: question on engine change

12-16-2008, 09:44 PM
I just wondering if anyone knows if a motor from a '95 or a '90 525i would still fit the same as the one that is in my '90 525i? From looking at pics they look a little bit different. would there be many parts to change to get the other motors to fit:dunno:

Any of the e34 engines (and quite a few from some other models) will fit. There are differences in the location of the cooling system, brakes , and bracktes (welding required). If you are going to do the swap I'd get a donor car. That way you can swap anything you need to over.

Does your 90 have an M50? If so the only differnce between your engine and the 95 is vanos. If you do that swap you will need the engine, ecu and the engine wiring harness.

The M50 has a black plastic intake.
