Sure, the core is an N54 engine, but anyone saying that his/her 135i N54 is identical, is in some major denial. Clearly the N54 going on the 1M was tweaked to better suit the task at hand, which is powering a car worthy of the letter ///M

Having been in the engine compartment, I am not sure how the intake is different. And, I don't believe BMW has used this trans in any other 1-series.
But, otherwise agree.
