Simply change the flywheel or converter adapter, and the gearbox adapter remains the same.

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.

The starter remains OE Toyota 1JZ 2JZ (one mounting hole needs to be enlarged and a threaded insert included in the kit needs to be installed).

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

Two mounting holes of the ZF-310 ZF-320 Getrag 250 Getrag 420 gearbox should be ground down.
