    M20B20 Motronic 1.3 Conversion

    What parts are needed to convert a Jetronic M20B20 (320i e30) to Motronic 1.3. I know the ecu and engine harness is needed but I canít find anywhere what other parts would be needed. The engine has been swapped into a 1987 325e so the car was originally running on motronic (I think).

    only the kids e30s
    I would imagine all the stuff for just a normal e to I swap. engine, engine harness, ecu, afm, injectors, and probably have to do some little jumpers in the cabin at the c104 like for the e to I swap. I was googling the other day because we did an e to I swap and I had found someone went through the same swap you are doing a number of years ago and I think they were told just act like its an e to I swap and wire that way
    no e30s of my own, but I am financing two for my kids
