Hi guys,
Can i put an engine from a later e34 (1995 2.5l petrol) into my 1989 2.0l?

Many thanks,
Mark.

Hi Mark,

How did you get on with the interior swap?

The engine will fit, you will need a 525i Engine, box, rad, all ancillaries, ecu and loom, also if its a 95 M50 you need the Keys and EWS im almost sure of. Its a fiddly job but it can be done.

Cheers

Ben

Hiya Ben,
Interior is crackin. I didn't change the doorcards yet tho due to laziness...
 
Sounds like a big job with the engine swap. Was half hoping it'd be a straight swap.
Once i'd start on the loom and ecu etc. i'm afraid i'd be left with a driveway ornament.

It is a bit of a pig, ive done similar jobs in E36's and i wouldnt be in mad rush to do it again unless i had plenty of time on my hands. If you do go ahead let me know if i can be of any help.

Cheers

You would need to change the ECU also (E34 had M50 engine whereas the E39 had the M52).
Sensors, etc possibly would need to be swapped also.
