I have a 94 camaro z28 m6. I'm currently running a sts rear turbo system with the t-67 upgrade. My engine is basically stock except for a cam. I wanted to reach to 600rwhp with my set-up. I was wondering what set-up I should go with a forged 355,383 or 396 stroker. Basically what shortblock?? Heads?? will easily get me at 600rwhp @12-15psi of boost

 

Forged 383. The extra cost, and less than ideal rod-ratio is the reason why you dont see many 396's. A 355 is only maybe 200$ less then a 383, so spend the money. Go all forged, and dont skimp on anything.

Run lower compression if you want 12-15 PSI, and Yes, 12-15 PSI, should pur you there.

Heads, I'd say LE3's, ported Trickflows, or AI heads.

Custom turbo cam from BRE, etc.

I actually dont know a whole lot about the STS rear systems, so youd probably be better off posting this in the forced induction forum. Im not sure how much boost you could get off of a T67 rear mounted set up.

And you definatly will want to intercool it.

 

Most of what he said was correct... but if you're trying to squeeze the most amount of power, then don't IC it. Spray alky for cooling. You can also run a small shot of nitrous which for an FI motor pretty much doubles it's shot number.

 

I'm going to be running both an intercooler and alky injection on my turbo setup.

 

imho with a turbo i would prolly go with a 355 and spin the hell out of it
