APR 2.0T FSI Stage III GTX Turbocharger System

Building upon over a decade’s worth of experience with turbocharged Audi and VW engines, including over half a decade with direct injected engines, APR’s Engineers have taken the 2.0T FSI to ground breaking levels of performance without compromise.

APR is pleased to introduce the 2.0T FSI Stage III GTX Turbocharger System. Producing over 405 horsepower on 93 (R+M)/2 octane and 449 HP in racing configurations, Stage III GTX places the 2.0T FSI's accelerative performance in the same league as that of large V8 supercharged muscle cars and sub $400,000 exotic sports cars.

The new APR Stage III GTX Turbocharger System represents a large leap in technology over our previously available GT Turbocharger System. The new system’s response is much quicker, spooling hundreds of RPM sooner thanks to the latest in Garrett turbocharger technology and advancements in the ECU Upgrade. Further refinement of the fueling system increases the vehicle's reliability and drivability to levels only matched by the OEM. A substantial increase in horsepower and torque results in roughly a 30-50 HP gain in the area under the curve over the previous system. As you hear a new exotic growl from your exhaust system, expect exhilarating g-force levels sure to put a huge grin on your face!

At the heart of Stage III GTX is a GTX2867R turbocharger, consisting of the latest technologies from Le Mans’ winning turbo manufacturer, Garrett Honeywell. The internally gated unit features a fully-machined, ten-blade billet compressor wheel and a dual ball bearing oil and water-cooled CHRA. APR’s Engineers spent countless hours testing turbine inlet and A/R sizes in order to decrease turbocharger lag without negatively impacting peak power. The newly developed compressor housing utilizes anti-surge porting, which greatly complements the lightning fast spool characteristics of this unit and grants APR’s Engineers the ability to deliver massive levels of torque inducing boost pressure, even in the lower RPM range.

Each turbocharger unit is assembled and clocked in house at APR with the necessary brackets to ensure proper wastegate fitment and orientation. Each wastegate is then calibrated for precise operation and control to ensure seamless integration with the expertly recalibrated OEM engine management system.
