KC Turbos KC300x G3 Stage 1 Turbo 99.5-03 Ford 7.3L Powerstroke
The KC300x Stage 1 Gen 3 Turbo is a true drop-in performance upgrade for the 7.3L Powerstroke, delivering faster spool, increased airflow, and proven power gains without sacrificing reliability. Developed through years of R&D and dyno testing, this Gen 3 design outperforms previous KC300x versions and other drop-in turbos on the market.
At the core is a redesigned Gen 3 7x7 SXE-style compressor wheel with upgraded aerodynamics, paired with a thick-shaft SXE-style turbine wheel built to handle higher boost levels with improved durability. The modern 0.70 A/R ported compressor cover and 0.91 A/R turbine housing feature advanced volute geometry, an improved MAP groove, and anti-surge design. Allowing the turbo to spool faster than older 0.84 A/R housings while flowing more air than previous 1.0 A/R designs. The result is stronger low-end response with improved top-end power.
Reliability is significantly enhanced with 200% larger thrust and journal bearings, a thicker turbine shaft to reduce 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, addressing common failure points found in stock turbochargers.
This turbo installs as a 100% drop-in replacement, requiring no modifications. It includes all necessary gaskets, O-rings, and an upgraded 4" intake boot for improved fitment. A redesigned round-top wastegate actuator improves boost control, while the high-flow non-EBPV outlet flange enhances exhaust flow.
The KC300x Stage 1 Gen 3 is well suited for daily driving, towing, and performance-oriented builds seeking maximum power from a true drop-in turbocharger.
FEATURES & BENEFITS:
- 100% drop-in turbocharger (no modifications required)
- Dyno-proven power gains
- Gen 3 7x7 SXE-style compressor wheel with upgraded aerodynamics
- Thick-shaft SXE-style turbine wheel
- 0.70 A/R ported compressor cover with anti-surge design
- 0.91 A/R turbine housing with modern volute technology
- Faster spool and increased airflow over previous designs
- 200% larger thrust and journal bearings
- Redesigned bearing housing with integrated cast-iron backing plate
- Steel thrust insert for improved durability
- High-flow non-EBPV outlet flange
- Round-top wastegate actuator for improved boost control
- Includes all required gaskets, O-rings, and upgraded 4" intake boot
FITMENT NOTES:
- Designed for 7.3L Powerstroke pickup trucks
- Will not fit OBS or E99 trucks without modification
- Fitment with aftermarket fuel systems, plenums, or piping kits is not guaranteed
ADDITIONAL NOTES:
- Exhaust brake compatibility varies by manufacturer and must be verified by the customer
