A mate of mine bought a E46 316i with a blown engine.
He is having real trouble finding a M42 engine at reasonable cost(The valvetronic one).
Does does it take to fit a different engine in? Obviously exhaust and ECU will need to be swapped over, but are all the engine mounts, subframe ect the same?
Any difference between the 4 and 6 cylinder engines?
Is the auto box on the 316 the same as fitted to the other engines?
He is looking to by a complete car so would have all the related engine bits...
