The engines were fitted to quite a wide cross section of BMW's, and M54 engines are great to work on and respond particularly well to camshaft upgrades and mapping. Notable alterations were an increase in displacement (bore and stroke adjustments) on some models which affected power output but they share similar parts and had a common 6500rpm rev limit.Īs with any tuning project, your mods will add a percentage power gain, so you'll see better gains on the larger displacements.Ģ,171 cc 168 hp rpm 155 lbft rpm 2000–2006Ģ,494 cc 189 hp rpm 181 lbft rpm 2000–2006Ģ,979 cc 228 hp rpm 221 lbft rpm 2000–2006ģ,246 cc 343 hp rpm 269 lbft rpm 2000–2008 This engine topped ward's 10 best engines list and is regarded as one of the strongest engines BMW have made, thanks to its cast iron internals. The M54 gained much respect and won accolades in its early life.

The power of these engines was deliberately kept low to ensure the reliability of the engine and push some of BMW's other engines, which thankfully means there is a lot of headroom for tuning up these very solid and well-designed engine blocks. With the right mods you should see gains of around 10-15% without getting too extreme and spending a lot of money. The M54 came with a displacement of 2.2, 2.5 and 3.0 with power ranging from 170-280hp. It was a silky smooth straight 6 and didn't change much during its 6 year lifespan. The S54 performance version of this engine was fitted to the Z3 and Z4 cars.

The M54 was produced between 20, and replaced the N52. Guide to performance tuning the M54 engine from BMW (M54B30, M54B25, M54B22) History, Power & Specs of the M54 Engine
