into it, but it took me way longer than I anticipated. The shim pack that came with the kit had a single 3 thousandths shim and every other was 10 or 15, so I had to rebuild the whole stack just to adjust it slightly. I could've bought another pack, but the only ones that would work were over $100 when every other size was $10-15. Overall kinda terrible experience, will do again (when the front bearing goes bad). New diff cover looks sick, I rate the experience 6/10.

>>28492546
megasquirt is great. consider beer money motorsports ECU. people keep raving about it. make sure it can do everything you want.

>>28493152
You can even drill it and jb weld a nipple on them.

Yeah I know how the boomers are on m.net. they just had a thread in off topic about one complaining about a hoarder. There is like 4 things on their back porch and one of them is that small Costco chest freezer.

>>28492913
Post shirt please. I've been looking for good miata shirts that arent overdesigned.

>>28493290
Sign up for Blipshift's email list, they do Miata shirts fairly often. I just wore this one today (they did have NA, NC, and ND versions as well)

I want a miata but I have a wife and large dog. What vehicle would fit the bill to take both of them out.

>>28493382

greem

Had my 96 M edition since February. Body is pretty smoked from rust / the p/o's kid hitting a deer. p/o aligned the cam gears wrong when doing TB / water pump job. Realigned the cams, buttoned it up. Started right up but the engine has either really loud lifters, or bottom end noise. Been looking for another 1.8 for 4 months but every deal I setup has fallen through. unsure whether to just give it up and sell / partout, or save up to do a swap.

Wish I had the balls to buy one of these, it'd be too out of pocket for me though. Seems fun

Have any of you driven both FR and MR roadsters? Any opinions? I really like MR2, MG F/TF, Lotus but they're expensive compared to MX-5, S2000, Z3 which I also like (except for electronic steering on the z3)

Lucky for you this car is so clean that fixing anything on it is worth it. Good luck and CUTE!

>>28493382
I'd choose an older BMW 3-Series as a relatively sporty four seater ragtop. Or if I had the funds, a 911 convertible

>>28494021
You should just remove and clean the lifters. Common problem and almost free to repair if you DIY it. Plenty of guides on YT. I did my NA6 in a day.

>>28488513
I think the fuse is fine, close to 0.01.
Unless I did the voltage check wrong, I think no volts are running to the fan.
So I guess I need to test relays now, but I don't have any alligator clips.

>>28493382
Try a Jaguar Xk convertible. Backseat isn't really big enough for a person, but a dog should fit just fine. Pretty fun V8 cruiser. Only real downside vs a Miata is no manual for the Jag.

Anyone here have up-close-and-personal experience with the inside of Miata transmissions? Specifically an ND would be great, but I'll take any insight. I'm trying to understand how the input shaft bearing is lubricated. I thought it would be lubricated by the transmission oil, but then I watched this video (of a 5 speed, so not an ND but still a Miata):

https://youtu.be/u8rTYlK8Q0g?t=126 [Embed]

Picrelated is a couple frames from the video. In the top frame, it's showing the front of the input shaft bearing which has the ball bearings exposed. The second frame shows the back of the input shaft bearing, and you can see it doesn't seem to be open to the rest of the transmission. Can anyone explain? Does the input shaft bearing have its own sealed lubricant?

Just took my 2020 ND on a road trip, taking the odometer from 14.9k to 18k in the course of 6 days, and while it held up great, towards the end of the trip, I noticed basically every symptom of early input shaft bearing wear, which is not an ordinary mode of failure AFAIK, not to mention it's a 2020 which is supposedly one of the years without systemic transmission issues, so I'm trying to figure out what could have gone wrong.

>>28496608
Bro fuck the nd especially the transmission, can't even hold up at stock power levels and I suspect it's because this shit heap was a joint venture with Stellantis.

>>28496818
>st*llantis
Fiata uses the NC transmission

>>28496818
>joint venture with Stellantis
How so? When did Mazda and Stellantis ever had any sort of partnership?

>>28496608
Maybe this video will give you some insight on how the transmission is setup: https://www.youtube.com/watch?v=A-w3D4g1P8I

>>28496940
Outstanding video, never knew there was such a closeup disassembly video of an ND transmission specifically, so will definitely bookmark it for future reference. It unfortunately doesn't have a closeup of the input shaft bearing (or countershaft bearing) though. But it does show they both sit nestled in specifically sized holes in the bell housing. So still leaves me wondering: how are they lubricated? If it's just the transmission fluid, how does it get into the bearing if they're closed on the side facing inward to the transmission? Or are both "faces" of the bearing open and I'm just seeing things wrong.

>>28496818
I don't even know for sure there's anything wrong with my transmission. All I know is it sounds a little different now. It still shifts like a dream, no grinds no nothing. Could just be that it has gone from pristine to not-pristine after my trip, could be that the fluid got broken down a bit. Or, in my worst nightmare, it could be that some metal flakes worked their way into the input shaft bearing and it's now damaged. That's why I'm trying to figure out if that scenario is even physically possible.

>>28496974
It's sealed with that clean landing in front of the bearing. The bearings are open, it gets lubed by transmission oil. It goes everywhere, it gets violent in the transmission case and oil goes everywhere.

>>28497021
>It's sealed with that clean landing in front of the bearing
You're talking about the cover that goes between the bearings and the bell housing right? So that creates a sealed area with the gears and the bearings inside and the oil in with it, and everything inside that zone is lubricated by transmission oil. But in my screenshot here >>28496608 the bearing doesn't appear to be open on the side facing the gears, and the input shaft bearing and countershaft bearing both sit in tailor-made holes in the transmission housing. So are you saying it actually is open? Or at least not a fluid-tight seal? Does it rely on transmission oil to just seep its way past the edges of the bearing and into the bearing?

If money isnt an issue z4 or miata

>>28497195
Z4 m40i if you want a larger, more planted and faster Miata.
Miata if you like small and light cars or a hardtop.
I would have gotten a Z4 myself if they had a hardtop variant (dont have a garage so its parked outside all year round). Sadly they did not.

>>28497195
You couldn't pay me to own a BMW ever again

>>28485160
>The other one only runs if the A/C is on or if the engine gets even hotter than what 1 fan can control and then the ECU kicks on the 2nd fan.
Different guy here but I think you just helped me out big time. I think my overheating problem >>28495601 is due to that fan not working. I just went out to test this, turned the AC on and the second fan didn't kick on.

>park miat for 6 months because it has a cold start misfire caused by low compression on cylinder 1 from an intake valve receding, never closing all the way (verified by both compression testing and by pulling the valve cover and checking valve clearance, there is none)

O that’s a problem. Glad to help

Anyone else here with an NB2 and front foglights, do you know where the socket/plug goes for the lights?
I have the fake vents and would like to replace them with lights. I know there's a separate bracket for lights too. Pic rel is what I'd be dealing with. And yes I can see a mudguard isn't properly fastened.

>>28498541
I don't know what your asking for but I am NB2 with dogs and replacing the bulb is a bitch so I went LED.

>>28498646
https://youtu.be/fvoW0mqtzas?t=552
Timestamp related - when he pulls out the old light, you can see the wiring harness. I'm wondering there the harness actually goes because I may have the sockets for it but not sure which.

>>28498813
I am lazy today and kinda hungover so I don't really feel like tearing down the front bumper, but you can see the harness and where it mounts in the repair manuals and wiring diagram on mellens.net

>>28498821
Seems a bit zoomed out.

Ok so what the fuck is the deal with the parking brake mechanism on the NA models?
My parking brake goes out of adjustment after a year, where one side gets all the force and the other side gets nothing. Super annoying having to adjust it so often

>>28498859
Could it be that you need to replace the cable ?

Was trying to replace the soft top today but it started sprinkling. I panicked to get the hard top back on by myself and slightly scratched the trunk...

My mom bought a new ND3 last weekend, so I bought her 2016 from her

Over time I've just shifted to all Mazda from Toyota

>>28499813
White ND's look great.
>>28499817
Do you have any of those super eurobeat stickers?

>>28499477
It feels fine for a few months and then I notice a decrease in clamping force. The cable would have stretched by a whole foot if it was it because I adjusted it quite a few times now

>>28499810
why the fuck did your mom buy the same car again

>>28500123
considering it's a woman and the car is automatic she probably needed the Bluetooth shit. I think the first gen ND had a shitty radio by normoid standards, either that or the nd is just a really good car.
>>28499810
tell your mom I said thanks for supporting team MAZDA

>>28498859
Very much a you problem. I adjusted the handbrake on my NA 4 years ago, and I've never needed to touch it. How long have you owned it? Some people aren't aware the the handbrake mechanism needs to be unscrewed when changing pads, and they'll just force the pistons in which damages the caliper, so maybe the a previous owner of your car has done just that?

>>28500176
both rear calipers were replaced by a shop, but they were refurbished and not new. Maybe they do have some internal damage

>>28499992
I need to make another batch of them pretty soon.

>>28500123
It was definitely a luxury purchase since she is retired now and the old car was perfectly good. The ND3 has a million small improvements, plus she got exactly what she wanted this time. She picked the old one up on a whim at a used car lot in 2018 because my dad and I were tired of fixing her piece of shit Mercedes. Took me 3 years to talk her into it. Since the 2016 is 9 years old with 90k miles and she's now 68 years old, the new car will last her and be trouble free until she's 80+. At that point she probably won't be able to get in and out of it anymore and will have to get a sedan if she's still healthy and driving.
Neither is automatic, they're both manual grand touring so the new one has lsd and bilsteins.

>>28500106
I have nb sport rear calipers on the 323 gtx and the self adjustment simply does not work, I have to adjust it a couple times a year. I fully rebuilt the calipers, I've looked at the geometry of everything in the cable system, used the book method for adjusting it, I've read up online, its just a problem some people have and I've never found a solution that made any difference. It could be that the stroke on my hand brake is different than the miatas but it works perfectly when adjusted so I don't think that's it.

I wish Polyphony would add the NB and NC to GT7. ;____;

>>28500472
>I need to make another batch of them pretty soon
I'd like that. There's a few Anons on /osg/ that would like a copy too.

i've got an 1.8l NB currently. love it, but the rust issues are becoming too much and because it's my daily (with frequent long distance drives) i want something a bit more comfy.
is the NC less of a money pit?
the 1.8l NC seems to be weaker (and heavier) than the 1.8l NC, does it feel noticeably slower too?
how do i gaslight myself into liking the look of the NC?

>>28502154
Miatas in general aren't a money pit, just get one that's already good to begin with and keep it waxoyl'd and maintained. Going from a rusty NB to an equally rusty NC isn't really gonna help you much money wise, and the same can be said for a nice NB and a nice NC. Get whatever you want.

>>28502154
>but the rust issues are becoming too much
pics?

>>28502187
but they don't get rusty frame rails, do they? and as i said, i'd like some more modern comfort too.
i've also just not been very lucky with this specific car when it comes to part failures.
>>28502194
don't have pics at hand but the frame rails need to be replaced in the next few years. there's also some minor rust on the wheel arch, but the frame rails are the biggest problem.

>>28502204
to add to that, it's become harder and harder to find nice NBs here

>>28502187
Do NCs have issues with rust? I thought it was just a NA NB thing

>>28502212
all jap cars have rust issues if they're old and if you live where the roads are salted or near the sea.
NC's "don't have issues" because theyre generally newer but I'm sure a few of them are showing their age now. Find a clean one and take care of it. Spray cavity wax or w/e on it.

>>28502204
NC's are *better*, obviously, owing to them being newer, but it's not as if rotten ones don't exist. They are more comfortable than NB's, though, being heavier and more softly sprung. My ex's mum has a very early one, and it was fine.

>>28502154
My NC is 17 years old, zero rust, but I don't drive it in the snow season. NC is so much fun to drive you don't care about how it looks. I think it's better than the ND except for the nose (ND better there by far). But the overall size is better on the NC and the rear is great .

So i finally got a better job. Currently i have a mazda 3 2024, im on year 1 of the lease so ive got 2 more to go. Does anyone know how mazda operates with their lease? Cause i would be trading it in for a nd3 miata in that case

>>28502100
FYI there is a built 1.6 on turbo Miata for $1500

>>28499992
>white
im so tired of these bland colors that are in overabundance on the streets. White, black, grey, etc. Mazda literally have the perfect red and people still opt for these basic colors

>>28502688
>red
What a special and unique color. I never see red vehicles.

>>28502789
disingenuous fag missing the point

Mazda needs to put as much passion in a green like they do with their soul red.

And no BRG unless the clear has flake. Sue me.

>>28503265
They should just bring back Sparkle Green Metallic and be done with it.

President Retard just announced new tariffs on Japan and Korea. Do I buy in on a new '25 miata now or hope he bitches out and I can buy the next production year whenever that might be

>>28503265
Agree on the BRG. The flat paint looks good on an NA with its more classic Bri'ish roadster inspired lines, but I don't love it on the curvier design of the NB. The metallic Emerald Mica on the NB fits it far better. I don't think BRG would fit very well on the ND for the same reason.

>>28503396
A reasonable position. I don't consider metallic green to be BRG but maybe that's what the ND needs. They did however get away with the non metallic Racing Orange on the 30ae and it matches the car's curves

>>28503273
I had an Astina/Lantis in Sparkle Green. Miss it a bit, but it was Mx-5 or Astina.

does Haynes ever get anything wrong?
pic rel shows the cooling fan relay to be the "rear most" or closest to firewall on the bank of three relays.
but in my Haynes manual the wiring diagram for the engine cooling fan and the listed colours of its four wires are actually going the relay on the other end of the bank in my car.
taking out a relay looks like a massive pain too, there's a metal bracket in the way which i've already unbolted but not coming off.

>>28503354
what trim 25 were u thinking? im eyeing the club but without the bbs package.

who else here /studded/

>>28503354
It's like the 5th time they announced new tariffs, each time they have a boost in sales. It's like it is all planned.

>>28504001
Yes. Their valve cover job.

Don't need for ITB but looks nice. Specs on engine?

>>28505057
JDM NB2 VVT 1.8 with a squaretop intake manifold (half a point higher compression than USDM, 10.5:1), no modifications except for using an OEM NB1 headgasket to better take advantage of the coolant reroute (and water neck delete), and a USDM NB2 exhaust manifold. Went for head studs anyway as I don't like reusing head bolts even when they're not torque to yield, and the ARP studs cost less than a set of OEM head bolts. Futureproofs it some too if I do decide to go turbo later. Also 6 speed and 3.6 swapping at the same time because I hate having money.

>>28505116
How much has this cost you so far?

>>28505126
Close to $5500 probably, but I'm doing everything myself (except for the head getting resurfaced at a machine shop and having the differential assembled) so at least I'm not paying anything more for labor on top of that. Oh and add about a grand when I get around to buying a megasquirt.

what are these two empty sockets for?

>>28505153
Nta but i am doing ms3pnp on my 02. Just printed a bracket for electricals today.

>>28506718
Gears 1-5 actually have almost identical overall ratios with 6MT+3.6 as my current 5MT+4.3 does, shouldn't change much actually. I just drove it for a week with 5MT+3.6 and while it certainly was slower to accelerate, getting the shorter ratios the 6 speed has will bring it back to normal, but with the 6th gear bolted on top it desperately needs on the highway.

>>28506722
Sounds awesome. You'll have to report back on how it feels once you have tested it.

>>28485057
If you haven't fixed this issue yet, it might be your thermo fan switch
https://www.youtube.com/watch?v=k3CFYWHSqMo

>>28506832
Speaking of which... where would that be on an NA 1.8 engine? There doesn't seem to be any electrical connectors attached to the thermostat housing

>>28506832
I considered that but I don't think the NB has one.

Add to that - I think I've isolated the issue to the radiator fan connector being faulty. 0v runs through it. I replaced the relay already and the fan fuse is fine according to multimeter.
I might have to buy a new connector for £9 and solder it onto the existing wire. There appears to be a clip-on for the connector, which in picrel is the black housing, but I think it'll likely be a solder job.

>>28506889
maybe it's on the rad

>>28506889
Top one is for the ECU (which controls the fan on NA8), left lower is for the gauge. NA6 has an additional one that grounds the radiator fan on the thermostat neck.
>>28506899
Correct, there is only one coolant temperature sensor for everything on the NB, on the rear water outlet.

>>28506916
If I removed that green connector and turned the car on to see if the fan starts spinning, would it be extremely painful (for me)

>>28506916
Hmm so if you put a NA neck on a NB could you still run one sensor and have an open port for whatever?

>>28487671
>women love the miata
First of all, that's not a woman.

Secondly, in my experience, women don't generally like small cars. They think they're "cute" which is not a compliment for a guy.

The reason to get a miata is that it's the most fun thing to drive.

>>28508276
I would assume so yeah. The port on the head and the thermostat housing have the same bolt pattern so they'd both bolt up. I'd probably recommend the FM reroute instead though, the block off plate and the custom rear thermostat housing both have threaded holes for the stock sensor and a 1/8" NPT sensor respectively, plus extra ones for turbo coolant feed lines if that's your thing.

>>28508299
Image presumably made by a man.

>>28487671
>>28508299
Doesnt really matter who likes ur Miata as long as /your/ girl likes it.

>>28508373
Yeah I would like the new FM reroute but don't really want to take the head off yet.

>>28508544
You don't have to remove the head? Unless you have an NB2 and you want to use the marginally better NB1 headgasket, there's no need to pull the head for access or anything to install it. The reroute is still an improvement on an NB2 with its original headgasket.

anything i should know before pulling the engine out of my miata?
the head gasket blew from overheating and the block is so warped thats its cheaper to buy a secondhand engine rather than go and get everything remachined.

>>28508724
assuming NA/NB, reseal the oil pan RTV and half moons, rear main seal, and rear main seal carrier RTV on the new engine before it goes in, you have to either pull the engine back out or drop the subframe to do it later if it leaks. also a good time to do the coolant reroute since cleaning the sealing surface for the water outlet on the back of the head is kind of a pain with the engine in the car (still doable though). pulling the transmission with the engine is also easier than dicking around with the bell housing bolts and then trying to stab the input shaft back in when going back together in the car, just paint marker around where the PPF bolts to the transmission so it's easy to just bolt it back up into the alignment it had before

>>28508574
Maybe but I am not going to half-ass a half assed job. They strangled the front cylinder so the coolant goes to the rear with the OEM layout. There is no way anyone will convince me that going NB2 reroute with NB2 gasket isn't the exact same as nb1 OEM with no reroute. You are cooking a cylinder regardless if it is #1 or #4.

>>28509578
Also get a real oil pressure regulator put on since it is a bitch to get to.

>>28510074
I mean, fair. That is the exact reason why I pulled my new engine's head at all instead of just resealing the outside.

Are any an/o/ns going to attend Miata at the Gap this year?

Well I have full exhaust, so it is naturally a bit on the loud side. It isn't drone nor loud it is just the constant pitch for 6 hours that does my ears in.

Hey guys. I posted this like 3 months ago but have been busy with other projects, now going back to this issue.
I accidentally scratched my crank removing the rear main seal.
I spent like an hour with 2k grit sandpaper taking the scratch down. Pic is what I'm left with.
While doing that I found another scratch that was put of sight the whole time. Ugh. No idea where that one came from. Pic in 2nd post.

How smooth do I need to polish this off so that's the rear main won't leak?
Completely or good enough?
I'm gonna go buy a Dremel and some polishing tips. I will also go back in by hand with a 1k sand paper.
Can I get some recommendations on what to use with the Dremel

The 2nd scratch that was out of view. I spent maybe 10 minutes on this one.
It's two parallel lines.

I picked up 600, and 1000 grit sandpaper and some green polishing compound

>>28511881
If you don't feel a lip anymore, send it.

>living in shame by owning an automatic ND2
>still love it dearly

>>28511881
i got filtered by teh front main seal and ia lmost got filtered by the rear main seal
fuck main seals.

>>28512050
Define lip. How smooth do I need to grind it down?
Any harm in flat spots?

>>28512267
why did you buy an auto? should i?

>>28512369
You shouldn't grind anything. Just get another crank. Use emery paper to get the ledge down without changing the face.

Just get another crank, best case scenario for you. Otherwise no matter what you do your hand will not machine it correctly

>>28512267
I wanna do one of those ZF swaps in mine after driving an auto yat. Its just so luxurious not having to worry about shiftan..

>>28512369
>Define lip
A raised edge that sits higher than the flat "bearing" surface

>How smooth do I need to grind it down?
Until you can't feel that lip

>Any harm in flat spots?
Not ideal, but so long as there's nothing higher than the bearing surface, it won't grenade the engine or anything.

>>28512871 is right in the sense that you shouldn't be grinding anything, use fine grit sandpaper to get the bevel down. Don't bother getting a crank yet; it's not ideal to be sanding any precision machined surface, but there's a non-0 chance that so long as there's no proud surfaces, you'll get away with it. Worse case is that it weeps some time later on down the line, but I wouldn't bother going nuclear and replacing the crank yet, not when this "free" fix might just work for you.

>>28512369
>>28512900
Oh, and this goes without saying, but don't sand anymore area than you have to, isolate your working area to as small as you possibly can. Don't start wearing down perfectly good areas of the crank if you can help it.

>>28512871
>just get another crank bro

I wish they would make a Miata that wasn't a convertible. Add more sound dampening, give back more trunk space since you don't need to store the top behind you. No more fake windows.

Guys, 1 year passed after I did regular service and changed oil/filters, but I haven’t reached recommended 20000km until next oil change, got like 4600km left. What’s the recommendation, can I drive around this summer for a few months?
I’ve checked my oil levels manually, oil looks above 50% between two holes on the oil check stick and the smell is OK. Is the 1 year oil filter change really recommended/mandatory or is it a merchant trick in order to syphon out my shekels?

>>28512937
Miata in question is ND 2018

>>28512937
It's not mandatory, but the reason they tell you annually is because your oil will naturally take on *some* moisture from the environment, and a car that doesn't get driven long enough to heat up the oil and burn off that water will experience marginally worse wear and tear than normal. I myself change annually if I don't hit 3,000 miles, but it's not going to grenade your engine if you yourself don't do it for a few more months, but I wouldn't leave it much longer than that.

>>28512955
thanks for the tip, kind anon!

>>28512900
Ok. In that case I got a small lip left. A lot of it is lower than the rest of the surface, is that okay to leave behind?
Also why would it grande the engine? This is for the rear main seal. At worst it'll leak a bit, no?

>>28513020
>A lot of it is lower than the rest of the surface, is that okay to leave behind?
Lower should be fine to leave, but I'd at least smooth off any roughness if there is any, just on the off chance the seal dips in and catches on it.

>Also why would it grande the engine? At worst it'll leak a bit, no?
I'm being somewhat facetious, worst case it will leak *a lot*, best case it doesn't leak at all.

cool, thanks.
im gonna hit it with 600 grit, then move to 1000, and 2000. if that gets it removed, i'll try the green polishing compound with a dremel

if that this leaks, then i'll have to remove the engine this winter and take the crank out and have a shop buff all the bearings.

90 minutes later this is the best I can do.
I skipped using a polishing compound as I have no safe way to prevent it from going inside the crank case.
If it leaks. It leaks.
It's dirt from the sandpaper. Need to spray it with brake clean. And then I got that 2nd scratch to work on. It's much lighter

Yeah that's gonna chew the seal up in less than a thousand miles. The seal is flexible and will 100% poke into that relief, you will gouge a ring in the seal asap.

>>28513270
Good luck, anon.

>>28513307
A thousand miles is better than no miles. What else can I do? Start with 200 grit. Is there a wider rear main sealer can put in there or position it so it's not on there?

I did some measurements and with the crank seal install tool I have it's going to push the rear over the ceiling surface back 11 and 1/2 mm which is just outside scratched area. This is the best I can do

Did my second-ever oil change. Whoever it was here that told me last year that the sticker wouldn't survive sitting on the oil filter... yeah you were right.

OP of the new /mg/ thread is a lazy cunt that hasn't provided a link~

I'm going to fucking send it. If it leaks a leaks, I'll have to take the crank out and get a machined during winter then

people actually buy miatas in autos? why?

>>28513490
Old people who struggle to use a clutch.

why is that your name

>>28513490
I have a bad knee and live in a high-density area for traffic. Shit sucks. I still am thinking about getting some shitbox in manual, but I daily my Miata.

>>28513748
you ever get friends or just random people being visibly disgusted once they find out its a auto?
