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 |
They are exactly the same, except for the 22hp difference in power.
