Why Choose BMW Gearboxes?

Availability and price. Millions of BMW vehicles produced globally guarantee easy access to spare parts. Both parts and complete gearboxes are widely available at authorized service centers and on the secondary market.

Durability and reliability. BMW ZF / Getrag gearboxes have been successfully used in both amateur and professional motorsport for many years. They can handle very high torque (some models over 1000 Nm) while maintaining high reliability. They are ideal for engine swaps in high-performance projects for daily use.

Speed and convenience. New generation automatic gearboxes such as ZF 8HP or Getrag DCT DKG offer ultra-fast shifting times (as fast as 0.2 seconds), which significantly improves driving dynamics.

Installation Instructions

!! PMC Motorsport parts are intended for motorsport use on racetracks. Parts are to be installed by professionals using appropriate tools in suitable workshops !!!

You should use the flywheel / ring gear from the automatic version of the Toyota 1JZ 2JZ, along with one spacer (OE 32116-22020 4.5mm) between the engine block and the ring gear (not included in the kit).

The starter remains OE Toyota 1JZ 2JZ

Remove the bearing from the crankshaft hub (automatic version JZ) and replace it with a centering sleeve from the kit.

The bearing and clutch release fork remain from the existing gearbox. If you have a bearing with two height positions, use the 24mm position.
