APR 2.0 TFSI Valvelift S3 K04 Conversion System - T2100009

« back
Home > Audi > A4 & S4 (B8)

APR's S3 K04 Turbo Conversion is now available for the Audi B8 A4/A5 & Q5 2.0 TFSI Valvelift engine. APR has developed an excellent entry level turbocharger upgrade for the 2.0 TFSI VL engine by incorporating the OEM turbocharger assembly from the Audi S3 and coupling it with APR's expertly recalibrated engine management upgrade. APR's Engineering Team has developed a powerful and reliable turbocharger upgrade that maintains OEM engine bay appearance and offers up to 116 hp and 113 lb ft of torque over the OEM power output of the 2.0 TFSI.

Reliability, drivability, stealth and enhanced performance that cannot be bested are the highlights of APR's newest OEM-component based conversion package.

APR's engineers have expertly recalibrated the engine management system to allow for nearly flat torque delivery from 2800 RPM to 5000 RPM which results in a smooth linear pull throughout the power band. Keeping the track enthusiast in mind, this conversion package will not result in overpowering of the driveline but will allow for smooth acceleration to easily maintain control while cornering.

The Borg Warner K04 turbocharger selected by VAG engineers is perfectly sized for the 2.0 liters of displacement to allow for stout horsepower numbers as the RPMs increase with no dramatic fall off as redline approaches. This ensures plenty of power in the high RPMs for continued acceleration in the straights and positioning at the healthiest portion of the power band after corner exit.

- APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode.
- Max increases are based on APR's actual measured stock values and not those reported by VW. | RON = ROW Fuel Grades | AKI = North American (RON+MON)/2 Fuel Grades.
- Reported wheel figures measured using a Dynapack Dynamometer with a US Spec B8 A4 6MT, using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications.

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
    A high flow downpipe exhaust system is required. APR Recommends a full turboback exhaust system for maximum performance.
  • Intercooler System
    APR highly recommends an upgraded intercooler system 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.
  • Spark Plugs
    APR's software is designed for use with NGK BKR8EIX spark plugs gapped to 0.024" ±0.002" or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km.
  • Tires
    APR recommends Michelin PSS and PS2 tires as well as BFGoodrich Rivals and GForce Sport Comp 2 tires.
