The APR Stage 3 PowerMax GT2563S Turbocharger System for the MK8 Golf R / S3 / Arteon Platform is a direct bolt-on upgrade that includes a Garrett turbocharger, installation kit, and APR software upgrade. This system delivers an impressive 478-543 HP and 409-435 FBLBS of torque, depending on octane level. Designed to maximize power with just an intake and intercooler, it requires no additional hardware.

The Garrett PowerMax GT2563S Turbocharger provides a 20% increase in compressor flow and a 37% increase in turbine flow compared to the factory Continental turbocharger, all within a direct replacement bolt-on package. The turbine wheel, made from a Mar-M alloy rated for 1050C, ensures the system can operate under extreme conditions without compromising reliability.

The kit includes an upgrade to APR Stage 3 software from a lower stage, designed to achieve the specified power levels with only the intake and intercooler system. There is no need for additional, costly, or emissions-impacting exhaust systems, fueling modifications, or sensors at this power level.

The horsepower and torque gains achieved with this turbocharger upgrade are substantial. APR’s calibration engineering experts dedicated months to fine-tuning the Stage 3 Pmax engine and transmission software to provide an exceptional driving experience without imposing undue risk on your engine’s lifespan. Reliability is a core principle of the APR experience and was a paramount design requirement for our engineering team.

The software is available in both high and low torque configurations to respect transmission limits when additional upgrades, such as our Stage 3 TCU upgrade, are not feasible. While the turbocharger is capable of higher low-end torque, prioritizing engine reliability necessitates discipline. Our software delivers a smooth, linear torque curve across both configurations and various octane levels, ensuring an exhilarating drive without placing undue stress on engine components.

In designing this upgrade, our team meticulously adhered to Garrett’s prescribed specifications for turbocharger reliability, including exhaust gas temperature and turbocharger shaft speed limits. Additionally, the software is calibrated to operate within the limits of factory sensors and fueling hardware, delivering a dependable driving experience.

APR’s calibration experts have also integrated additional safety and protection protocols into the ECU to guard against LSPI, knock, turbo shaft speed, exhaust gas temperature, turbo discharge temperature, exhaust back pressure, and fuel system limits. This ensures that drivers can fully enjoy their vehicle’s performance without undue concern for premature component failure. At APR, we enhance the driving experience by delivering performance without compromise!
