T7Design K20 to S2000 Gearbox Adapter Plate Kit

The T7Design K20 to S2000 Adapter Plate Kit has been designed to seamlessly pair the renowned K20 engine with one of the finest manual RWD gearboxes available. This creates one of the best combinations of engine and drivetrain, ready to be integrated into any RWD chassis!

We set out to offer a RWD kit for the K20 engine to function with the S2000 gearbox as if it had been available from factory, therefore we wanted to ensure compatibility with as many OEM parts as possible to allow the package to operate and drive like a standard vehicle, and also be compatible with many aftermarket race clutches for motorsport use. This kit will work perfectly well for a daily driver or an all-out race car!

A lot of work, consultation, and FEA has gone into developing our flywheel to ensure that it is as light as possible without sacrificing strength and durability for high-RPM use and are pleased to have ended up with a weight of just 4.99kg. Not only does this make it the lightest K2F flywheel on the market by a reasonable margin but it is also only 0.5kg heavier than the weight of a stock K20A2 flywheel, despite being 2.5x as thick!

PLEASE NOTE: Please check the compatibility list below prior to ordering.

  • The kit has been designed to work with the stock S2000 friction plate, S2000 clutch housing, and S2000 throw-out bearing, or aftermarket clutches that are compatible with the OEM S2000 flywheel.
  • Designed to use the OEM K20 clutch case dust cover.
  • Designed to use the OEM K20 starter motor.
  • Adapter plate is CNC machined from billet aluminium plate.
  • Single piece lightweight, K2F flywheel CNC machined from Chromoly Steel, weighing in at 4.99kg (11lbs) inc pilot bearing. This is the lightest K2F flywheel on the market and weighs in only a few hundred grams heavier than the OEM K20A2 flywheels.
  • Flywheel is supplied with pilot bearing installed.
  • Utilises OEM Honda dowels both sides of the plate for perfect alignment.
  • Designed using full 3D laser scans of both the K20, F20C engines, S2000 Gearbox and all original flywheel and clutch components.
