Hi guys,
So Im finishing up my M20B25 swap into my 325e and have some questions.
Some quick info,
Car: 1986 325E with M20B27
Donor engine is a M20B25 from a 1991 325i
The car currently has a C101 connector connected to the fuse box with 11 out of the 20 pins used.
The donor engine uses the same connector but has 16 out of 20 pins used.
My question is what is the pin configuration differences and changes needed to make this work?
Also does the current fuel system support the M20B25 engine or do fuel pumps need to be changed?
Thank you so much
