KC Turbos KC300x G3 Stage 2 Turbo 99.5-03 Ford 7.3L PowerstrokeThe KC300x Stage 2 Gen 3 Turbo is a high performance, drop in upgrade for 7. 3L Powerstroke pickup trucks running larger injectors and higher horsepower goals. Designed through years of R&D and extensive dyno testing, this Gen 3 turbo delivers faster spool, increased airflow, and improved durability over previous KC300x designs and competing drop in turbos.

The KC300x Stage 2 Gen 3 Turbo is a high-performance, drop-in upgrade for 7.3L Powerstroke pickup trucks running larger injectors and higher horsepower goals. Designed through years of R&D and extensive dyno testing, this Gen 3 turbo delivers faster spool, increased airflow, and improved durability over previous KC300x designs and competing drop-in turbos.

At the core of the Stage 2 is a redesigned Gen 3 7x7 SXE-style compressor wheel with upgraded aerodynamics and extended-tip technology, paired with a thick-shaft SXE-style turbine wheel built to handle higher boost and horsepower levels. The modern 0.70 A/R ported compressor cover and redesigned 0.91 A/R turbine housing utilize advanced volute geometry, an improved MAP groove, and an anti-surge design to spool faster than older 0.84 A/R housings while flowing more air than previous 1.0 A/R setups. Delivering strong low-end response with excellent top-end power.

Reliability is a major focus of the Gen 3 platform. This turbo features 200% larger thrust and journal bearings, a thicker turbine shaft to prevent deflection, and a redesigned bearing housing with an integrated cast-iron backing plate for increased rigidity under extreme heat and pressure. A steel thrust insert further reinforces critical wear areas, eliminating common failure points found in stock and earlier turbo designs.

The KC300x Stage 2 installs as a 100% drop-in replacement for 7.3L Powerstroke pickup trucks and includes all required gaskets, O-rings, and an upgraded 4" intake boot for improved fitment. A high-flow non-EBPV outlet flange improves exhaust flow, while the redesigned round-top wastegate actuator provides more consistent boost control.

This turbo is recommended for trucks running 205/30 through 238/80 injectors, making it ideal for aggressive street, towing, and performance builds that demand maximum drop-in power. For smaller injector setups, the KC300x Gen 3 Stage 1 is the better match.
