I don't think so...would be worth checking, but I don't think so.

What are you looking for from doing this? Throttle response? There are other ways.

Ama be blunt :) been there done that....ur cheapest power upgrade is an engine transplant.

Back to the M44 engine, a good service and aftermarket cams would direct you in that direction. But headwork and parts are always expensive, hence the first option; engine swap. And no the E30 diff is not a straight bolt on due to different diff housing and subframe design. But I can double check it for you.

well i noticed it has a different subframe...but i heard tht they can remove the inside parts of the LSD and put them in the frame of my diff...I dont know if tht is possible, but it would be a good upgrade for my car...and about the engine transplant, wat engine would fit in my car?

Yes you could remove the LSD from its housing into a new one...sorry I should've been clearer, I was referring to the whole assembly.



I'd throw an M52 in there alongside the LSD, but I'd fortify the chassis like crazy since the roadster is less than perfect in terms of stress transfer.
