Adapter kit allowing connection (swap / conversion) of the Toyota JZ 1JZ 2JZ engine (GE / GTE / FSE, VVT-i and non VVT-i versions) with the 5-speed manual gearbox ZF-5 (ZF S5D-310 / S5D-320) or Getrag S5D-250G used in BMW with M50 / M52 / M54 / S50 / S52 engines, as well as the 6-speed Getrag 420G gearbox from BMW E36 M3 (S50). An ideal solution for amateur and professional motorsport.
Planning a Toyota JZ 1JZ 2JZ swap in your BMW (E30, E36, E46, E34, E39, E90, E91, E92, E60, E61, E81, E82, E87)? Our adapter is a reliable solution. Swap your automatic transmission for a manual BMW gearbox and unlock new possibilities.
PMC Motorsport adapters not only enable automatic to manual gearbox conversion in vehicles with the Toyota JZ 1JZ 2JZ engine, but also support completing JZ swaps in BMW as well as other vehicles.
Aluminum gearbox adapter designed to simplify gearbox installation as much as possible without radical modifications like cutting off the bellhousing – only preparing a cutout for the starter motor is required. Custom flywheels dedicated to PMC Motorsport adapters are made of aluminum with a replaceable friction surface, tested and balanced before shipping. Flywheel designed for 240 mm pressure plate (BMW M57 / M57N / M57N2 / N54 / B58 / E46 M3 OE).
PMC Motorsport gearbox adapters are synonymous with precision and top quality. The design process based on 3D scanning and inspection using a measuring arm ensure a perfect fit. Production on modern CNC machines guarantees ideal concentricity of the engine and transmission, which is crucial for the durability of the drivetrain.

PMC Motorsport parts are intended for motorsport and racetrack use only.
Parts intended for installation by professionals with knowledge of engine swaps and car modifications – in workshops and using properly adapted tools.
The adapter installation manual provides only basic knowledge required to physically couple the engine to the gearbox outside the car body.
Depending on the specific car, additional modifications may be required, such as: custom mounts, bushings/mounts, firewall modification, transmission tunnel clearance, driveshaft custom length, etc.
We manufacture adapters using 100% recyclable materials.
To install the flywheel, it is necessary to use the flexplate / starter ring gear from automatic version Toyota 1JZ / 2JZ OE 32101-30090 (3210130090) or OE 32101-22050 (3210122050) and a Toyota OE 32116-22020 (3211622020) 4.5 mm spacer plate between the engine block and the ring gear (not included).
For adapter installation, a Toyota JZ OE starter motor without an additional pinion cover must be used (not included). Enlarging the lower mounting hole of the JZ starter motor is required – the installation method depends on the adapter's manufacturing year (details in the FAQ section).
Mount the clutch release fork on the lower position of the release bearing (in case of a 2-position bearing).
In ZF-5 (ZF 310 / ZF 320) and Getrag 250 / 420G gearboxes, the two upper holes in the gearbox housing (bellhousing) must be slightly grinded – this modification does not affect the centering of the engine and gearbox.
Release bearing, clutch release fork, and slave cylinder are not included in the kit: BMW OE release bearing 21 51 7 521 360 (1-position) or 21 51 7 570 154 (2-position), BMW OE clutch release fork 21 51 1 223 302 (1-position) or 21 51 7 564 027 (2-position), BMW OE slave cylinder 21 52 1 164 529 (Ø 23.81 mm).
For Toyota JZ engines: 1JZ (1JZ-FSE, 1JZ-GE, 1JZ-GTE) and 2JZ (2JZ-FSE, 2JZ-GE, 2JZ-GTE), in VVT-i and non VVT-i versions.
For 5-speed ZF-5 (ZF S5D-310 / ZF 310 and ZF S5D-320 / ZF 320) and Getrag S5D-250G gearboxes from BMW with M50 / M52 / M54 / S50 / S52 / S54 engines (including E36 328i, E46 328i / 328Ci / 330i, E34 525i, E39 525i / 528i / 530i, Z3 2.8i / 3.0i), as well as the 6-speed Getrag 420G (TBAB, TAGU) gearbox from BMW E36 M3 (S50). Flywheel does not fit BMW M54 6-speed manual gearbox.
No. The adapter is designed to avoid cutting the bellhousing – only a cutout for the starter motor needs to be prepared.
The PMC Motorsport adapter is the most universal adapter available on the market, supporting virtually every BMW gearbox. When designing it, we decided on a slight compromise – in Getrag 250 / Getrag 420 / ZF 310 / ZF 320 / ZF-5 gearboxes, the two upper holes in the gearbox housing (bellhousing) must be slightly grinded. This modification does not affect the centering of the engine and gearbox.
Starter ring gear (flexplate) from Toyota 1JZ / 2JZ automatic version – OE 32101-30090 (3210130090) or OE 32101-22050 (3210122050) – and one Toyota OE 32116-22020 (3211622020) 4.5 mm spacer plate installed between the engine block and the ring gear. A Toyota JZ starter motor is also required (see question below). These parts are not included in the kit.
Toyota JZ OE starter motor without an additional pinion cover. Starter motor is not included in the kit. The mounting method depends on the adapter's manufacturing year:
a) adapters manufactured up to 2022 – 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 enlarged: drill with a bit to a diameter of ∅12.9–13.2 mm (0.507"–0.520") to a depth of 22 mm (0.866"), use the bushing from the AN 335-M10 kit and bolt with an ISO 4762-M10x35 bolt;
c) adapters manufactured from January 2025 – the lower mounting hole in the starter motor must be enlarged to a diameter of ∅12–13 mm and the engine block threaded to M12x1.5.
240 mm (9.45") BMW OE type pressure plate – from BMW M57 / M57N / M57N2 / N54 / B58 / E46 M3 or Sachs Performance 883082.001243. Clutches from ACT / Spec / Tanaci are also often used – custom pressure plates must fit the BMW OE flywheel (M57 / M57N / M57N2 / N54 / B58). For the ZF-5 gearbox, use a 240 mm clutch disc with 23x29-10N splines, a dedicated release bearing kit, and a slave cylinder.
Yes. The PMC Motorsport gearbox adapter itself is universal and fits most BMW gearboxes (applies to adapters manufactured after 2022). In case of changing the gearbox, you only need to replace the flywheel and clutch disc.
Yes. The PMC Motorsport gearbox adapter itself is universal and fits most BMW gearboxes (applies to adapters manufactured after 2022). When converting to a ZF 8HP automatic transmission, the standard flywheel must be replaced with the PMC Motorsport 8HP torque converter adapter.
Yes. Every component of the kit is available separately.
No. Product price and shipping estimate do not include customs duties or extra fees that may apply in the destination country.
Yes, if you are a B2B customer outside Poland with an active EU VAT number (verified in VIES) or ordering for export outside the EU.
The manual describes joining the engine and gearbox outside the chassis. Depending on the car, extra modifications may be needed: mounts, bushings, firewall, transmission tunnel, driveshaft length. Professional installation recommended.
It is worth noting that a lightweight single-mass flywheel provides uncompromising throttle response at the expense of eliminating factory dampening elements. This results in a more direct drivetrain operation, which can naturally increase the noise generated by the gearbox mechanism. This is a desirable characteristic in sports vehicles resulting from the rigid engine-to-drivetrain connection.
