Additional Information

Why choose a gearbox from BMW?

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 (ASO) and on the secondary market.

Strength 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 guaranteeing high reliability. They are ideal for SWAPs in high-power projects intended for daily use.

To install the flywheel, it is necessary to use the automatic version starter ring gear (Toyota OE: 32101-30090 | 32101-22050) and a spacer between the engine block and the ring gear (Toyota OE: 32116-22020, 4.5mm) (not included). The clutch fork must be mounted in the lower position of the release bearing (in the case of a two-position bearing)

FAQ

1. Which starter motor should be used with the PMC Motorsport Toyota JZ 1JZ 2JZ - BMW adapter?

For the adapter installation, use a Toyota JZ starter motor without the additional pinion shroud. Depending on the version of the Toyota JZ 1JZ 2JZ - BMW adapter you have, there are three installation methods:

a) Adapters produced until 2022 - the starter is mounted identically to the Original Equipment (OE).

b) Adapters produced from 2022 to 2025 - one of the starter mounting holes in the engine block must be enlarged. The hole should be drilled to a diameter of ∅12.9-13.2 mm (0.507"-0.520") to a depth of 22 mm (0.866"). Then, use the bushing from the AN 335-M10 kit and secure it with an ISO4762-M10x35 bolt.

c) Adapters produced from January 2025 - the lower mounting hole in the starter must be enlarged to ∅12-13 mm and the engine block must be tapped for M12x1.5.

2. Which ring gear should be used with the PMC Motorsport Toyota JZ 1JZ 2JZ - BMW flywheel?

When installing the PMC Motorsport Toyota JZ 1JZ 2JZ - BMW flywheel, use the starter ring gear (flywheel) from the automatic version of the Toyota 1JZ / 2JZ (OE number: 32101-30090 | 32101-22050) and one Toyota spacer (OE number: 32116-22020) with a thickness of 4.5 mm between the engine block and the ring gear.

3. Can I use the PMC Motorsport Toyota 1JZ 2JZ - BMW gearbox adapter for a ZF 8HP?

Yes, the PMC Motorsport gearbox adapter itself is universal and fits most BMW gearboxes available on the market (applies to adapters manufactured after 2022). If you wish to switch to a ZF 8HP automatic transmission, the standard flywheel must be replaced with an 8HP converter adapter (PMC Motorsport).

4. Which clutch can I use with the PMC Motorsport flywheel?

The Toyota 1JZ 2JZ - BMW ZF5 flywheel was designed for a clutch pressure plate from the BMW M57 / M57N / M57N2 / N54 / B58 / BMW E46 M3 / Sachs Performance 883082.001243. Very often, clutch kits from companies like ACT / Spec / Tanaci are used with our kit (it is important that the custom pressure plate also fits the BMW OE flywheel: BMW M57 / M57N / M57N2 / N54 / B58). For your specific gearbox, use a clutch disc with the appropriate spline, a dedicated release kit, and a slave cylinder.
