Reply With QuoteThe motors are basically identical. I do know that the later usage of these engines saw a change to the Motronic control unit - so chances are that there is some electrical differences in the later engine.

How similar are the E34 M20s and the E30 M20s?
Other than the engine, what other similarities do these 2 serieses share with each other? Electricals? Tranny? Drivetrain?
All I know is that the older E34s have the same steering wheel fitment.

ETK shows 2 different part numbers for the E34 M20 (525i) and E30 M20 (325i/is) engines.....I know the difference(s) must be small, I'm assuming something like motor mount holes or similar??
Does anyone know for sure how the engines differ???
