I'm a newb here. I'm sure this topic has been covered time and time again, but here's the question anyway. If you have a link, I'd be glad to here it.
I'm building a chevy 350 motor with approx. 325-375 hp. I'm dropping it in a first gen rx7. I have most of my ideas planned out except the rearend. I doubt the original old one will hold up, and the newer rx's have the independent suspension, so where do i go? Is it just all custom, or is there some company that specializes in this stuff? Anyone? Anyone?

 

use the stock one. ive got a 406 torque monster in mine and its still good and ive been launching hard on this thing with slicks.

 

damn, did you change the gear or anything? just the small mazda rear end? It looks too small for that much power. Thanks

Anyone else?

 

same gear. some say its good to 500 horsepower and can withstand being taken into the 10's. If you really want to change it, grannys sells a 9" that will bolt into the FB. Im going that route after the stock rear takes a dump.
