Thanks for this PDF mate - Quite interesting to see what BMW did different...

But a few things i've noticed so far...
1. For the M52TUB28, it says "The aluminium crankcase is 51lbs lighter than the cast iron block of the M52".... But I thought the M52 was aluminium, and the M50 was cast iron :confused
2. This keeps making reference to the "M52 in the Z3 Roadster"... I wasn't aware there was any difference from the M52 in the Z3 to the E36 :confused
3. I'm reading a graph for the power differences between the M54B25 vs M52B25, and its showing the M52 2.5l as having 168hp and the M54 2.5l as having 192hp :confused

This is an American document mate. Example, the M52 is aluminium in Europe, cast iron for the US market :hihi

i think thats a miprint, the m50 was cast iron! not m52! the m52 was the same in the z3 apart from cast iron liners, thats how i have read it. and yes the m52tu is a 168, remember this is the 323 version!
