Ive gotten sick of fixing issues on my m42. Was going to boost but just not worth it. Engine is getting pulled this weekend. The car is an auto. I know i need a donor car. But do i want m50b25tu or non vanos. What would be easier to swap in. I plan on gettimg rid of the auto trans aswell for a manual. I was told its all plug and play. My car is a 95 318i. Would like to add power aswell with time. Any ideas on where to start? Any info helps.
