it gets flack mainly for being in an obscure car that didn't really compete with similar cars at it's price point. it also gets a bad rap for the owners complete lack of awareness on how to treat a high performance turbo car. lots stuck a JB4 on it, cranked it to map 6 and then cried when they toasted it. I make about 500hp from mine on Z1 turbos and it's been fantastic. I'll be adding a higher flow HPFP and ethanol flex kit soon and shoot for 700hp. Say what you want but the ease of making power on these is second only to a few engines and it's the best at it's current used market price in q50s and q60s.
