APR Stage 3 software was designed with reliability in mind. It's designed to not spike the turbo hard in the lower RPM band or run on the edge of what the factory rods and pistons have been known to handle. Particular attention was paid toward component protections, for exhaust gas temperature (EGT), back pressure safety (EMAP), turbocharger discharge temperatures, and fueling system capabilities. This was done through accurately adjusting the factory modeling during the development phase. As the need for more fuel increases through rising exhaust gas temperature, the system will lower lambda to cool EGT, but will not excessively tax the injection system with excessive on-times. Secondary protections will limit output for safety. By using our HPFP software headroom is increased significantly, but does so without overdriving the pressure to the injection system. The need for limiting power under extreme prolonged use (Tracking the vehicle for example), is greatly reduced. Lastly, with the upgraded HPFP, output on ethanol is dramatically increased whereas on the stock HPFP Ethanol makes similar power to pump fuel.

Description_INV | B9 S4/S5 DROP-IN TURBOCHARGER KIT |
Description_ASC | This kit includes a 1 year product only warranty (not returns) for manufacturers defects only. Kit must be running APR software with a correct hardware configuration. Specific software is required to use this system. Software upgrade from lower stage is included for various vehicles. Software compatibility must be checked before purchase! The software installs to your vehicle's factory ECU. Currently software can only be installed by an Authorized APR dealer. Software is available in two formats: For use with the stock HPFP, and for use with the APR HPFP. The advertised results were captured with an APR Intake System, APR Intercooler System, and APR TCU Upgrade (for higher RPM). The max output on E85 was produced using an APR HPFP. INCLUDED SOFTWARE POLICY: This kit includes an upgrade to the APR Stage 3 ECU at no additional charge if the vehicle is already tuned with an APR ECU Upgrade. If the vehicle is not, an APR Stage 1 ECU Upgrade must be purchased to get the free upgrade to APR Stage 3 ECU Upgrade. Factory 10,000 mile oil intervals are excessive. Cut oil intervals in half. To add an additional layer of protection, use a high performance oil matching the factory weight and minimum factory specs. Reuse your factory DV. DV not included. |
Description_DES | APR DTR8868 Direct Replacement Turbo Charger System (3.0T EA839) |
Description_EXT | Fits Audi S4 18-24, S5 18-24, S5 Sportback 18-24, SQ5 18-24, SQ5 Sportback 21-24 |
Description_MKT | The APR DTR8868 is a direct turbocharger replacement for the 3.0T EA839 engine found on the 2018+ Audi S4, S5, and SQ5! This upgrade includes matching software for various vehicles and mods, and provides up to 620 HP (571 AWHP) and 622 FT-LBS (572 AWTQ) of torque all while keeping emissions components unmodified. The software supports premium pump fuel grades, race fuel grades, and even ethanol all without any fueling upgrades. Additional HPFP software is available for max output on ethanol and increased protection headroom on pump fuel. Lastly, for dedicated race cars the turbocharger is designed with headroom to go even further on your own! |
Description_MKT | 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. |
Description_MKT | 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 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 88mm compressor wheel. |
Description_MKT | 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 an abuse seen on a road course. The turbine A/R is matched to our new nickel-based superalloy K418 68mm 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. |
Description_MKT | Each kit includes the complete turbocharger including a calibrated wastegate actuator and diverter valve. All necessary one time use install hardware is included. The kit even includes an adapter for the APR intake system to provide maximum flow through the system, though the system remains compatible with the factory intake. |
Description_MKT | Our turbo loyalty program includes a free upgrade from any lower APR ECU stage to Stage 3. If you don't have APR software already, it's just the cost of the Stage 1 tune. Furthermore, there's no charge to upgrade from the stock HPFP software to the upgraded HPFP file, and there's no charge to jump between octanes, including ethanol. |
