I need a motor for my 1990 E34 5spd manual. I haven't been able to find an M20 motor but I have found a 91 e34 M50 parts car thaht I can get the motor from. How much is involved with the e34 M20 to M50 swap. I know the obvious like wire harness and computer but can I use my drive shaft, tranny and rear end?
