i dont have an rx7 with a speedo... my gearing is all 4.78 anyway.

No, not even close, no fucking way, totally different box's

are you refering to the diff or the tranny in my post?

I was only told this. Never seen the Rx8 diff in person, so that's why i asked...???

Both ;) The carrier itself I BELIEVE is interchangeable but the pinions etc are not.

i have an 87' NA with a welded rear end. do you have any info on what happens to the mounts that make it bang around? thanks

welded diff is a no no...

But anyways, There are two diff mounts that bolt the rear of the diff to the body. Then there is a mount up front that bolts the nose of the diff to the sub-frame. This is most likely your problem. Search my name on here in the 2nd gen section and you'll see what I did to solve this problem.

thanks for the quick response. thats the only mount that i didnt buy from racing beat the other day. the other tech at my work said to check the u joints. could this also be a problem?


edit: could you also post a link to the post u were talking about i cannt find it

4.78!!!!!! Thank you for the info. I currently drive an '83 race car and auto-x/rally-x a bone-stock '87 TII. lots of useful info.

Incredible work man.
