I posted this in the Turbo forum, but didn't get any replies and figured this might be the better forum anyway. I can get a JG throttle body that is I believe ~58mm.. It would be on my 94 si, stock motor and a 15g greddy turbo kit running 7 psi.. I just want to know if this would be a noticable upgrade. I can get it one cheap, but would rather not spend money on something that isn't going to make a difference right now.. So I wanted some opinions while i'm putting my motor back together. Thanks!
