It appears, from what I have seen in a few threads on here, that the N55 and N54 utilize the same HPFP.

Additionally, the use of the N54 engine in the 1M supposedly had to do with more development time being logged by BMW, when compared to the N55--there just wasn't enough time with the 1er's life cycle to get a fully tested N55 into the 1M.

My personal problem with the choice of the N54 is that numerous media outlets have confirmed that the engine is that found in the Z435is, which seems a bit dodgy to me. ///M engines have always had some sort of special component to them...I realize that the 1M will get the suspension bits, wider tires, and other ///M goodies, but I am definitely disappointed that there isn't anything else unique or special about the engine that will be in the 1M...

When first reports of the 1M were surfacing, our BMW insider SCOTT26 had stated that the 1M would get a revamped version of the N55, which would later become the "basis" of the engine to house the F20 M3. Unfortunately, that didn't happen....
