"Convert your Subie into a giant killer! Monstrous power and torque whilst retaining great on road manners."

The Subaru WRX/STi 01-05 Type3 upgrade starts with our trained technician fitting a cold air intake and high flow air filter, a 430hp capable TD05-18XT Billet wheel turbocharger, a Process West top mounted intercooler, upgraded fuel injectors (for WRX), a walbro fuel pump and finally a stainless steel 3″ turbo back exhaust system and catless up-pipe if required, we then tune your vehicle’s ECU on the dyno in real time utilizing the latest Subaru ECU tuning software to maximize power, torque and fuel efficiency. We complete the upgrade process by testing your vehicle on the road to make final adjustments, optimizing your vehicles performance and driveability. At the end of this upgrade we will provide you with a dyno graph comparing the ‘before’ power & torque and the ‘after’ increase the HPF Subaru WRX/STi 01-05 Type3 upgrade has made to your vehicle.

Like all HPF upgrade packages the Type3 package is modular in that it allows the customer to add to the package minimising the requirement to spend money twice when and if further upgrades are desired. HPF strive to bring you maximum performance with high quality components while still maintaining reliability and driveability.
