mig8788 Posted September 17, 2012 Report Share Posted September 17, 2012 I think you will have know problem with running a turbo and making good power. I have a 75mm i plan on running. My buddy just did a ls1 swap in his firebird with a 75mm turbo with e85 and made 575hp on stock motor. Good luck with the build makes we me want to get mine done.
