The engine is a tight fit and super heavy. The e30 M3 is known best for its awesome balance. That balance would be totally flushed down the toilet by swapping in a M5/M6 engine.
A better bet would be a late model M3 engine, which still might destory the balance of the car.
To have an M5/M6 motor in the E30? How much heavier is it? Would the plus out weigh the minus? Could the clutch handle it?
Or just change the rear diff? Or both?
hehe I guess no one paid attention to my post about engine weights. The S38 is actually slightly lighter than the S50! I was skeptical myself until someone posted a site that had supported the claim. Either way u go, you will upset the balance of the car by 80-100lbs. You can lose some weight by going with a bunch of lightweight front end parts and removing AC though.
