Overview
The APR GTS K04.3 Turbocharger System converts your 991.2 911 3.0T to the larger factory GTS turbochargers and includes our Stage 3 ECU Upgrade making the conversion plug-and-play! Up-to 615 HP and 549 FT-LBS of torque is available with no other modifications. Adding upgraded intercoolers bumps power up to 648 HP. This is a substantial increase in power and torque. Expect up to an additional +263 HP and +266 FT-LBS over stock on the base engine, and +244 HP and +223 FT-LBS on the S engine!
This conversion system, sometimes dubbed an x51 package by Porsche, includes all genuine parts. It includes two new and genuine Borg Warner K04.3 Turbochargers, new gaskets, and o-rings. Simply remove and replace the factory components with our new components. No other hardware upgrades are required as the 3.0T mostly shares the same components, except for the turbochargers, from the base model to the GTS model. This system works with your factory engine hardware, factory fueling, and factory emissions components. It even works with upgraded engine and exhaust components and picks up even more power with upgraded intercoolers! This is all made possible by the included world-class APR Stage 3 ECU Upgrade (from any lower stage) which is programmed to your factory ECU at no additional charge!
