One time I put a 86 320 motor into a 90 320, I had all kinds of problems,one of them was the fuel. It wouldn't work without the additional harness near the ECU not normally on a 90 320, but, on the 86. I added the wires to my 90, and the fuel problem was fixed. Don't know if this helps, but it would help more to know the year of the car and the year of the motor. You will have to change out the struts too, don't know if you planed on it already. e-mail me if I can help.
