i was wondering if it would be better to swap a 3rd gen mr2 turbo into a american 91 mr2 turbo....so then if u boost 15psi it would be way faster the if u were to boost on a 91 turbo.....please let me know ur opinion.

i would get the 3rd gen motor build it while it out of the car then put it in well depends on how fast you want to go but the 3rd gen is the way to go reguardless for a quick motor swap in my mind anyway
