Thumbnail Filmstrip of 7.3 Powerstroke KC300x G3 Stage 1 Conversion Kit (3.5" Metal CCV) KC Turbos 302751 Images
The 1994-1998 Ford 7.3L Powerstroke remains a legend of the diesel world, but its original turbocharger technology has long been the bottleneck for modern performance. The KC Turbos 302751 KC300x G3 Stage 1 Conversion Kit bridges that multi-decade gap, bringing contemporary "SXE" style aerodynamics and structural integrity to the OBS (Old Body Style) platform. This kit is a comprehensive 100% drop-in solution, meaning you can achieve significant, dyno-proven power gains without the need for custom fabrication or permanent vehicle modifications. By integrating a custom outlet flange, pedestal, and up-pipe kit, KC Turbos allows your OBS to utilize a Gen 3 KC300x while retaining your factory downpipe and y-bridge, effectively modernizing your engine's respiratory system through superior engineering.
- Advanced Aerodynamics: Features a Gen 3 7x7 SXE-style compressor wheel with upgraded aero and extended tip technology, paired with a redesigned 0.70AR ported compressor cover for optimized airflow.
- Radical Turbine Redesign: The 0.91AR turbine housing utilizes modern volute technology to outperform older designs; it spools faster than the previous 0.84AR housing and flows more air than the 1.0AR version.
- Reinforced Rotating Assembly: A significantly thicker Gen 3 SXE-style turbine shaft prevents the deflection and catastrophic failures common in stock shafts when pushed to higher boost levels.
- Industrial-Grade Internals: Equipped with journal bearings that are 200% larger than standard, alongside a redesigned bearing housing with an integrated cast iron backing plate for maximum rigidity.
- Thermal and Physical Stability: Includes a steel thrust insert to reinforce the oil slinger and piston seal contact areas, eliminating bearing fatigue and ensuring consistent expansion rates under extreme heat.
- Complete Installation Package: The kit arrives with all necessary gaskets, o-rings, a high-flow non-EBPV outlet flange, and a newly upgraded 3.5-inch intake boot for a perfect, leak-free fit.
- Enhanced Boost Control: A redesigned round-top wastegate actuator provides precise control over boost pressure, ensuring your engine stays within its peak power band longer.
The true value of the KC300x Gen 3 lies in its ability to balance lightning-fast spool-up with massive top-end flow. While traditional upgrades often force a compromise between low-end responsiveness and high-RPM power, the G3’s redesigned volute shapes and anti-surge rings allow for a broader, more usable power curve. The transition from an aluminum backing plate to an integrated cast iron design with a steel thrust insert further ensures that this turbo can withstand the intense pressures of a high-performance diesel environment without the risk of plate deflection. Whether you are towing heavy loads or looking for a more responsive daily driver, this conversion kit provides the reliability of a journal-bearing system with the cutting-edge efficiency of a modern racing turbocharger.
Supports: Up to 205cc/30% injectors
