I have a '94 e36 316i coupe with the m43 1596cc 8v, which uses a timing chain.

My question is can a 16v head from the m42 or m44 be fitted to my m43 block?

Now I have searched the forum other and found quite a few related threads with people asking the same or similar things, but none with a simple definitive answer.

Im sure it can be done, but what I want to know is, is there a huge amount of modification required, has anyone done it, and what parts will I need from the m42 (inlet manifold, timing chain and sprockets etc.), and will i need to change the engine loom and ecu?

Oh and it would probably be just as easy to fit the 1.8/1.9 engine, but I want to stay with the 1.6, its just easier on insurance, car tax and petrol.

Any help is appreciated...
