Hello all, my name is chris and I am from Greece. I have a 1985 rx7 (streetporting fd motor turbo with carb) since 7 years. it's about 450hp and i have serious problem with my diff,which is from 92 mx-5 (1.8) . If you have any information about diff for this car please help!!!





I have already tried 3 diffs, but due to high power none of them seems to do the job.

 

I've heard alot about swapping in a Ford 8 or 9 inch rear end for handling alot of power but I don't have any experience with them. Someone on here should be able to comment on your situation. Do a search on this site on differentials. Good luck.
