Depends on what age the relative cars are; if they're both later 1988-on Motronic 1.3 cars, then the engines can be directly swapped over, otherwise, you'll probably need to swap the engine bay wiring looms.

Also, if fitting an M20B25, you should ideally also fit the disc rear brakes and beefier front struts that the 325i had.
