Forge Motorsport Valve Spring Tuning Kit Forge Motorsport Valve Spring Tuning Kit

Now you can fine tune your Blow Off/Diverter Valve to the exact needs of your engine with this complete tuning kit. Your valve tuning kit you will find four springs. We normally supply our valves, unless requested differently, with a spring that will match the tension of the manufacturer’s original fitment valve. However, as many owners undertake tuning modifications some may wish to re-tune the valve characteristics to suit a given application.

Valve Spring color coding: Green - 5-15 PSI, Yellow - 15-23 PSI, Blue - 23-30 PSI, Red - 30 + PSI.
*The above figures are estimates only and should only be considered as a guideline*

If you are finding that the valve is dumping more than required or you are loosing boost pressure, it is normally an indication that a stronger spring is required. Conversely, if the valve is failing to dump it may be necessary to install a weaker spring. For example, if during the tuning of your valve, you are faced with the red spring being too strong and the blue spring too weak, you can add the spacers/shims to the blue spring to increase the tension by small increments, thus achieving a setting between the red and blue springs.

Note: Fitting a stronger spring into a valve will not increase boost pressure unless existing pressure is being lost. Failure to allow the valve to operate by installing a spring which is too strong, may cause damage to the turbocharger.

Please contact us if you are uncertain whether this kit is suitable for your valve.

*Please Note - The colors of the springs illustrated may differ to what you receive. All spring kits are brand new but are not sprayed. Colour is used as an identifier*

Forge Motorsport The Splitter, a Recirculation and Blow Off Valve MK4 1.8T Forge Motorsport The Splitter, a Recirculation and Blow Off Valve MK4 1.8T

The Splitter is a truly remarkable valve that gives a combination of blow off and recirculation valve operation, all at the same time, and has been specifically designed for the many turbo engined applications that operate metered airflow management systems. This means you get all the noise of the blow off valve whilst retaining the compatibility with the recirculation requirements of the engine management system. As a bonus we also offer the ability to convert the valve to recirculation only mode for those times when stealth running is required.

This valve uses a Brass piston which utilises new sealing technology along with a variable spring preload, incorporating a ratchet type top adjuster that will allow for the positive and precise adjustment to match the valve to your engine. This is achieved by using a unique single, conical, progressive rate spring, that can allow for the retention of boost pressure over a wide adjustment range. This unique spring design also allows for unrestricted piston travel and flow volume regardless of the amount of pre-load adjustment added to the spring.

Other manufacturers' valves use cylindrical springs with adjustable pre-load, which often experience restricted piston travel and a reduction in flow volume. When we say our products are Engineered For Performance, it's not a catchy sales phrase, it's the truth. and we prove it with every product we manufacture.

Note: This valve requires installing the opposite way to the original Bosch Valve. This means that the side pipe is fitted into the Turbo Intake Hose, and the base pipe connects to the hose that runs to the boost side of the turbo.

Forge Motorsport Recirculation Valve and Kit for Audi and VW 1.8 and 2.0 TSI Forge Motorsport Recirculation Valve and Kit for Audi and VW 1.8 and 2.0 TSI

Product Description

Forge Motorsport is proud to release the latest version of our very popular solenoid driven valve for the 2013-on VAG 1.8 TSI engine (US codes CPKA and CPRA) and 2.0 TSI engine (Euro code CNTA, CHHA, CHHB, CJXB and CJXC;US codes CPLA and CPPA) including Golf MK7 R

This valve is fully engineered to remedy the failure issues experienced with the OEM solenoid valves when their diaphragm may rupture which results in a boost leak. The later revision OEM valves have a longer lift but ultimately the plastic brittles and in extreme circumstances, parts of the plastic can break off. Our valve uses full billet alloy construction with a piston based internal design that provides for significantly improved reliability over the OEM valves along with lightning fast response. It has also been proven in cars running over 600bhp!

This new valve has a very short overall installed height, which enables fitment of this atmospheric valve into the tight space between the turbo and the inlet hose from the airfilter, older larger valves and sandwich plates will not fit this engine.

Forge Motorsport Blow Off Valve and Kit for Audi, VW, SEAT, and Skoda Forge Motorsport Blow Off Valve and Kit for Audi, VW, SEAT, and Skoda

Product Description

Forge Motorsport offer this valve option for the 1.4T, 1.8T & 2.0T FSI and TSI engines, including the late 2011-2013 fitted with the IHI turbo, (the 1.4T needs additional fitting kit FMBGFK3) found in a wide range of vehicles from VW and Audi.

This valve, part number FMFSITAT, is a hybrid of sorts, that combines our existing full replacement solenoid controlled recirculating valve with our blow-off valve adapter. The result is a full replacement atmospheric blow-off valve that integrates seamlessly with the OEM electronics and results in absolutely no fault codes, no check engine lights, and no detriment to the performance of the vehicle in any way. Like our full replacement recirculating valve option, the FMFSITAT is fully engineered to remedy the failure issues experienced with the OEM solenoid valves when their diaphragm may rupture which would effectively result in a boost leak.

Our valve uses full billet alloy construction with a piston based internal design that provides for significantly improved reliability over the OEM valves along with lightning fast response. This valve is particularly well suited to the B7 and B8 chassis Audi A4 and A5 with the 2.0T engine. The valve mounting location on these vehicles is positioned particularly close to the frame rail of the chassis, and the overall installed height of our standard replacement valve and spacer combination is such that it conflicts with the chassis at this location.

The FMFSITAT valve has a much shorter overall installed height, which enables fitment of this atmospheric valve option onto the B7 and B8 chassis whereas this was previously not an option. Another particularly unique feature of this product is the included intake manifold tap used to source a vacuum reference for the operation of the valve. This piece also has two other available provisions from which an intake manifold reference can be taken. These extra manifold references can be used for a boost gauge signal, and even a water/meth injection trigger where applicable. If this to be installed to the 1.4 Turbo engine, it will be necessary to additionally purchase our boost sensor adaptor FMBGFK3 - please see below in Related Products.

Note: This will ONLY fit the 1.4 turbo engines up to early 2013, where the turbo is mounted at the front of the engine bay. It will not fit engine codes CMBA & CXSB

In The Box:
1 x FMFSITAT Valve
1 x Wiring Harness
1 x Solenoid, Bracket, and Screws
1 x PCV Adaptor Kit
1 x Blue Spring (Uprated)
10 x Cable Ties
1 x 2000mm Length of 4mm Vac Hose
1 x Instruction Booklet
1 x Forge Keyring and Sticker

Product Description

This valve is for VAG vehicles equipped with the 1.4T, 1.8T & 2.0T FSI or TFSi engines, including the latest models fitted with the IHI turbo, (or 1.4T using additional fitting kit FMBGFK3) that have the electronically controlled bypass valves. It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles fitted with the earlier version of the OEM valve that operate in warmer climates, as a solution to the many failures of the diaphragm that have occurred.

Our alternative is a fully engineered solution offering both significantly improved reliability. Our valve and installation kit replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation. This product has been thoroughly designed and tested with the expressed intent of offering improved valve response and maintaining ECU control while resulting in absolutely NO fault codes, NO check engine lights, and no adverse effects of any kind.
