Overview 

The PSR 6870E Forward Ball Bearing Turbocharger is designed for serious performance applications, capable of supporting up to 1,100 horsepower. It features a dual ball bearing system, which reduces friction for faster spool-up, sharper throttle response, and increased durability. The turbo is equipped with a 68mm billet compressor wheel (with a 92.46mm exducer) utilizing extended tapered tip technology and a 7+7 blade design, delivering high efficiency and excellent airflow. On the turbine side, it uses a 10-blade Inconel 713C turbine wheel, built to withstand extreme heat in high-boost environments. The compressor housing supports a 4.0-inch inlet and 2.5-inch outlet, ensuring strong flow potential, while the 1.0 A/R T4 divided turbine housing with a 3-inch V-band outlet allows for efficient exhaust flow and easy installation. It also includes a 0.9mm internal oil restrictor, eliminating the need for an external one, and uses a 1/8-27 NPSF oil feed fitting. For added convenience and secure installation, a V-band flange kit is included. This turbo is ideal for street, drag, or track applications where fast spool and big power are critical.
