hey hows it going, i just finished my turbo setup, 25 psi and 110 kmh rolling burnouts

with 265's in the back
so as the title says i'm looking for a bit of info for swapping to a taller final drive, i've read that all 6cy e34 and e32 share the same case, but i'm looking for 2.93 lsd or taller, i've found a couple in 325i e30's, i know the case wont fit but is it posible to change the crowngear set? and if so what other models/series can be used?
