RB20/25/26/30 – BMW gearbox adapter KIT

Nissan RB engine to BMW gearbox adapter flange.

Our kit allows you to run RB engine with bullet proof BMW manual gearbox and make it RWD. The kit is Plug and play to run the BMW gearbox, you should use the BMW starter motor with this kit, and need some small cutting in bellhousing.

Complete RB to BMW gearbox adapter flange kit includes:

  • Flywheel (to work with Tilton 7.25” 2-3 disc clutches)
  • Adapter flange
  • Tilton OT II clutch (2 plate 900nm / 3 plate 1500nm)

  • All necessary bolts EXCEPT crank bolts (ARP crank bolts optional)
  • Instruction manual

  • E46 m3 6speed (2000-2006)
  • E36 m3 6speed (1995-1999)
  • E39 3.0d 5speed (1998-2000)
  • E46 3.0d 5 speed (1999-2005)
  • E46 2.0d 5 speed (2001-2005)

These boxes are proven to be bullet proof and have been seen on applications up to 1500 nm. These boxes in good condition allow really fast shifting.

Adapter kit is ABC Clutch designed, manufactured and tested. All parts are CNC machined, checked and treated against corrosion. All measurements are taken with CNC dial-up gauge from OEM Toyota/BMW/Tilton parts for proper engine and gear box center collinear alignment fitting.

There are many adapter plates on the market, but ABCs are the only ones with centering pins, to get crankshaft center and gearbox input shaft aligned precisely. This guarantees that the multi disk clutch spline won’t be damaged caused by incorrect alignment. This is the same problem with Cut and Welded bell housings which during the welding will warp causing the misalignment.
