This XR1 Series HE351VGT Turbocharger comes with an upgraded Billet Blade Technology 63mm compressor wheel. The Billet Blade Technology compressor wheel is designed to increase turbo efficiency to help lower EGT\'s while adding strength and reliability. Because of the high failure rates with Remanufactured Turbochargers, we are proud to use only 100% BRAND NEW turbos direct from the manufacturer. This ensures more reliability and longevity than any other competitor on the market.
