Read my post again. I did say that older ///M engines were based from standard engine but were extensively transformed. The S54 might be based on the M54 series, but the block was iron rather than aluminum, bored and stroked to 3.2L, new head and valve train with double vanos, individual throttles, etc... that to me that is an extensive tranformation.
However, the engine in the 1M is almost a straight carry over from the Z4 sdrive35is.
That is my point.
PS, don't quote the engine in the US spec E36 M3 as it wasn't a real M engine either...
