Title: M42/44 Compatibility
Post by: m318i on October 10, 2008, 02:41:40 PM

Hey Everyone,

I own a 92 318i. I had some engine issues on my car so I decided for the time being it would be easier to swap the engine out for another then doing a headgasket job and machine work for my current motor. I purchased a 89 m42 engine to replace mine so I knew I had to replace the intake and oil pan with mine. I purchased a what I found out now M44 intake manifold just to put on the 89 motor and drop in as a whole. So here are my questions:

From what I'm seeing there is just a electrical plug on the bottom of the 44 intake for the torq flap while the 42 has a vacuum flap that then connects to a solenoid with the same plug I think. In theory I believe that they are both just solenoids so I should just be able to plug the plug in and and it should work. SO.....

Does anyone know if the 44 is just a electric solenoid or is there some vacuum source going into that black box?

Also, very important
Does anyone have a E36 M42 and M44 vacuum diagram?

THANK YOU!
