I'am thinking about what compression ratio to go with on my build and want to make some serious power-per-psi and don't want to use race gas or go over 10-12psi. Could you run up to 10-12psi if tuned right with 93?

Sure, depends on the turbo, and good tuning. 10:1 will be nice on the streets higher compression helps the response.

hell yea man, no problem, the guy i actually bought my turbo kit off of (sc61, log mani, 3" dp etc.) made 320 hp at 10 psi tuned on crome. 100% stock gsr! (10.2:1 cr) If youre building it, there should be no problem running more boost, but you cannot slack on the EM System that you run. Its alll in the tune. Of course there are many naysayers out there, lecturing to keep it safe for a street car because of the risk of having a bad tank of gas etc, but do your research and you will be more than happy

ps. Im running JE Flat Tops yeilding 10.4:1 CR with my b16 head
