Overview 

The PSR 5455G DBB Forward Turbocharger is a high-performance unit rated to support up to 660 horsepower. It features a dual ceramic ball bearing system for quicker spool-up and enhanced durability. The turbo is equipped with a 9-blade G-Aero billet compressor wheel designed with extended tapered tips for improved airflow and throttle response. On the turbine side, it uses a 9-blade Inconel 713C wheel for exceptional heat resistance and strength. The compressor housing is a T51R-modified forward rotation design, paired with a 0.83 A/R T3 open inlet turbine housing that includes a V-band outlet for easy exhaust connection and compact fitment. It also features integrated ports for oil and water cooling, along with an internally wastegated billet actuator for precise boost control, making it suitable for aggressive street and race applications.
