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 Golf R and S3 to ground breaking levels of performance without compromise.

APR is pleased to introduce the Golf R and S3 Stage III Turbocharger System. Producing over 460 horsepower in racing configurations with nearly no increase in turbocharger lag over the vehicle’s factory setup, Stage III places the Golf R's and S3’s accelerative performance in the same league as that of large V8 supercharged muscle cars and sub $400,000 exotic sports cars. Thanks to the Golf R's and S3’s all-wheel drive system, power delivery is unlike anything previously experienced in standard form. 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!

Turbocharger

At the heart of Stage III 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.

Motul Oil, Coolant and Oil Filter

Part of the APR Turbocharger System install process requires removal of the OEM Turbocharger. During this process, oil and coolant must be drained and should be replaced to offer superior performance and protection. The APR Turbocharger Systems are now complete turn key solutions, including everything you need down to the oil, coolant and oil filter. During checkout you'll be given the option between Motul Specific 502.00, 505.00 & 505.01 5W40 or Motul Power 300V engine oil as well as Motul Inugel Optimal Ultra Coolant and an OEM oil filter. The Premium Motul lubricant package is included at a much lower than retail price point and the costs are listed below.

 APR's sole mission is to engineer only the highest quality tuning solutions for Volkswagen, Audi and Porsche vehicles.
