Availability and price. Millions of cars produced and their worldwide availability guarantee the availability of spare parts. Parts, as well as complete gearboxes, are easily available at authorized service centers and on the secondary market.

Durability and reliability. BMW ZF / Getrag gearboxes have been successfully used for many years in both amateur and professional motorsport. They can transfer very high torque (some models 1000Nm+), while guaranteeing high reliability. They are ideal for SWAP projects with high power intended for daily use.

Speed and convenience. When using new generation ZF 8HP or Getrag DCT DKG automatic transmissions, we gain ultra-fast shift times (0.2 seconds).

FAQ

1. What gearbox adapter should be used to connect a BMW M50 S50 M52 S52 M54 S54 engine with a 6-speed BMW N54 gearbox?

No additional gearbox adapter is required to connect a BMW M50 S50 M52 S52 M54 S54 engine with a 6-speed manual gearbox from a BMW N54. Installation is practically P&P; the two upper holes of the GS6-53BZ gearbox need to be ground down for proper fitment – this procedure does not affect the centering of the engine and gearbox.

2. What starter motor should be used to connect a BMW M50 S50 M52 S52 M54 S54 engine with a 6-speed BMW N54 gearbox?

When using the custom PMC Motorsport BMW M50 S50 M52 S52 M54 S54 - GS6-53BZ N54 flywheel, the BMW OE starter motor from M50 S50 M52 S52 M54 S54 remains.

3. What clutch can I use with the PMC Motorsport BMW M50 S50 M52 S52 M54 S54 - GS6-53BZ N54 flywheel?

The PMC Motorsport BMW M50 S50 M52 S52 M54 S54 - GS6-53BZ N54 flywheel is designed for the M57N / M57N2 / N54 / B58 Sachs Performance 883082.001243 clutch pressure plate. Clutches from companies like ACT / Spec / Tanaci are often used with our kit (it is important that the custom clutch pressure plate also fits the BMW OE flywheel: BMW M57N / M57N2 / N54 / B58). For your gearbox, you should use a clutch disc with the appropriate spline, a dedicated release bearing kit, and a slave cylinder.
