The APR DTR6054 is a direct turbocharger replacement for the EA888 Gen 3 Engine. This upgrade includes matching software for various vehicles and mods, and provides up to 491 HP and 425 FT-LBS of torque, depending on vehicle platform and fueling, all while keeping emissions components unmodified. The software supports premium pump fuel grades, race fuel grades, and even Ethanol on the Golf R, S3 and TT S platform with fueling upgrades! For dedicated race cars the turbocharger is designed with plenty of headroom to go even further on your own!

This is a brand new turbo designed and developed by APR from the ground up. It does not require a core, and there's no additional downtime associated with other upgrade styles. The turbo bolts to the factory location and connects to factory or upgraded components.

Since this turbo was designed from the ground up, and doesn't use any of the factory or factory cloned housings or internals, APR had complete control over the design. They upgraded the CHRA to feature German dual ceramic ball-bearings for smooth and reliable operation with better transient response. This also does away with the failure-prone journal bearing design on the factory turbochargers. Next the compressor cover was upgraded with an appropriate A/R matched to APR's larger billet aircraft-grade 6061 aluminum 60mm compressor wheel. APR also included a large turbo inlet pipe that perfectly matches the turbo's anti-surge compressor cover and connects directly to your factory or upgraded intake system. They have completely done away with the turbo muffler assembly providing the turbo with a larger outlet and smoother transition. The compressor cover even includes a port for a turbocharger shaft speed sensor should one suit your build.

The turbine side of the turbocharger also benefits from APR's ground-up design. The turbine housing is cast with 310 stainless steel that's designed to take the heat and abuse seen on a road course. The turbine A/R is perfectly matched to their new nickel-based superalloy K418 54mm turbine wheel. The system will see low exhaust gas temperature, low exhaust back pressure, low turbo discharge temperature, and low shaft speeds because the system has been properly designed from the ground up for the prescribed power levels. Of course, each rotating group is VSR balanced for reliable operation. This all lends well for customers who plan to use this turbo on a dedicated race car as it has the headroom necessary to push the system further on their own.

The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 37% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances.

The APR Low Pressure Fueling System is a comprehensive upgrade required to safely support Stage 3+ power levels. The upgrade includes a larger in-tank low pressure fuel pump (LPFP) which is also ethanol compatible. All necessary hardware is included for a seamless integration and the system is fully controlled by the factory engine control unit (ECU) thanks to APR's ECU Upgrade.

This system has seen many road course track days and extensive testing to ensure longevity and reliability of the setup in the harshest of conditions. This setup does not spike torque hard or run on the edge of what the factory rods and pistons have been known to handle, making it as safe on the stock engine as we can for these power levels.

APR T4100003-A Manufacturing:
The DTR6054 turbine housing is cast with 310 stainless steel. The CHRA features German dual ceramic ball-bearings and the 60mm compressor wheel is made from billet aircraft-grade 6061 aluminum while The 54mm turbine wheel is made from a new nickel-based superalloy. Each rotating group is VSR balanced. Each kit includes the complete turbocharger with compressor inlet pipe, compressor outlet hose, t-bolt clamps, gaskets, o-rings, exhaust ring, exhaust v-band, exhaust manifold gasket, new studs, bolts, and washers, all new oil and coolant line o-rings, and includes an APR ECU Upgrade. The upgrade uses your factory electronic wastegate and diverter valve, and connects to your factory exhaust, intake, turbo outlet pipe, and oil and coolant lines.

APR T4100003-A Installation

This system reuses your factory electronic wastegate and electronic diverter valve. To safely achieve the advertised power use an upgraded Intake and Intercooler. To prevent clutch slip use our transmission software or a manual clutch upgrade. Use NGK heat range 9 (NGK-R7437-9) 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. Always use a high performance oil with more frequent change intervals. To fit this system with APR Compressor Outlet Pipes, use the APR DTR6054 Compressor Outlet Hose Conversion Kit (MS100213).
