GFB Non-Underdrive Crank Pulley 94+ WRX/STI 98+ Forester 98+ Liberty
Regular price $205.00 Save $-205.00GFB 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

A true ethanol and petroleum friendly fuel pump with flow/pressure capabilities to deliver fuel for up to 350kw at the wheels.
Note: Modifications to the factory fuel pump carrier bracket or module are required.
Our Extreme 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.
You can also choose to add a one way check valve if you prefer:
Note: In place of the BR540 on its own we recommend a Boxer Performance Parts 700HP Subaru Fuel Pump Module for MY08-MY14 WRX, MY08-MY20 STI, MY08-MY13 XT Forester, MY04-MY10 GT Liberty.

Pierburg 3 Port Boost Solenoid Subaru Universal
Regular price $148.95 Save $-148.95Unlike the factory solenoid,this 3-Port Solenoid allows you to raise the factory boost levels with more response and adding more control.
With this solenoid no boost pressure is allowed through to the actuator so no premature boost can occur. The 3-Port Solenoid allows lower wastegate duty cycle to produce higher boost pressures with much greater control,thereby allowing tuners more “headroom” and “space” when modifying high horsepower turbo vehicles.
The kit includes the 3-Port Boost Control Solenoid and harness for plug and play install with Subaru models. We recommend using it only with hoses of the highest quality.
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!
