Adapter for integrating BMW M50, M52, M54, S50, S52, S54 engines with a ZF GS6-53BZ 6-speed manual gearbox, originally from BMW N54 models such as the 135i, 335i, and 535i. The adapter includes a flywheel weighing 7150g (15.76lb), which is 60% lighter than the original, enhancing engine response.

Installation Guidelines:

The installation process is largely plug-and-play; however, modification of the two upper holes on the GS6-53BZ gearbox is required for proper fitment. This adjustment does not impact the alignment between the engine and gearbox. The BMW OE starter motor from M50, S50, M52, S52, M54, and S54 engines remains compatible. The adapter is designed to work with M57N/M57N2/N54/B58 Sachs Performance clutch pressure plates. Clutches from manufacturers such as ACT, Spec, and Tanaci can be utilized with this kit, provided they are compatible with the BMW OE flywheel.
