I think you may be right on Option 1 but I'm not certain. It appears a 328i with an intake manifold (stage 3), BBK, and LSD would be close to an e36 M3 and I would still have extra points for other things (especially if I lighten in up by at least 150 lbs). However, that is not a cheap set of upgrades. I would probably need to go with light weight seats to get the weight close.
