Overview
The APR GTS K04.3 Turbocharger System upgrades the Porsche 991.2 911 3.0T to the larger factory-spec GTS turbochargers and includes an APR Stage 3 ECU Upgrade calibrated specifically for the conversion. The result is a plug-and-play turbocharger upgrade capable of producing up to 615 HP and 549 ft-lbs of torque on the factory engine hardware, fueling, intercoolers, and emissions components.
With upgraded intercoolers, output increases to as much as 648 HP. Depending on the factory engine configuration, APR reports gains of up to +263 HP and +266 ft-lbs of torque over the base engine and up to +244 HP and +223 ft-lbs over the S engine.
The system includes two genuine BorgWarner K04.3 turbochargers, along with the required gaskets and O-rings for installation. The turbochargers are designed as a direct replacement for the factory units, allowing the GTS-style turbo configuration to be installed without requiring additional engine or fueling hardware.
The 3.0T platform shares the majority of its supporting components across the base, S, and GTS models, making the GTS turbo conversion a straightforward upgrade. The system retains the factory engine hardware, fueling system, and emissions components and is also compatible with supporting engine and exhaust upgrades.
An APR Stage 3 ECU Upgrade is included with the system and is programmed directly to the vehicle's factory ECU at no additional charge. The calibration is designed around the larger K04.3 turbochargers and allows the factory vehicle hardware to take full advantage of the increased airflow and performance potential.
For customers looking for a substantial power increase without converting the vehicle to a fully built engine or aftermarket fueling system, the APR GTS K04.3 Turbocharger System provides a complete turbocharger and calibration package using genuine OEM-based components.
