Genuine Subaru Valve Cover Oil Separator LH

Genuine Subaru Camshaft Bolt Non-AVCS

MAC 35 series are the go-to solenoid valve for automotive boost control due to their exceptionally rugged and reliable design. Features waterproof female connector, 1/8″ BSP threads, and includes two 7mm hose tails.

Tuning Notes:

Because this upgraded solenoid affects the way that your vehicle controls boost, it is always recommended that you consult with a tuner immediately following installation. It is not recommended that you drive the car in a way that builds boost without doing so. If you have any questions, don't hesitate to get in touch with us directly!

Direct Fit High-Output 300L/H Replacement Ethanol Friendly Fuel Pump

A true ethanol and petroleum friendly replacement fuel pump with flow/pressure capabilities to deliver fuel for up to 280kw at the wheels.

We recommend a Boxer Performance Parts In-Tank Fitting Kit for MY94-MY07 Impreza, WRX, STI, Forester + MY94-MY03 Liberty, Outback.

Note: Our High-Output Fuel Pumps do not have a check valve, therefore slightly longer ‘cranking’ periods are experience before the engine ‘fires-up’, this is a positive side-effect for engine longevity.

GSS 39MM Fuel Pump Family Design Update: Generation 3 (G3)

Walbro / TI Automotive has made pump outlet updates to our popular line of 255LPH 39MM Gerotor fuel pumps. The new outlet design is engineered to improve fitting robustness while maintaining the current electrical connection configuration. The update retains our proven pump technology and these third generation pumps will continue to be manufactured in the Caro, MI plant. With the updated outlet design, we will be superseding the current GSS340, GSS341, and GSS342 pumps.

What's Included:

• 1 x GSS352 Fuel Pump Only
• 1 x Installation Fitting Kit

Cylinder 4 cooling has long been a known issue on the EJ Family of Subaru engines. The nature of the water passageways around this area means a lack of cooling can lead to an increase in the temperatures around this cylinder.

RCM's simple solution to this problem lies in our easy to fit complete kit. Billet fittings are banded in place on our custom 90 degree Samco silicon hose, which you simply fit into the unused port at the back of the block at cylinder 4's location. This is then tee'd into the water matrix pipe directly above using the supplied HiGrip stainless steel fittings. The billet barb fitting is of the correct diameter to allow the right flow rate around cylinder 4 to cool without over cooling, and the 90 degree pre-formed Samco hose ensures that this flow is maintained without disturbance from potential kinks in the pipework.

Suits all EJ Engines

The RCM Thermal Gasket kit contains everything required to install our Phenolic Spacers to your Impreza.  

The kit is designed to aid in the reduction of the inlet air temperature, by isolating the inlet manifold from the heat generated by the engine's cylinder heads.  

By reducing the temperature of the inlet manifold, the temperature of the inlet charge is alos reduces.

 The density of cooler is greater than that of warm air, and a denser intake air charge contains more oxygen which results in the potential for increased power and torque.

The RCM 340 uprated fuel pump kit should be one of the first things you consider installing when modifying your Impreza above stock power levels, as the ability to provide your engine with enough fuel is crucial to performance.

The RCM340 is a high output, in tank, electric fuel pump that directly replaces the standard fuel pump assembly within the fuel tank. With the ability to supply an impressive 340 litres per hour of flow, this kit comfortably out performs other Impreza pumps on the market and is a huge improvement on the standard fuel pumps. 

Ideal for Imprezas developing up to 500bhp and with straight forward fitment via the inspection cover on the cars floor pan, the RCM340 offers superior flow throughout a wide pressure range. With unmatched durability and reliability thanks to its turbine pump mechanism and 30% better performance when compared to its rivals, RCM recommends this pump as a great upgrade for the standard unit or even other popular fuel pump kits on the market.

This pump has also been designed to cope with the New Age Imprezas oscillating voltage supply. Feed to the pump varies from 8v to 12v depending on how the car is being driven.

Supplied with all parts required to fit all turbocharged Impreza models.

• 200LPH @ 90PSI | 6.1 Bar
• 250LPH @ 73PSI | 5.0 Bar
• 300LPH @ 55PSI | 3.7 Bar
• 350LPH @ 38PSI | 2.4 Bar

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

Suits:

• 98-00 GT Forester
• 03-04 XT Forester
• 99-00 STI
• 98-03 Liberty GT & B4

Genuine Subaru STI Timing Belt #ST130284S000

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
