898199-5001W GARRETT 485HP TURBO FOR VW/AUDI 2.0L TSI MK7 (IS38)



VAG 2.0L TSI MK7 PowerMax - Stage 1

Garrett PowerMax™ turbocharger upgrades for the Volkswagen and Audi MK7 2.0L TSI engine platform is engineered to increase engine performance while maintaining OEM installation specifications. Stage 1 (485 BHP*) and Stage 2 (600 BHP*) upgrades maximize efficiency and air flow compared to the OEM turbocharger. High temperature, Mar-M alloy turbine wheel and twin scroll stainless steel turbine housings are rated for up to 1050° C. These turbochargers are fully assembled with a calibrated electronic actuator and ancillary components for direct OEM fitment. WARNING: Maximum allowable turbocharger speed is 185krpm (Stage 1) | 165krpm (Stage 2). The use of this product above max turbocharger speed is at the owner’s risk, and can result in damage and premature failure. To protect the turbocharger from overspeed when operating, a speed sensor port is machined into the compressor housing for the fitment of speed sensor part numbers 781328-0003 (includes sensor and gauge), and 781328-0004 (includes speed sensor). Speed sensors sold separately.
