Title: another m44 question
Post by: brenters on July 07, 2008, 08:40:51 PM

I have an e30 '84 318i and I was going to put in the M42 engine until I saw all the threads on here about the M44 engine.  I'm  now going to go with the M44 and would like to double check everything I am going to need to do the swap.  Based on the other threads, let me see if I got this right.  

I'll need: any M44 engine (96-99, they're all the same, 318i or Z3)
             M42 wiring harness
             M42 ECU

Is that the way to go?  I was reading about how the M44 computer has the EWS immobilizer stuff in it so I should stay with the M42 computer and get it reprogrammed for the 1.9L displacement.  Is it as simple as taking it to a dealership and they know what to do?

Also, what other little things will I need, like are the engine mount brackets the same?  Different pulleys for the front end?

If anyone can give me a comprehensive idea of what all I need to make this happen I would greatly appreciate it

Well looking at the current intake swap thread, you'll need an e30 intake as the M44 will be too tall (although I thought it was the other way around) and an e30 oil pan.

I think the M44 has different sensors, so I am not sure simply using an m42 computer will do it.

Maybe MarkD or conforti can do a custom chip for you if you can get the connections figured out. I am sure a dealer will not touch it.

There has been some threads on this before. Try the search.
