Bmw put the n54 in the 1m for a reason, its a collectors car and they wanted to give them the more powerfull and more tunable engine.
Now whether the m3 uses a worked n54 or n55, it doesnt matter, its a reworked engine, not stock so it doesnt mean anything.
Yeah totally, they built a whole engine around the idea of preventing people from modding it. Makes complete sense.
