For more information, visit www.P65warnings.ca.gov.The APR K04.3 GTS Turbocharger System (T2100084) is a comprehensive performance transformation for Porsche 911 (991.2) 3.0T owners. This system converts Base, T, and S models to the larger factory GTS-spec turbochargers, effectively mirroring the Porsche "X51" Powerkit but with significantly enhanced tuning. The result is a staggering increase in output, delivering up to 615 HP and 549 FT-LBS of torque on otherwise stock hardware, and up to 648 HP when paired with upgraded intercoolers.
Because the 3.0T engine architecture is largely shared across the 991.2 Carrera range, this conversion remains highly reliable and emissions-compliant. The kit uses Genuine BorgWarner K04.3 Turbochargers and authentic Porsche gaskets, ensuring a perfect factory fit. To manage the increased airflow, the system includes the APR Stage 3 ECU Upgrade, which provides the sophisticated calibration required to turn these larger turbos into a seamless, plug-and-play power increase that eclipses the output of a factory GTS.
Features:
- GTS Power Conversion: Upgrades Base (370HP) and S (420HP) models to the larger GTS-spec turbocharger architecture.
- Massive Power Gains: Gains of up to +263 HP and +266 FT-LBS over a stock base engine.
- Genuine OEM Hardware: Includes two brand-new BorgWarner K04.3 turbochargers and genuine Porsche gaskets/O-rings for factory-level longevity.
- Stage 3 Software Included: Comes with the APR Stage 3 ECU Upgrade (must be installed by an authorized APR dealer).
- OEM Integration: Fully compatible with factory fueling, cooling, and emissions systems; no custom fabrication required.
- Scalable Performance: Works seamlessly with additional bolt-on upgrades like high-flow intercoolers and exhaust systems.
