I wish I could help you but most people want to under-drive the tranny, not over drive :D

You can get an e30 rear end (differential) It will bolt right on....

... btw, How is the SC? How much boost are you running? have you dynoed the car yet? I just installed mine (AA S/C).

Hydomen,

You're looking for a diff from a 1987 to 91 3 series. You'll have to fing out what your current diff is and then go from there. The diff should be in your owners manual.
