B58 engine reliability BMW engineers were able to resolve the main issues with the engines that preceded the B58, including: Updating the fuel system Modernizing the cylinder head They fixed issues with the particulate filters A fresh design for the timing chain All these inline 6 BMW engines are excellent, but the N54 definitely deserves respect for its accomplishments based on the era the engine was released (and what it still accomplishes to this day). Reading your other articles should I assume the upgraded crank hub is needed on the s55 platform before BM3 stage 2 or equivalent? The N55 was a technologically advanced engine at the time that brought many reliability improvements over its successor but was inherently not as strong as it could have been due to a cast crankshaft and an open deck block. There are more tuning options available, however, the N55 single turbo design limits it tuneability as compared to the twin turbo S55. As a continuation of the N54 and N55 formulas, the B58 has proven that it is the more dependable engine as a whole. Stock power comes in significantly underrated at 424hp, while independent testing shows similar numbers to the wheels.

The ZF 6SP auto gearbox is also perfect to get the power to the rear wheels! Hardly worth mentioning as it is only a handful. Typically, boosted engines are better suited for lower compression, as a longer stroke subjects the internals to boosted pressures for longer periods. (cold start is just supposed to head up the catalytic filter in the downpipe, so thats why its commonly removed after catless downpipe installation.)e. Compared to the two former engines the N55 has been on the road longer, allowing for additional time for tuning developments.
