    '89 M20 into an '87 chassis

    I'm replacing the engine in my car with one out of an '89 325is that was wrecked. What parts out of the '89 body am I going to need, if any?

    depends if you want to stick with your 87 cooling system or use the 89 later style, then you'd need the radiator, overflow tank, hoses. Is your 87 an I?

      It's an iS. I got all the info I needed from Jordan, I think. Everything's swappable, I'm just going to swap in the late-model cooling system since I have everything I need for it.

      EDIT: What about wiring? I read James's post in the other thread and need to know if any wiring will be different. The engine wiring harness out of the '89 is in one piece still, so let me know.

        if you use the 89 engine harness you'll have to rewire a couple wires. So I'd just stick your 87 harness on it and then you don't have that fuel injection harness plug that can become troublesome.

          Will do. Thanks.
