Unlock serious gains on your Gen 1 F-Series B58 with the Pure 800 cast-housing hybrid. This is a brand new stock-location performance turbo supplied outright with no core charge and no exchange. It drops straight in, keeps factory lines and the OEM downpipe connection, and comes with a high-flow silicone intake for maximum airflow and fast response.

Developed by Pure Turbos and precision VSR balanced, this setup is built to deliver rapid spool, huge mid-range punch and relentless top-end. With the right supporting hardware, calibration and fuel, customers consistently see power figures deep into the 600s and beyond while retaining daily-drive manners.
