What it does:

Greatly reduces the transer of heat from engine to intake manifold thus reducing heat soak.One of a kind true Phenolic material, not cutting board material like others.The cooler your intake temperature is the denser the air is which leads to more powerFor every 5 degree reduction in air temperature, increases power by 1%.The cooler and denser the intake air that the engine sucks in, increases the amount of air that can be mixed with fuel thus increasing efficiency.

How it works:

The intake air in your engine travels through the airbox into the turbo, then into the aluminum intake manifold. The air exits the intake manifold and goes directly into the engine.

While the intake air is within the intake manifold it picks up alot of heat from the aluminum intake manifold. This added heat reduces air density thus reducing engine power capabilities.In stock form your engine has a steel gasket between the intake manifold and engine which allows the heat from the engine to quickly transfer into the intake manifold. By replacing this steel gasket with the GrimmSpeed™ Phenolic Spacer you are greatly reducing the transfer of engine heat into the intake manifold.Phenolic Spacers are able to withstand 500+ degrees F. Subaru engines run at the hotter end of operation around 200 degrees F, so the Phenolic Spacer is well within its max running temperature. GrimmSpeed™ has tested that it is also safe to run race fuel, E85, and methanol with the Phenolic Spacers.The Phenolic Spacer will conduct 300-900 times less heat than the oem steel gasket.

Using GFB’s TMS technology the Mach 2 can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears (more information below).

• Recirculation model for direct factory replacement for performance without the noise
• Atmosphere venting kits to convert the recirculating valve if you want noise with your performance

Like the Respons and Deceptor Pro II, the Mach 2 is available in a range of bolt-on kits for most popular turbo models. And when we say “bolt-on”, that’s exactly what we mean! No additional adaptors, parts or vehicle modifications are required – simply remove the factory bypass valve and replace it with the Mach 2 – it’s that simple!

The Mach 2 is configured as a 100% recirculating valve (i.e. bypass, plumb back) and add on kits are also available to convert to 100% atmosphere venting.

Use the recirc model for direct factory replacement when you want the performance WITHOUT the noise! Add the conversion kit when you want some noise with your performance!

Factory bypass valves have two main shortcomings – one is that they are typically designed to start opening above a certain pressure to protect the engine, and the other is they are not optimised for throttle response. Oh, and you can’t vent them to atmosphere without stalling your engine…
The Mach 2 solves all of these issues. It can effectively hold unlimited boost (unlimited in that no turbo could ever produce enough pressure to damage it), and the TMS technology ensures maximum throttle response

Install Guide

So how much more can you do with a blow-off valve? Well, the Deceptor Pro II takes the ‘Respons’ concept even further...

• Remote proportional venting bias/volume control- from silent to loud or anywhere in between
• Sleek, compact in-car BOV volume controller with backlit dial
• End point adjustment to control maximum vent to atmosphere bias setting
• Volume adjustment mechanism driven by a high-torque geared electric motor
• Durable, low-friction gear train supported by precision sealed ball-bearing
• Supplied with all parts and wiring required to have it up and running quickly and easily

GFB's Short Shift kits are like no other. Until you feel the action of one for yourself, you won't believe the difference!

GFB's unique system means that not only is the shift throw distance fully adjustable, it can be reduced more than any other brand by a long shot (at the shortest setting, the throw from 3rd to 4th is a mere 55mm), whilst retaining the stock gearstick height.If you want a race-car feel when you change gears, look no further than a GFB short shift kit, the shortest throw shifter on the market!

Designed by Xtreme Clutch an Australian brand known for performance and quality within the Japanese tuner scene. This lightweight single mass chromoly flywheel is both strong and reliable (compared to OE dual mass flywheels) and provides increased engine response which is ideal for use on performance vehicles.

• Made from a tough & lightweight high carbon chromoly steel
• Reduced weight provides increased engine response
• Ideal for use in performance vehicles

Made from a high carbon chromoly steel, this flywheel is both strong and lightweight. Engineered to have an increased thermal capacity, this flywheel is an ideal choice for high performance engine applications.

Additionally fitting this lightweight flywheel can result in easier gear-shifts (example, revs dropping quicker for upshifts and raising quicker on a throttle blip for downshifts).

Being both strong and lightweight ensures a combination of both reliability and responsiveness, which are desirable qualities when used in a high-performance vehicle.

GFB have re-designed their WRX lightweight pulley to provide even more benefits. It is now shaped to look exactly like the factory Subaru pulley, so it goes unnoticed in your engine bay - it even uses the factory belts! A significant amount of weight has been removed from around the rim for even better throttle response. The pulley weighs in at 578g (previously 790g), compared to the factory 2180g on the WRX and 2575g on the STI. This pulley will improve throttle response (particularly off-boost response) and allow the engine to rev more freely in the upper rev range.

It suits all Subaru EJ-series engines, and does not require additional belts
