You can do the head swap to a 325i (885) head but you will need wiring harness an ecu intake manifold an what not its easier to use a 325i then a 325e cause you will have everything already an youll only need just the bottom end out of a 325e but you can turbo a 325i as it is but you will only run low boost 8psi is what i think is safe the 2.7 head swap motor can take up to 15psi of boost cause the compression is lower you can look on for more info alot of them over there are running m20 boosted
