Complete Stage 1 clutch kit enabling the mating (swap / conversion) of the Toyota JZ 1JZ 2JZ engine with the ZF S5D-280Z (ZF-5) 5-speed manual gearbox used in BMW M47 diesel models (E46 318d / 320d, E39 520d). The kit includes a gearbox adapter plate, custom PMC Motorsport flywheel, and a Sachs XTend 3000 951 877 (BMW M57) clutch kit – self-adjusting clutch pressure plate (SAC), organic clutch disc with 28x35-10N spline, and clutch release bearing. The maximum torque capacity of the kit is 650 Nm (479 lb⋅ft). Paired with the S5D-280Z gearbox, the Stage 1 kit is an ideal solution for daily-driven cars, drifting, and amateur as well as professional motorsport.
Planning an engine swap with a 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. Replace an automatic transmission with a BMW manual gearbox and unlock new possibilities.
PMC Motorsport adapters not only enable converting automatic transmissions to manual in vehicles powered by the Toyota JZ 1JZ 2JZ engine, but also facilitate swapping the JZ engine into BMW chassis and other platforms such as Nissan (S13, S14, S15, PS13) or Mazda RX-7 / RX-8.
Aluminum gearbox adapter plate engineered to simplify transmission installation as much as possible, avoiding radical modifications such as cutting off the entire bellhousing – only an opening for the starter motor needs to be prepared.

PMC Motorsport components are designed for motorsport and racetrack use.
Parts intended for installation by qualified professionals experienced in engine swaps and automotive conversions – in proper workshop environments with suitable equipment.
The adapter installation manual provides only the basic information required for the physical mating of the engine and transmission outside the vehicle body.
Depending on your specific vehicle, additional modifications may be required, such as custom engine mounts, poly/rubber mounts, firewall clearance, transmission tunnel modification, propshaft length adjustment, etc.
We manufacture our adapters from 100% recyclable materials.
Installation of the flywheel requires the automatic transmission ring gear / flexplate Toyota OE 32101-30090 or 32101-22050 and a 4.5 mm spacer washer between the engine block and flexplate, Toyota OE 32116-22020 (not included). Bolt the flywheel to the crankshaft using the supplied bolts, torqued to 72 Nm (53.1 lb⋅ft) using threadlocker. Mount the clutch fork on the lower release bearing position (for dual-position bearings). A Toyota JZ starter motor without an additional nose cone / pinion cover must be used – see details in the FAQ section. The release bearing is included in the Sachs XTend kit; clutch fork and clutch slave cylinder are not included and must be selected to match your gearbox.
Toyota JZ series engines: 1JZ (1JZ-FSE, 1JZ-GE, 1JZ-GTE) and 2JZ (2JZ-FSE, 2JZ-GE, 2JZ-GTE), in both VVT-i and non VVT-i variants.
The 5-speed manual ZF S5D-280Z (ZF-5) gearbox from BMW M47 diesel models in versions THCI (E46 318d / 320d) and THCM (E39 520d). This gearbox features a 28x35-10N spline.
No. The adapter is designed to eliminate the need to cut the bellhousing – only an opening for the starter motor needs to be made.
A Toyota 1JZ / 2JZ automatic transmission ring gear / flexplate, OE 32101-30090 or 32101-22050, and one 4.5 mm spacer washer between the engine block and flexplate, Toyota OE 32116-22020. You will also need a clutch fork and clutch slave cylinder dedicated to the S5D-280Z transmission, as well as a Toyota JZ starter motor (see question below). These parts are not included in the kit.
Sachs XTend 3000 951 877 (BMW M57) with a diameter of 240 mm (9.45"): self-adjusting pressure plate, organic clutch disc with a 28x35-10N spline (10 teeth) for the ZF S5D-280Z gearbox, and a release bearing.
The maximum torque capacity of the kit is 650 Nm (479 lb⋅ft).
Yes. The PMC Motorsport flywheel is designed for a 240 mm BMW OE type pressure plate – from BMW M57 / M57N / M57N2 / N54 / B58 / E46 M3 or Sachs Performance 883082.001243. ACT / Spec / Tanaci clutches are also commonly used – any aftermarket pressure plate must fit the BMW OE flywheel pattern (M57 / M57N / M57N2 / N54 / B58). For the S5D-280Z gearbox, use a 240 mm clutch disc with a 28x35-10N spline.
A Toyota JZ starter motor without an additional nose cone / pinion cover. The mounting procedure depends on the adapter production year:
a) adapters produced up to 2022 – the starter motor is mounted identically to the original equipment (OE) setup;
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 fitted with the supplied AN 335-M10 sleeve and secured with an ISO 4762-M10x35 bolt;
c) adapters produced from January 2025 onwards – enlarge the lower starter mounting hole to ∅12–13 mm and tap the engine block to M12x1.5.
Yes. The PMC Motorsport gearbox adapter plate itself is universal and fits most BMW transmissions (applies to adapters produced after 2022). If you switch to another transmission, you only need to change the flywheel and clutch disc.
Yes. The PMC Motorsport adapter plate itself is universal and fits most BMW transmissions (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 plate.

Yes, if you are a B2B customer based outside Poland with a valid EU VAT number (verified via VIES) or if your order ships outside the EU.
The manual describes mating the engine to the transmission outside the car. Depending on your chassis, additional modifications may be required: engine mounts, bushings, firewall modifications, transmission tunnel clearance, and driveshaft length. We recommend professional installation.
Please note that a lightweight single-mass flywheel provides uncompromising throttle response at the expense of eliminating factory damping elements. This results in a more direct drivetrain operation, which may naturally increase gear chatter and mechanical transmission noise. This is a normal and expected characteristic in motorsport applications, resulting from the rigid mechanical connection between engine and drivetrain.
