Available in a range of 6 turbocharger power output sizes, APR the Subaru performance specialist provides bullet proof turbos for your 2.0l-2.5l

Finally, a range of high performance direct replacement turbochargers that have been specifically designed for the Subaru WRX/STI by the Subaru performance specialists – APS.

APS has designed and produced what is arguably the ultimate in bullet proof turbochargers for the Subaru Impreza enthusiast.

Unencumbered by the limitations of current off the shelf WRX turbochargers, APS has totally engineered a “no-compromise” series of turbochargers from the ground up to match the exact requirements of high performance Subaru Impreza engines.

High strength compressor wheel design, ball bearing construction and high nickel content turbine housing means complete reliability to pressure ratios over 3:1 (30 psi!). And since nobody likes to wait, the APS S/R Series turbochargers are designed for fast spool-up to provide crisp turbocharger response.

Best of all, the S/R range of turbochargers are complete bolt on. Simple hook up of all factory connections and full compatibility with high performance inlet/exhaust means that the installation of your APS S/R Series turbocharger is truly no hassle.

If you want ballistic power and outstanding turbocharger reliability in a truly bolt on high performance unit, then the APS S/R Series turbocharger the perfect choice.

Available in a range of 6 turbocharger power output sizes to over 500 hp (370 kW), APS provides an S/R Series turbocharger that is optimum for engines from mild 2.0L through to wild 2.5L. The APS S/R Series Turbochargers are complete with all ancillary equipment for a truly bolt-on performance upgrade to the Subaru WRX/STI.

The APS SR30 turbocharger is an ideal turbocharger for the person who is chasing impeccable driveability as well as significantly improved power and torque – with the capacity to produce up to 340 hp. The SR30 also offers a very broad range of operation at high efficiency values.

You have spent thousands of dollars modifying your car from cold air intakes to exhausts and everything in between.  You will not see your car’s full potential leaving its computer as-is.

The factory computer system is set up to monitor the engines fuel/air ratio as a stock non-mod car.  When you highly modify your car you really need a way to reprogram the Engine Management System (ECU) on the go whether you need boost control, drive Ignition, Idle control or Fuel/Air mixture control.

Widow Racing recommends the AEM Universal EMS ECU.  This system adapts to any vehicle.

AEM Universal EMS ECU

The success of our Plug & Play EMS program created a demand for a universal unit, and AEM is proud to release its Universal Programmable EMS. AEM Universal Programmable Engine Management System adapts to any vehicle using the company flying lead wiring harness and sensors (sold separately). We are confident that this is the most versatile, powerful, and comprehensive universal engine management program available.

In addition the features found in our Plug & Play EMS, AEM Universal EMS also includes 10 independent, built-in peak & hold injector driver channels, direct drive ignition and dual wideband UEGO controllers. Peak & Hold injector drivers enable users to utilize low impedance injectors with a true 4/1 Peak & Hold injector drive circuit. The Direct Drive ignition feature allows users to drive a coil directly from the ECU without the need for an igniter or ignition module. A wideband UEGO controller is an essential tuning tool that provides a 0-5 signal for monitoring and tuning air/fuel ratios (AFR) on heavily modified high-performance engines.

Key features include:

If you literally want to get a jump on the competition you have to get a short shifter.  A short shifter is designed to reduce the throw between gears, which enables you to have smoother and faster shifts.

I recommend Agency Power for your WRX/STI or for any other tuner car.

Agency Power has released their incredible 2008+ Subaru WRX 5 speed short shifter. The shifter is made from 6061 aluminum that is CNC machined for a smooth finish and precise fit. The bottom ball is increased in diameter from the previous 02-07 year cars. The factory bushings fit in the center part of the shifter to connect the shift linkage. The aluminum top is threaded to fit the stock or aftermarket shift knobs. The shifter has a reduction in throw as well as about a drop of 1 inch in height. This provides precise and quick shifts for the track or street. The Agency Power Subaru WRX 5 Speed Short Shifters are available in anodized red color.
