I searched, but couldnt find anything, can the lsd itself transfer over (bolt on) or do you need the whole d15 tranny?

 

It will work.

 

the ring gear is a different bolt pattern, it will bolt into a ex/si tranny. You better have a 4.25 final drive in your trans, or get the lsd + lsd ring gear + countershaft.


make sure you shim or you'll be wishing that you did!
