For the budget minded individual, APR is pleased to offer software and hardware utilizing an APR proprietary customized version of the factory Borg Warner K04-64 turbocharger. Originally equipped on VAG’s high output models, such as the Golf R and S3, the APR K04 Turbocharger System offers a substantial leap in power and torque all with excellent response in a reliable and stealthy, compact design. Expect lightning fast response, smooth daily driving and power that transforms the vehicle into a new class of enjoyment.

The APR K04 Turbocharger System features many upgrades over the 2.0T’s factory equipped IHI turbocharger, making it an excellent upgrade. The integrated turbofold design features a cast stainless steel exhaust manifold and turbine housing, integrated into one single unit. This design aids in turbocharger spool while the stainless steel construction is capable of withstanding higher exhaust gas temperature for longer periods of time than lesser materials, such as cast iron. The CNC-machined, billet aluminum compressor wheel and higher flow exhaust turbine wheel expand the turbo’s efficiency range, allowing for higher output across a wider RPM range.

True to APR’s mantra of Performance without Compromise the days of shredding tires on front wheel drive vehicles are rapidly disappearing thanks to the new Gold Standard in ECU torque management calibration strategies only APR can deliver. Compressor surge is avoided to increase the reliability of the system without limiting the area under the curve typically experienced during a top speed acceleration run. APR’s endless pursuit of perfection has resulted in the most comprehensive 2.0 TSI K04 turbocharger system and tuning package in the world.

Using 93-octane fuel, the APR K04 Turbocharger System produces an astonishing 360 horsepower and 382 ft-lbs of torque. Unlike the factory turbocharger, power stays strong and doesn’t dramatically taper towards the vehicle’s new 7,100 RPM redline. Switching to APR’s 100 octane race fuel mode, peak power and torque climb further to 375 horsepower and 408 ft-lbs of torque. APR’s calibration experts have safely maximized the full power potential of the turbocharger unit, while keeping reliability at the forefront of their calibration strategies.

 

Requirements and Recommendations

  • Intake System

    APR's software is designed to utilize the factory mass airflow (MAF) sensor and housing. The Carbonio Stage I and II Intake System is highly recommended and required to meet the advertised power output.

  • Exhaust System
    The APR Downpipe Exhaust System is required if the vehicle is not currently equipped with the APR Turboback Exhaust System. APR Recommends the APR Catback Exhaust System for maximum performance.
  • Intercooler System
    The APR Intercooler System is required to meet the advertised power figures.
  • Transmission
    The APR K04 Turbocharger System greatly increases torque over the factory output levels and as such, an upgraded clutch may be necessary to transmit power to the ground. APR highly recommends upgrading the factory clutch to one that suits the operator's intended driving style.
  • Exhaust Valve Springs
    APR has discovered some engines experience exhaust valve float at high RPM at the advertised horsepower levels due to excessive exhaust backpressure caused by K04’s relatively small turbine wheel. In such cases, APR recommends upgrading the factory valve springs. However, upon request, lower output software capable of producing 321 horsepower and 310 ft-lbs of torque on 93 octane is available.
  • Tires
    APR recommends Michelin PSS and PS2 tires as well as BFGoodrich Rivals and GForce Sport Comp 2 tires.
  • Fluids
    APR recommends Motul Fluids and Lubricants.
