This turbo features an advanced 64mm billet compressor wheel and a 66mm high-flow 10-blade turbine designed to improve power, spool-up, cooling, and towing capability. Whether you daily drive, tow, or want a stronger street setup, the Stage 2 balances drivability with top-end performance and EGT control.\u003c\/p\u003e\n\u003cp\u003eKC Turbos engineered this unit using precision point-milled machining, upgraded 360° thrust bearings, and a redesigned turbine for faster response and increased airflow.
