I currently have a 1981 320i with a M10 1.8L engine, 5 speed trans. I bought a 1986 325E with a 2.7L engine as a parts car. I bought the car mainly for the larger motor.

I am putting the 2.7L, and the trans into my 320i...Has anyone ever done this before?...any advice?

Do i need to change the wiring harness as well?

All and any information much appreciated.
