    Supports: Up to 250cc/100% injectors


    Unleash the full potential of your 7.3 Powerstroke engine with the KC300x G3 Stage 3 Turbo, specifically engineered for Early 1999 models. This isn't just an upgrade; it's a complete revolution in turbocharger technology, meticulously redesigned to deliver unparalleled performance and rock-solid reliability. We've spent years in research and development, scrutinizing every weakness of the stock turbo and re-engineering them with modern advancements. The result is a 100% drop-in solution that not only outperforms anything else on the market but also significantly enhances the durability of your truck at elevated horsepower levels. From its quickly spooling design to its robust internal components, the KC300x G3 is built to transform your driving experience, providing more power, quicker response, and long-lasting dependability for the most demanding applications.

    • Optimized Airflow: Features a 4" ported housing with drilled anti-surge and a redesigned Gen 3 7x7 SXE style compressor wheel with extended tip technology and upgraded aero for superior flow and lightning-fast spool.
    • Next-Generation Turbine Design: Equipped with a SXE style turbine wheel with a thicker shaft, housed within a cutting-edge 0.91 AR Turbine housing. This innovative design, inspired by the latest turbochargers, spools up faster and produces more top-end power than previous options.
    • Advanced Compressor Cover: Utilizes a 0.70 AR compressor cover with a redesigned map groove, anti-surge ring, and volute shape, incorporating modern turbo technology for enhanced efficiency.
    • Unmatched Durability: Boasts a redesigned bearing housing and backing plate to accommodate 200% LARGER thrust bearings and upgraded wider and taller journal bearings. An upgraded steel thrust insert replaces the aluminum backing plate, ensuring consistent turbocharger function and eliminating bearing fatigue.
    • Reinforced Structure: The bearing housing offers increased stability, and the backing plate is stronger and cast into the bearing housing for improved rigidity, reducing deflection and distortion under extreme heat and pressure.
    • Effortless Installation: A 100% Drop-In Turbo means no modifications are required for installation, and it comes complete with all necessary gaskets and O-rings, plus a newly upgraded 4" intake boot for better fitment.
    • Proven Performance: Dyno-proven power gains ensure you feel the difference immediately.
    • Enhanced Control: Features a redesigned Round-Top Wastegate Actuator for increased boost control and a High Flow Non-EBPV outlet flange.

    The KC300x G3 Stage 3 Turbo is specifically recommended for vehicles running 238/80 to 250/100 injectors, offering optimal performance within this range. While it will function well with smaller injector sizes, we suggest our S2 turbo for those applications to maximize efficiency. Experience the pinnacle of performance engineering and invest in a turbo that's built to last and designed to dominate.
