Additional Information

PMC Motorsport parts are intended for motorsport. For use on racing tracks.

Parts are intended for installation by professionals with knowledge of engine SWAPs and car modifications - in workshops and using tools appropriately adapted for this purpose.

The adapter installation manual contains only basic knowledge necessary for the physical connection of the engine with the gearbox outside the car body.

Depending on the car, additional modifications may occur, such as: fitting mounts, bushings, engine firewall, gearbox tunnel, driveshaft length, etc.

Our adapters are made from materials that are fully recyclable.

Why choose BMW gearboxes?

Availability and Price. Millions of cars produced and their global presence guarantee the availability of spare parts. Both individual parts and complete gearboxes are easily accessible at authorized service centers (ASO) 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 handle very high torque (some models 1000Nm+), while ensuring high reliability. They are ideal for SWAP projects in high-power builds intended for daily use.

ZF Friedrichshafen GS6-53BZ

The ZF Friedrichshafen GS6-53BZ 6-speed manual gearbox (S6-53BZ), due to its high durability (1000Nm+) and low price, is an ideal solution for cars prepared for motorsport. Female type spline: 32.5x35-26N

FAQ

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

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


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

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


3. Which 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 clutch pressure plate (Sachs Performance 883082.001243). Clutches from ACT / Spec / Tanaci are also very often used with our kit (it is important that the custom pressure plate also fits the BMW OE flywheel for: BMW M57N / M57N2 / N54 / B58). For your gearbox, you must use a clutch disc with the appropriate spline, a dedicated release bearing kit, and a slave cylinder.
