Adapter plate enabling the connection (swap / conversion) of the Toyota JZ 1JZ 2JZ engine with the ZF S5D-280Z (ZF-5) 5-speed manual gearbox used in BMW vehicles with the M47 diesel engine (E46 318d / 320d, E39 520d). This is an easily accessible and durable gearbox – its bellhousing and dimensions are frequently used in sequential and dog-leg transmissions. A perfect solution for amateur and professional motorsport alike.
Planning a Toyota JZ 1JZ 2JZ engine swap in your BMW (E30, E36, E46, E34, E39, E90, E91, E92, E60, E61, E81, E82, E87)? Our adapter plate is a reliable solution. Replace the automatic transmission with a BMW manual gearbox and unlock new performance capabilities.
PMC Motorsport adapter plates not only provide automatic-to-manual transmission conversions in vehicles powered by the Toyota JZ 1JZ 2JZ engine, but also facilitate JZ engine swaps into BMWs and other chassis, such as the Nissan (S13, S14, S15, PS13) or Mazda RX-7 / RX-8.
Aluminum gearbox adapter plate engineered to simplify gearbox installation as much as possible, avoiding radical modifications such as cutting the entire bellhousing – only preparing an opening for the starter motor is required.

PMC Motorsport parts are intended for motorsport and closed racetrack use.
Parts intended for installation by professionals with knowledge of engine swaps and automotive conversions – in proper workshop conditions and using suitable tools.
The adapter installation manual covers only the basic knowledge required to physically mate the engine and gearbox outside the vehicle body.
Depending on the specific car chassis, additional modifications may be required, such as: customizing engine mounts, bushings, firewall clearance, transmission tunnel clearance, driveshaft length, etc.
Our adapter plates are manufactured from fully recyclable materials.
Installing the flywheel requires the automatic transmission flywheel (flexplate / ring gear) Toyota OE 32101-30090 or 32101-22050 and a 4.5 mm spacer washer between the engine block and ring gear, Toyota OE 32116-22020 (not included). Bolt the flywheel to the crankshaft using the supplied bolts to 72 Nm (53.1 lb⋅ft) using threadlocker. Mount the clutch fork on the lower release bearing position (in the case of a dual-position bearing). To mount the adapter plate, use a Toyota JZ starter motor without an additional pinion snout/cover – see details in the FAQ section.
Toyota JZ engine family: 1JZ (1JZ-FSE, 1JZ-GE, 1JZ-GTE) and 2JZ (2JZ-FSE, 2JZ-GE, 2JZ-GTE), in both VVT-i and non VVT-i versions.
The 5-speed manual ZF S5D-280Z (ZF-5) gearbox from BMW with the M47 diesel engine in THCI (E46 318d / 320d) and THCM (E39 520d) variants. The gearbox input shaft has a 28x35-10N spline.
No. The adapter plate is designed to eliminate the need to cut the bellhousing – you only need to prepare a clearance notch/opening for the starter motor.
The automatic transmission flywheel (flexplate / ring gear) Toyota 1JZ / 2JZ, OE 32101-30090 or 32101-22050, and one 4.5 mm spacer washer between the engine block and ring gear, Toyota OE 32116-22020. You will also need a 240 mm clutch pressure plate and clutch disc (28x35-10N), release bearing, clutch fork, and clutch slave cylinder dedicated to the S5D-280Z gearbox, and a Toyota JZ starter motor (see question below). These parts are not included in the kit.
A 240 mm (9.45") BMW OE type clutch pressure plate – from BMW M57 / M57N / M57N2 / N54 / B58 / E46 M3 or Sachs Performance 883082.001243, as well as Sachs XTend 3000 951 877 (BMW M57). 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 dedicated release bearing assembly, and a matching slave cylinder.
A Toyota JZ starter motor without an additional pinion snout/cover. The installation method depends on the adapter version:
a) adapters manufactured up to 2022 – the starter motor installs identically to original equipment (OE);
b) adapters manufactured 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 install the sleeve from the AN 335-M10 kit and bolt it down with an 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 and the engine block threaded to M12x1.5.
Yes. The PMC Motorsport adapter plate itself is universal and fits most BMW gearboxes (applies to adapters manufactured after 2022). If you switch to another gearbox model, you only need to replace the flywheel and clutch disc.
Yes. The PMC Motorsport adapter plate itself is universal and fits most BMW transmissions (applies to adapters manufactured after 2022). When converting to a ZF 8HP automatic transmission, the standard flywheel is replaced with a PMC Motorsport 8HP torque converter adapter.
Aluminum gearbox adapter plate with mounting bolts, custom PMC Motorsport flywheel with replaceable friction surface, crankshaft bolts, pressure plate mounting bolts, and clutch fork pivot pin – replacement for BMW OE 21 51 1 223 328. The clutch, release bearing, clutch fork, and slave cylinder are not included in the kit – they must be selected to match your specific gearbox.
Yes. Every component of the kit is available separately.
No. The product price and shipping quote do not include customs duties or additional import taxes that may be levied in the destination country.
Yes, if you are a B2B customer outside Poland with an active EU VAT ID (verified in the VIES system) or if your order is shipped outside the EU.
The manual describes mating the engine and gearbox outside the vehicle body. Depending on the car chassis, additional modifications may be required: mounts, bushings, firewall clearance, transmission tunnel shaping, driveshaft length adjustments. We recommend installation by professionals.
Please note that a lightweight single-mass flywheel provides uncompromising throttle response at the expense of eliminating factory damping elements. This results in more direct drivetrain operation, which may naturally increase gear rollover noise from transmission mechanisms. This is a normal, desired characteristic in motorsport vehicles resulting from the rigid mechanical connection between the engine and drivetrain.
