Designed with precision for BMW Mini Cooper S models equipped with N18 engines, this product is tailored to fit Cooper S vehicles from 2011 onwards and JCW Cooper S from 2013 onwards. Whether you've recently boosted your vehicle's performance through an ECU software upgrade, desire an attention-grabbing Blow off sound, or need a dependable solution to prevent common failures, this product is the perfect choice for you.
Exclusively available in a limited edition Red color option at Turner Motorsport, it's an opportunity to make a bold and distinctive statement with your Mini Cooper S.
Forge Motorsport is thrilled to present a LIMITED EDITION version of their highly popular solenoid driven valve, specifically designed for the Gen 2 MINI Engine. This exceptional product is meticulously crafted to cater to BMW Mini Cooper S models equipped with N14 engines, including Gen 2 Cooper S 2007-2010 and JCW 2009-2012, featuring electronically controlled bypass valves. It's the ultimate choice for vehicles that have had their boost pressure increased through ECU software upgrades or for unmodified vehicles operating in warmer climates, providing a dependable solution to prevent common failures.
The stock valve on the N55 is prone to failure - the plastic often cracks, causing the valve to stop functioning altogether.
This Forge valve unit is engineered with a piston, eliminating the diaphragm entirely. Additionally, the Valve is all aluminum - this is the solution to any failures associated with the OEM valve, making your N55 significantly more reliable. This unit retains the OEM ECU controlled valve actuation as well. Includes a plug and play harness that works with the OEM harness.
Turner Motorsport advises being cautious when removing the OEM recirculating valve; if the plastic is cracked, pieces could fall into the turbo upon removal causing serious damage.
This product fits the following BMWs:
2014+ F22 M235i M235iX
It 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, where the original rubber diaphragm splits, which causes a loss of boost pressure. Unfortunately the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this.
Our alternative is a fully engineered solution offering significantly improved reliability. Our valve is piston based with no diaphragm to fail, and of all aluminium 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.

In addition to the weak stock chargepipe, the factory N54 diverter valves can also be a source for boost leaks. The diverter valve takes overboost and re-directs it back through the intake and turbos instead of allowing it to pass into the intake manifold. It's the same as a blow off valve (BOV) but instead of releasing into the engine bay, it stays contained to the engine. The stock diverter valves (DV) are plastic and connect with more plastic into the chargepipe and turbo inlet pipes. The plastic can become brittle and crack even on stock engines and leak boost, which leads to a loss in power and performance.
Turbosmart has developed two kits to replace and upgrade the stock diverter valves - a direct replacement kit and a combination DV/BOV "Dual Port" kit (shown). This Dual Port Kit is a DV and a BOV together in one unit. An internal valve directs some of the charged air into the turbo inlets and the rest is dumped into the engine bay like a traditional BOV. The amount of boost released into the air is determined by an internal spring in the Dual Port unit (additional springs are also available). This allows you to custom tailor how much boost and BOV "whoosh" you hear. In addition to the DV/BOV combo, stronger silicone hose is included to connect them to the turbo inlet pipes (Vargas silicone inlets are recommended). The Turbosmart Kompact Dual Port will give you all of the strength and reliability you need to take your turbo build to the next level.

This alloy hard pipe fits to the throttle body and incorporates our high flow Blow off valve. This new valve fresh from our R&D department is the largest displacement valve that Forge have ever made ! Featuring a 50mm (2”) aluminium piston so that there are no issues with split diaphragms, we have not found the power handling limits of this valve yet ! The piston uses heat stabilised viton o-rings and high temperature Mobil 1 grease to ensure a long life with minimal wear and very long service intervals.
All parts are included in the kit, for your installation, along with comprehensive instructions.
This product fits the following BMWs:
2008 - 2013 E82 135i
2007 - 2013 E9x 335i
Optimize your BMW's performance by adjusting your diverter or blow-off valve using this kit containing four springs with varying strengths. When noticing excessive pressure release or a drop in boost pressure, it's an indicator that a stronger spring might be necessary.
