APR T4100001 Features:

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!

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 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.

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.

Notes:

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.
