MINI Cooper Valve Kit (N14 Engine - Uprated) by Forge (R55 / R56 / R57 S Model)
This valve is for the MINI 1.6 Turbo engines, and MINI Cooper S Turbo R55/56/57 models with the N14 engines. These are found in the Cooper S 2007-10 or JCW Cooper S 2007-12 . This solution is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade, and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred.
The other problem is that diaphragm retaining ring is made from very thin plastic that goes brittle with heat cycles and oil contamination, and eventually fails. This prevents the diaphragm from sealing with the same problems as mentioned above. This particular failure also results in the valve falling apart upon removal from the turbo, though in extreme cases bits of plastic can enter the turbo and destroy it.
Forge's alternative is a fully engineered solution offering both significantly improved reliability. The valve is piston based, with no diaphragm to fail, and of all aluminum construction, it replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation. The valve has been proved on the VAG scene for many years. The spring is interchangeable for different levels of boost, and the solenoid is plug and play with the wiring harness which is included.
