323i m-50 conversion

I have an 81 323i and a wrecked 95 325i, I'm going to swap the motor and electrical system, and I was thinking I'd run an early e30 five speed (the one with a 0.81:1 fifth gear) and an e34 rear differential (3.25:1 limited slip), and was wondering if anyone has done a full engine/electrical swap before?

Hey have you started your conversion yet ?

Not yet, I have to build a garage first.
