See Emissions Details
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, we had complete control over the design. We've 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 our larger billet aircraft-grade 6061 aluminum 60mm compressor wheel. We've 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. We've 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 our 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 our 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. 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 our ECU Upgrades for select vehicles. 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. 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. Go APR!

This part is legal under the provisions of EPA’s Tampering Policy dated November 23rd, 2020. The company has reasonable basis (test results) to verify that this product allows the vehicle to operate within legal emissions standards and is therefore legal to be sold for on-street use in all states that accept the legal provisions of the Clean Air Act and the EPA Tampering Policy. This product is NOT LEGAL FOR SALE OR USE IN THE STATE OF CALIFORNIA. Testing with the California Air Resources Board, in order to achieve 50-state compliance, is pending with CARB. Once testing is complete with California, and an E.O. number is issued, this product will be updated to 50-state legal status.
Specific software is required to use this system. Software is included for various vehicles. Software compatibility must be checked before purchase. If no software is found, a software request must be made and filled before purchase. Please contact an importer for support and application guides outside the USA. Software is available in three formats: - For use with stock fueling (T4100003) - - 91 AKI, 93 AKI, 100 AKI, & 104 AKI - - 95 RON, 98 RON, 104 RON, & 108 RON - For use with an APR HPFP and APR LPFP (T4100003-A) (Golf R/S3/TT S Platform Only) - - 91 AKI, 93 AKI, 100 AKI, 104 AKI, & E85 - For use with an APR HPFP, APR LPFP, and APR MPI Injectors (T4100003-B) (Golf R/S3/TT S Platform Only) - - 91 AKI, 93 AKI, 100 AKI, 104 AKI, & E85 GTI/A3/TT platform ECUs have an optional Front Wheel Drive (FWD) file that will limit wheel spin by limiting how torque hits. Any FWD car can choose to run the All Wheel Drive (AWD) file to remove this feature. The software installs to your vehicle's factory ECU. Software can only be installed by an Authorized APR dealer. 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 APR or 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). This kit includes a 1 year warranty (not returns) for manufacturers defects only. Kit must be running APR software with a correct hardware configuration.

Have a question about this product?

  • Question

    Can I use with downpipe decatted?

    By Alejandro Gonzalez on February 6, 2023

    We only wrote software for the factory catalyst to remain emissions compliant.
  • Question

    What is the latest estimate on CARB approval date for those of us stuck in California?

    By Michael Webb on February 5, 2023

    We can't speculate unfortunately. It's a very long process at times that's mostly out of our control.
  • Question

    Is this compatible with stock feeling on the 2019 Golf R or am I required to do high pressure fuel pump and or low pressure fuel pump with or without MPI?

    By Jo Bangles on February 7, 2023

    It's compatible with the stock fueling. If you want more power, you can add the fueling systems.

Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.
