alright, im going to build a turbo motor for my rx-7 but i have some questions before starting. if i say.. got 500 hp out of a 13B would the tranny hold up? how bout the rear diff?? would i be better off pullin out the whole IRS assembly and throwing in a straight axle ford rear end with ladder bars? what other parts of the car wouldnt be able to withstand this horse power?? also any turbo recemendations? thanks a lot guys

rear end and tranny will hold 500hp, tranny will last as long as you know how to drive. you'll need a pretty decent clutch setup. Only thing id consider swapping are the stock axles, they have 300m chromoly axles available thatll handle anything. the stock axles are good but at 500hp the launches have quite an effect on everything and those axles are probably the weakest link.
