Ford Cosworth YB 4x4

Ford Cosworth 4x4/RX8 adapter

This adapter plate was designed to bolt a Ford Cosworth 4x4 engine to an rx8 gearbox using as many of the engines standard parts as possible. It utilizes the engines original starter motor/flywheel and clutch aslong as it is a 23 spline ford unit.

In most cases it is possible to use the rx8 clutch arm slave cylinder and release bearing with very little work, but In some cases the clutch arm pivot point height might need adjusting to suit. We recomend mocking this up out of the car. Spigot bearing RX8017 is to be used with this adapter. Fitting kit RX8018 can be used to bolt the engine adapter and gearbox bellhousing together.


Tested in motorsport to ensure we offer the most reliable adapter plate on the market.
