KC Turbos KC300x G3 Stage 3 Turbo 99.5-03 Ford 7.3L Powerstroke

Unlock serious performance from your 1999.5-2003 Ford 7.3L Powerstroke with the KC Turbos KC300x Gen 3 Stage 3 Turbo. Designed for higher horsepower builds, this drop-in turbocharger delivers increased airflow, stronger top-end power, and improved durability over stock and lower-stage upgrades. Whether you're running larger injectors or building a more aggressive setup, the KC300x Stage 3 is built to support your goals. The Gen 3 KC300x features a fully redesigned compressor and turbine housing system inspired by modern turbocharger technology. A ported anti-surge compressor cover improves airflow and surge resistance, while the upgraded bearing housing supports larger thrust and journal bearings for enhanced reliability under high boost and heat conditions. This turbo is equipped with a .91 A/R turbine housing and a 0.70 A/R compressor cover. It is important to note that A/R (Area/Radius ratio) is typically used to describe the turbine housing only, which controls exhaust flow and spool characteristics. In this case, the .91 A/R refers to the turbine housing, while the 0.70 A/R refers to the compressor cover, highlighting the updated intake-side design. This combination helps balance top-end power with improved airflow efficiency. As a true drop-in turbo, the KC300x Gen 3 Stage 3 installs in place of the factory turbocharger without requiring major modifications, making it an excellent upgrade for performance-focused 7.3L owners looking for reliable power gains.
