well they say the stock rear end is good for around 300hp. my goal is to have around 300-350 RWHP, so i have some time. they also say the V8 is better for the rear end then the rotory. because, the rotors make all the power up high in the revs, you have to do high rpm clutch drops, the 5.0 has power on demand, meaning i dont need to rev to 6k or more. but i completely see what your saying. granny's speed shop is now selling kits that adapts the 8.8 rear end to the rx-7. i will prolly enventually get one of those.
a great website for others to see Rx-7's with other types of engines is www.torquecentral.com awesome site.
