I have a 1990 525i 5spd manual. I need a motor and I have found two cars that I can get the motor from. One is a 1989 535i(M30)automatic and the other is a 1991 525i(M50) automatic. Which of these is the easier/ better/ cheaper swap to do. I have a tranny from a 1993 325i cabriolet(M20 motor). Will it work w/ one of these motors. Will my drive shaft work?

The trans from the 325 will not fit anything other than an m20 motor.

As far as ease of swap, the M30 would be easier than the M50.
