need motor for my 90 E34

[goodfolk]

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?

Not too sure about that??? I think you may need the tranny??? There is a 90 E34 being parted out here on this forum or you can contact westcoastautoparts.com and they should have the M20 you need.
