Or maybe you are building a project with a Saab H engine (known from Saab 900, 9000, 9-3, and 9-5) in a rear-wheel drive car and looking for a durable 6-speed GS6-53DZ gearbox from a BMW 530d / 330d? In both cases, our adapter is a reliable solution. Gain a durable 6-speed BMW gearbox and easy access to spare parts.

The aluminum gearbox adapter plate was designed to simplify gearbox installation as much as possible, avoiding radical steps like cutting off the entire bellhousing – only the starter motor clearance needs to be prepared. The adapter requires a custom PMC Motorsport flywheel matched to the chosen gearbox (sold separately).

PMC Motorsport gearbox adapters are synonymous with precision and top quality. A design process based on 3D scanning and inspection using a measuring arm ensure a perfect fit. Production on modern CNC machines guarantees ideal engine-gearbox concentricity, which is crucial for powertrain durability.

Why choose a BMW gearbox?

Availability and price. Millions of cars produced worldwide guarantee easy access to spare parts. Both parts and complete gearboxes are readily available at official dealerships and on the secondary market.

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