For more information, visit www.P65warnings.ca.gov.The APR Stage 3 DTR8563 Turbocharger System (T4100004) is a revolutionary performance upgrade for the Audi 2.5 TFSI EA855 EVO engine found in the RS3 and TT RS. This system redefines the Stage 3 experience by delivering supercar-level power—up to 672 HP and 544 FT-LBS of torque—without the requirement for expensive engine internals, fueling modifications, or exhaust changes. Engineered as a direct bolt-on solution, the DTR8563 provides brutal acceleration and a relentless climb to a 7,500 RPM redline while remaining street-legal and emissions-compliant.
The heart of the system is a precision-engineered turbocharger featuring a dual ceramic ball-bearing center section and a billet 6061 aluminum compressor wheel with an integrated anti-surge cover. The turbine side utilizes a K418 nickel-based superalloy wheel housed in a 310 stainless steel casing, rated for extreme temperatures. This hardware is paired with APR’s world-class Stage 3 ECU and TCU calibrations, which include built-in safety routines to protect the engine at high output levels while providing a refined driving experience for the street.
