Drift Stage 2 Nissan SR - manual 6-speed BMW M57n GS6-53DZ HGD JGA HGA - 240mm / 9.45"

PMC Motorsport Drift Stage 2 – Clutch Kit Nissan SR20 SR20DE SR20DET – BMW M57N ZF GS6-53DZ HGD JGA HGA E60 530d / E46 330d 6-Speed Manual – 240 mm / 9.45" – BMW 240 mm Pressure Plate without Self-Adjustment – max. 700 Nm / 516 lb⋅ft

Complete Drift Stage 2 clutch kit designed to mate (swap / conversion) the Nissan SR20 (SR20DE / SR20DET) engine with the ZF GS6-53DZ HGD / JGA / HGA 6-speed manual gearbox sourced from BMW diesel M57N / M57N2 models (E60 / E61 530d, E46 330d), as well as its GS6X53DZ xDrive all-wheel drive version. The kit includes a gearbox adapter plate, a custom PMC Motorsport flywheel, a BMW 240 mm clutch pressure plate without self-adjustment (non-SAC), a rigid sintered clutch disc PMC 240 mm with 32.5x35-26N spline, and a release bearing with clutch fork. The maximum torque capacity of the kit is 700 Nm (516 lb⋅ft). Due to its direct characteristics, the kit is engineered for motorsport – drifting, track days, and high-power turbo builds.

Planning a Nissan SR20 engine swap into your BMW (E30, E36, E46, E34, E39, E90, E91, E92, E60, E61, E81, E82, E87)? Our adapter plate is a proven, reliable engineering 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 powered by the Nissan SR20 engine, but also streamline SR20 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 radical 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). 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

Crankshaft bolts are included in the kit. Mount the clutch release fork from the kit on the lower pivot position of the release bearing (if using a dual-position release bearing). An original Nissan SR20 starter motor (OE, not included) must be used to mount the adapter plate. The release bearing and clutch fork are included in the kit. The clutch slave cylinder is not included – use a slave cylinder dedicated to your specific gearbox.

Frequently Asked Questions (FAQ)

Which engines is this kit compatible with?

With Nissan SR20 engines in rear-wheel-drive (RWD) configurations: SR20DE and SR20DET.

Which gearboxes does the kit fit?

With the 6-speed manual ZF GS6-53DZ transmission from BMW M57N / M57N2 diesel models in HGD (THGD) and JGA (TJGA) versions – E60 / E61 530d – and HGA (THGA) – E46 330d, as well as the ZF GS6X53DZ xDrive transmission (HGB, HGE, JGB).

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?

A clutch slave cylinder dedicated to your gearbox and an original Nissan SR20 starter motor (see question below). These parts are not included in the kit.

Which clutch is included in the package?

A BMW 240 mm (9.45") clutch pressure plate without self-adjustment and a rigid PMC 240 mm clutch disc with sintered metal (cerametallic) friction pads, featuring a 32.5x35-26N spline (26 teeth) for the ZF GS6-53DZ gearbox. The kit is completed by a release bearing and clutch fork.

What is the torque rating of the Drift Stage 2 kit?

The maximum torque capacity of this kit is 700 Nm (516 lb⋅ft).

Is this kit suitable for a daily-driven car?

The Drift Stage 2 kit with a rigid sintered clutch disc is intended primarily for motorsport – clutch engagement is sharper and less smooth 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).

Which starter motor must be used?

An original Nissan SR20 (OE) starter motor. The starter motor is not included in the kit.

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

Yes. The PMC Motorsport gearbox 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 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 –, BMW 240 mm clutch pressure plate without self-adjustment, PMC 240 mm 32.5x35-26N rigid sintered clutch disc, and release bearing with clutch fork.

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.
