Anyone that had the N54 (myself included) would be able to tell you that these engines, while rated the same, were not the same in reality. N54 > N55 and now the N55 is getting long in the tooth.

Plus, generally people want something different (aka special) in an M car.

This was possible with the 1M because the internals started out stronger with the N54 to begin with, and then the M guys made more upgrades.

Similar with the S55 in the new M3/4 - significant changes to the original N55, which would be necessary for those levels of power.

My current N55, while a good engine, seems to run out of breath much sooner than my N54. No one wants that in an M2.

Just my $.02
When I was at the Autoweek 4 series test drive in August I had a BMW engineer tell me that the N54 was more powerful than the N55, however they can ring almost as much power from the N55. The made was done for fuel consumption. I'll let you know if my 335hp N55 435 fitted with a PPK us faster than my e92 N54 PPK in two weeks..
