My E30 M50 Swap with pictures

Should have cleaned the motor before you dropped it in! :)

Oh thats what the little dealie bob is for i always thought it was like a battery fuse or something. Hmmm.

The missing connector is probably for the e36 reverse light. Disregard it. The only thing you need to connect off that part of the harness is the one O2 sensor.

The dealie by the fusebox that you can't identify is an aux fuse panel. For adding an alarm or other accessory.

Great progress man. Good luck with the wiring!

hmm why is it a pain to insert multiple pics..

This is my first motorswap and im sure there is going to be alot of surprises. I have a 1987 325e with 210k miles. I just got a 92 m50 non vanos engine with 132k from P.A.





I just dropped the motor in without the transmission to see how things were going to fit and line up.






One of the plugs were cut off and im not sure what its for, possibly another 02 or monitor sensor? It branches off the wiring harness where the plug is for the transmission.


Ive always wanted to know whats this for..


So i got the motor sitting in there, i dropped the motor and transmission as one, it was obviously a tight fit. Hopefully i dont have to take it out until this winter...

Im going to start the wiring today and hook up a few odd and ends to see if i can get it to crank over, and maybe see it firing too. I will update soon with more pictures, and hopefully with not too many questions, will see.
