You are all discussing about the same part numbers between 335is and Z4 35is... and with this as fact you say the same engine is in the 1M. BUT... we still don't have part numbers from the 1M N54 engine!
So this is senseless to talk about.. lets wait until the 1M engine specs and graphics are only also to compare with the Z4 35is.
In my opinion I really doubt that M did not change any Hardware parts of the engine....
