Race Stage 1 Toyota 1JZ 2JZ - 6-speed manual BMW M57n GS6-53DZ HGU HGK - 240mm / 9.45"

PMC Motorsport Race Stage 1 – clutch kit Toyota JZ 1JZ 2JZ – 6-speed manual BMW M57N2 ZF GS6-53DZ HGU HGK 325d 330d – 240 mm / 9.45" – Sachs Performance 883082.001243 – max. 800 Nm / 590 lb⋅ft

Complete Race Stage 1 clutch kit enabling the connection (swap / conversion) of the Toyota JZ 1JZ 2JZ engine with the manual 6-speed ZF GS6-53DZ HGU / HGK gearbox used in BMW with the M57N2 engine (E9x 325d / 330d). The kit includes a gearbox adapter plate, custom PMC Motorsport flywheel, reinforced Sachs Performance 883082.001243 clutch pressure plate (non-self-adjusting), and a PMC 240 mm sintered clutch disc with a 32.5x35-26N spline. The maximum torque capacity of the kit is 800 Nm (590 lb⋅ft). Due to its characteristics, the kit is intended for motorsport – drift, track, and high-power turbo builds.

Are you planning an engine swap of the Toyota JZ 1JZ 2JZ into your BMW (E30, E36, E46, E34, E39, E90, E91, E92, E60, E61, E81, E82, E87)? Our adapter plate is a reliable solution. Swap the automatic transmission for a BMW manual gearbox and unlock new possibilities.

PMC Motorsport adapters are not only for converting automatic transmissions to manuals in vehicles with the Toyota JZ 1JZ 2JZ engine, but also provide support for completing a JZ swap in BMW and other vehicles, such as Nissan (S13, S14, S15, PS13) or Mazda RX-7 / RX-8.

The aluminum gearbox adapter plate is designed to simplify gearbox installation as much as possible, avoiding radical steps like cutting off the entire bellhousing – only preparing the starter motor clearance is required. Custom flywheels dedicated to PMC Motorsport adapters are made of aluminum with a replaceable steel friction surface, inspected and balanced before shipment. Flywheel designed for a 240 mm (GS5-39DZ / GS6-53DZ / BZ BMW OE) pressure plate. Flywheel weight: 5.4 kg (11.9 lbs), adapter thickness: 20 mm (0.78").

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.

Additional information

Installation instructions

For flywheel installation, it is necessary to use the automatic transmission starter ring gear (flexplate) Toyota OE 32101-30090 or 32101-22050 and a 4.5 mm spacer between the engine block and flexplate, Toyota OE 32116-22020 (not included in the kit). Bolt the flywheel to the crankshaft using the included bolts tightened to 72 Nm (53.1 lb⋅ft) with threadlocker. Install the clutch release fork (dedicated to your gearbox) on the lower release bearing position (for a 2-position bearing). A Toyota JZ starter motor without an additional pinion cover must be used for mounting – details in the FAQ section.

Frequently Asked Questions

Which engines does this kit fit?

For Toyota JZ family engines: 1JZ (1JZ-FSE, 1JZ-GE, 1JZ-GTE) and 2JZ (2JZ-FSE, 2JZ-GE, 2JZ-GTE), in VVT-i and non VVT-i versions.

Which gearboxes fit the kit?

For the 6-speed manual ZF GS6-53DZ gearbox from BMW with M57N2 engine (E90 / E91 / E92 325d and 330d) in HGU (THGU) and HGK (THGK) versions, and for the xDrive version GS6X53DZ HGW (THGW) and HGL (THGL).

Do I need to cut the gearbox bellhousing?

No. The adapter was designed to avoid cutting the bellhousing – you only need to prepare the clearance hole for the starter motor.

Which additional parts do I need to buy for installation?

Automatic transmission starter ring gear (flexplate) Toyota 1JZ / 2JZ, OE 32101-30090 or 32101-22050, and one 4.5 mm spacer between the engine block and flexplate, Toyota OE 32116-22020. You also need a release bearing, clutch release fork, and slave cylinder dedicated to your specific gearbox, as well as a Toyota JZ starter motor (see question below). These parts are not included in the kit.

Which clutch is included in the kit?

A reinforced Sachs Performance 883082.001243 (88 308 200 1243) pressure plate with a 240 mm (9.45") diameter, non-self-adjusting, and a PMC 240 mm sintered clutch disc with 32.5x35-26N splines (26 teeth) for the ZF GS6-53DZ gearbox.

What torque capacity does the Race Stage 1 kit hold?

The maximum torque capacity of the kit is 800 Nm (590 lb⋅ft).

Is this kit suitable for a daily driver?

The Race Stage 1 kit with a sintered disc is primarily intended for motorsport – the clutch operates harder and less smoothly than an organic disc. For a vehicle used mainly as a daily driver, we recommend the Stage 1 kit with a Sachs XTend clutch.

Can I use a different clutch?

Yes. The PMC Motorsport flywheel is designed for a 240 mm BMW OE type pressure plate – from BMW M57 / M57N / M57N2 (including stock GS6-53DZ pressure plate) / N54 / B58 / E46 M3 or Sachs Performance 883082.001243. ACT / Spec / Tanaci clutches are also often used – a non-standard pressure plate must fit under the BMW OE (M57 / M57N / M57N2 / N54 / B58) flywheel pattern.

Which starter motor should be used?

Toyota JZ starter motor without an additional pinion cover. The mounting method depends on the adapter version:

a) adapters produced up to 2022 – starter motor installs 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 drilled out to ∅12.9–13.2 mm (0.507"–0.520") to a depth of 22 mm (0.866"), then use the sleeve from the AN 335-M10 kit and bolt with ISO 4762-M10x35 bolt;

c) adapters manufactured from January 2025 – the lower mounting hole in the starter motor must be enlarged to ∅12–13 mm diameter and the engine block tapped to M12x1.5.

Does the adapter also fit the ZF 8HP automatic transmission?

Yes. The PMC Motorsport gearbox adapter plate itself is universal and fits most BMW gearboxes (applies to adapters produced after 2022). When converting to a ZF 8HP automatic transmission, the standard flywheel must be replaced with a PMC Motorsport 8HP torque converter adapter.

What is included in the kit?

Aluminum gearbox adapter plate with mounting bolts, PMC Motorsport custom flywheel with replaceable steel friction surface (5.4 kg / 11.9 lbs), crankshaft bolts, clutch pressure plate mounting bolts, ball pin – BMW OE 21 51 1 223 328 replacement – Sachs Performance 883082.001243 clutch pressure plate, and PMC 240 mm 32.5x35-26N sintered clutch disc.

Can I buy only the adapter or only the flywheel?

Yes. Every component of the kit is available separately – including the adapter plate itself with the flywheel, without the clutch.

Does the price include customs duty for shipments outside the European Union?

No. The product price and shipping estimate do not include customs duties or additional fees that may apply in the recipient's country.

Can I buy with 0% VAT?

Yes, if you are a B2B customer outside Poland with an active EU VAT number (verification in the VIES system) or ordering with shipping outside the EU.

Are the included instructions sufficient for installation?

The instructions describe connecting the engine to the gearbox outside the car body. Depending on the vehicle, additional modifications may be required: mounts, bushings, firewall, gearbox tunnel, driveshaft length. We recommend installation by professionals.

It is worth remembering that a lightweight rigid flywheel provides uncompromising throttle response at the expense of eliminating factory damping elements. This translates into a more direct drivetrain operation, which may result in a natural increase in the audibility of gearbox mechanisms. This is a desirable characteristic in sports vehicles, resulting from a rigid connection between the engine and the drive.
