Design, development and variant notes
The M54 has an aluminium block with iron liners, double-VANOS, DISA intake, electronic throttle and Siemens MS43 management. The North American M54B30 ZHP version used revised camshafts and calibration.
The S54 is more closely developed from the S50 than the M54 and has an iron block. Wikipedia identifies MSS54 management, with MSS70 in the later Z4 M; S54B32HP is the higher-output M3 CSL version.

Additional technical and variant notes
The North American M54B30 ZHP specification is listed at 175 kW and 301 N⋅m, with revised camshafts and management. The article states a 6,800 rpm redline for that version.
The M3 CSL's S54B32HP uses a carbon-fibre intake, revised camshafts and a MAP sensor in place of the regular S54's MAF sensor. The article lists 265 kW and 370 N⋅m for the CSL application.
Further specifications from the cited article
Additional facts are adapted from this Wikipedia revision by Wikipedia contributors, under CC BY-SA 4.0.
The article gives a 6,500 rpm redline for the described M54 and 8,000 rpm for the S54. The S54 has a cast-iron block, while the M54 uses aluminium; these figures should not be transferred to the ZHP specification without checking its version.
