VW / Audi 1.8 Litre to Borg Warner T5 Competition Bellhousing Kit
This bellhousing kit will mate the Volkswagen, Audi, SEAT or Skoda 1.8 litre 20 valve turbocharged engines to the Borg Warner T5 (2WD Cosworth) gearbox.
The kit includes the VW / Audi to Borg Warner T5 bellhousing, RWD Motorsport lightweight steel flywheel, Mondeo slave cylinder, Sachs racing clutch pressure plate, solid paddle clutch plate, spigot bearing, bellhousing bolts, gearbox bolts and slave cylinder mounting bolts.
The standard Mondeo slave cylinder, connects via an included adaptor directly to the bellhousing rear inner face. The nose of the T5 will need to be cut down to allow the slave cylinder to slide over but this will not affect the integral oil seal.
The clutch will handle 425 ft lb or 576 Nm of torque.
Please see our VW / Audi 1.8 Turbo page for more information.
* Requires a spigot bearing from the longitudinal Audi A4 engine.
** Starter required is the Audi A4 1.8 turbo variant
*** The bottom bellhousing holes are spaced to fit the inline A4 sump. If using a transverse sump or other engine variants, the sump holes will not align. In a RWD application this is not a structural issue as the engine is supported at the midpoint and the engine / gearbox assembly is not subjected to the same forces.
**** If using a USA or Australian T5 gearbox you may need our 10 spline 1 1/16″ clutch friction plate which we can replace for the standard 23 spline 1″ Sierra Cosworth friction plate (please contact us).
