I'm building an RB20DET for street use. I'm planning to reuse the stock internals and cams to keep costs down. Goal is around 400 bhp.
I've figured that I should do at least these
>new rings
>ACL bearings
>ARP head bolts
>Cometic head gasket
>adjustable cam gears
>valve springs
>valve stem seals
>oil sump enlargement
>add oil drain at the back of the head
Am I missing something?
Also, do I need a better oil pump or is OEM good enough?
