Revision as of 09:07, 28 August 2019

Let's tune the BMW M52TUB25 engine from 170hp to M54B25 level (192hp).

Basic difference is that the M52TU engines use cable throttle with MS42 and M54s use drive-by-wire with MS43.

Here are both engine compared in known data:

Engine	Displacement	Bore x Stroke	Compression ratio	Power	Torque	RPM limit
M52TUB25	2494cm³	84mm x 75mm	10.5:1	170hp @ 5500rpm	245Nm @ 3500rpm	6500rpm
M54B25	2494cm³	84mm x 75mm	10.5:1	192hp @ 6000rpm	245Nm @ 3500rpm	6500rpm
