Race Stage 1 Toyota 1JZ 2JZ - 5-speed manual BMW M47 ZF5 S5D-280Z - 240mm / 9.45"

PMC Motorsport Race Stage 1 – Clutch Kit Toyota JZ 1JZ 2JZ – BMW M47 ZF S5D-280Z E46 318d 320d / E39 520d 5-Speed Manual – 240 mm / 9.45" – Sachs Performance 883082.001243 – max. 800 Nm / 590 lb⋅ft

Complete Race Stage 1 clutch kit designed to mate (swap / conversion) the Toyota JZ 1JZ 2JZ engine with the ZF S5D-280Z (ZF-5) 5-speed manual gearbox used in BMW diesel M47 models (E46 318d / 320d, E39 520d). The kit includes an adapter plate, a custom PMC Motorsport flywheel, a reinforced Sachs Performance 883082.001243 clutch pressure plate (non-SAC / without self-adjustment), and a PMC 240 mm sintered clutch disc with 28x35-10N spline. The maximum torque capacity of the kit is 800 Nm (590 lb⋅ft). Paired with the S5D-280Z transmission, the Race Stage 1 kit is engineered for motorsport – drifting, track days, and high-performance builds.

Planning a Toyota JZ 1JZ 2JZ swap into your BMW (E30, E36, E46, E34, E39, E90, E91, E92, E60, E61, E81, E82, E87)? Our adapter plate is a proven, reliable solution. Replace an automatic transmission with a robust BMW manual gearbox and unlock new potential.

PMC Motorsport adapters not only facilitate automatic-to-manual conversions in cars equipped with the Toyota JZ 1JZ 2JZ engine, but also support JZ engine swaps 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, eliminating drastic modifications such as cutting off the bellhousing – only preparing the starter motor opening is required. Custom flywheels dedicated to PMC Motorsport adapters are machined from aluminum with a replaceable friction surface, fully inspected and balanced prior to dispatch. Flywheel engineered for a 240 mm pressure plate (GS5-39DZ / GS6-53DZ / BZ BMW OE). Flywheel weight: 5.0 kg (11.0 lbs), adapter thickness: 20 mm (0.78").

PMC Motorsport gearbox adapter plates represent precision engineering and premium quality. A 3D scanning-based design process and CMM measuring arm quality inspection ensure an exact fit. Manufacturing on state-of-the-art CNC machinery guarantees flawless concentricity and alignment between engine and transmission, which is critical for drivetrain longevity.

Additional Information

Installation Instructions

To mount the custom flywheel, it is required to use the automatic flexplate / starter ring gear from an automatic Toyota version: Toyota OE 32101-30090 or 32101-22050, along with the 4.5 mm spacer placed between the engine block and flexplate, Toyota OE 32116-22020 (not included). Torque the flywheel to the crankshaft using the supplied bolts to 72 Nm (53.1 lb⋅ft) with high-strength threadlocker. Mount the clutch release fork on the lower pivot position of the release bearing (if using a dual-position release bearing). A Toyota JZ starter motor without an external pinion nose shield must be used to clear the adapter plate – see FAQ section for detailed instructions. The release bearing, clutch fork, and clutch slave cylinder are not included in the kit and must be selected to match your specific gearbox.

Frequently Asked Questions (FAQ)

Which engines is this kit compatible with?

With Toyota JZ family engines: 1JZ (1JZ-FSE, 1JZ-GE, 1JZ-GTE) and 2JZ (2JZ-FSE, 2JZ-GE, 2JZ-GTE), both VVT-i and non VVT-i variants.

Which gearboxes does the kit fit?

The 5-speed manual ZF S5D-280Z (ZF-5) transmission sourced from BMW M47 diesel engines in THCI (E46 318d / 320d) and THCM (E39 520d) configurations. The input shaft features a 28x35-10N spline.

Does the gearbox bellhousing require cutting?

No. The adapter is specifically designed to eliminate cutting the bellhousing – only preparing the starter clearance opening is necessary.

What additional components are required for complete installation?

The starter flexplate / ring gear from an automatic Toyota 1JZ / 2JZ, OE 32101-30090 or 32101-22050, and one 4.5 mm spacer washer placed between the engine block and flexplate, Toyota OE 32116-22020. You will also need the release bearing, clutch fork, and clutch slave cylinder suited for the S5D-280Z transmission, alongside a Toyota JZ starter motor (see below). These components are not included in the kit.

Which clutch is included in the package?

A reinforced Sachs Performance 883082.001243 (88 308 200 1243) pressure plate measuring 240 mm (9.45") without self-adjustment, accompanied by a PMC 240 mm sintered paddle clutch disc with a 28x35-10N spline (10 teeth) engineered for the ZF S5D-280Z gearbox.

What is the torque rating of the Race Stage 1 kit?

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

Is this kit suitable for a daily-driven car?

The Race Stage 1 kit with a sintered clutch disc is intended primarily for motorsport applications – clutch engagement is sharper and more aggressive than with an organic disc. For street cars driven daily, we recommend our Stage 1 kit equipped with a Sachs XTend clutch.

Can I run an alternative clutch pressure plate?

Yes. The PMC Motorsport flywheel is engineered to accept BMW OE 240 mm pressure plates – from BMW M57 / M57N / M57N2 / N54 / B58 / E46 M3 or Sachs Performance 883082.001243. High-performance aftermarket clutches from ACT, Spec, or Tanaci can also be fitted, provided the custom pressure plate matches the BMW OE flywheel pattern (M57 / M57N / M57N2 / N54 / B58). For the S5D-280Z gearbox, you must use a 240 mm clutch disc with a 28x35-10N spline.

Which starter motor must be used?

A Toyota JZ starter motor without an external pinion nose shield. Installation depends on the production date of your adapter plate:

a) Adapters manufactured up to 2022 – the starter motor installs identical to OE;

b) Adapters manufactured from 2022 to 2025 – one of the starter mounting holes in the engine block must be bored 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 down with an ISO 4762-M10x35 bolt;

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

Can I use this adapter with a 6-speed GS6-53DZ / GS6-53BZ gearbox?

Yes. The PMC Motorsport adapter plate itself is universal and fits the majority of BMW gearboxes (applies to adapters produced after 2022). If you switch to another BMW gearbox in the future, you only need to change the flywheel and clutch disc.

Is this adapter compatible with the ZF 8HP automatic transmission?

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

What is included in the kit?

Aluminum gearbox adapter plate with mounting hardware, custom PMC Motorsport flywheel with replaceable friction surface, crankshaft bolts, pressure plate mounting bolts, pivot pin – BMW OE 21 51 1 223 328 replacement – Sachs Performance 883082.001243 clutch pressure plate, and PMC 240 mm 28x35-10N sintered clutch disc. The release bearing, clutch fork, and slave cylinder are not included.

Can I purchase only the adapter plate or only the flywheel?

Yes. Every individual part of the kit is available separately – including the adapter plate paired with the custom flywheel, without the clutch assembly.

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

No. The product price and shipping quote do not cover import customs duties, tariffs, or local import taxes assessed by the destination country.

Can I place an order with 0% VAT?

Yes, if you are a registered B2B customer outside Poland holding an active EU VAT number (validated via the VIES system), or if your order is being exported outside the European Union.

Is the included installation manual sufficient to complete the conversion?

The manual details the mechanical mating of the engine and transmission outside the vehicle body. Depending on the vehicle platform, additional custom fabrication may be necessary: custom engine mounts, bushings, firewall adjustments, transmission tunnel modification, propshaft balancing and length alteration. Professional installation is highly recommended.

Please note that a lightweight single-mass flywheel provides razor-sharp throttle response at the expense of eliminating factory dual-mass damping elements. This yields a much more direct drivetrain connection, which may result in an audible increase in transmission gear chatter. This is a normal, inherent, and often desirable operational characteristic in competition and motorsport vehicles.
