Way Motor Works has installed many different diverter valves, blow off valves, and recirculation valves on Turbo MINIs over the years. But we have to say we have found the Forge Recirc valve kit to work the best. This Forge kit is available for both the N14 engine and N18 engine. The kit replaces the stock electric diverter valve completely with a new machined aluminum valve that is vacuum controlled with an electric solenoid plugged into the factory wiring for the ECU to maintain the operation. These Forge valves are able to hold more boost and operate faster than the original unit. This will help you build boost faster, longer, and dump it faster to prevent turbo surge.


Kit for N14 Cooper S and JCW

And the Kit for N18 Engine Cooper S, JCW, Paceman, and Countryman

 

I got this part for my 2007 r56 with jcw tune when it was stage 3. I never got to install it because I blew a piston. Now I have a new motor and stock copper s with the jcw kit.
Would this still be of use to me and what colour spring should I use?

 

Yes it will work fine on your car. Start with the spring that comes in it and see what you think, later you can swap it out and compare. If you don't like it you can go back.

 

Have anyone tried this with the N18 engine? Any trouble or CEL appearing?

 

We install them on N18's all the time. You have to T into the vacuum on the N18, you can't use the boost tap to have it work right.

 

Does it come with instructions on how its mounted, and where to T in. Is the T suplied in the kit for N18?

 

Yes the Kit comes with a great set of instructions.
