KC Turbos KC300x G3 Stage 1 Turbo Early 99 Ford 7.3L PowerStroke

The KC300x Stage 1 Gen 3 Turbo (63/68) for the 7.3L PowerStroke (E99) is a premium drop-in performance upgrade engineered to bring more responsiveness, airflow, and all-around performance to your truck without requiring modifications to the engine or turbo support systems. This turbo features a 3.5" ported housing with drilled anti-surge for better flow, a completely redesigned Gen 3 7x7 SXE style compressor wheel with extended tip technology and with upgraded aero to aid in quick spool, and a SXE style turbine wheel with a thicker shaft inside of completely redesigned compressor and turbine housings. The Gen 3 KC300x features a .91 AR Turbine housing and a 0.70 AR compressor cover. Originally a 1.0 AR compressor cover, we changed it to a .70 AR cover with redesigned map groove, anti surge ring, volute shape and style with modern turbo technology. The turbine housing was previously available in .84 and 1.0ar; both are inefficient when compared to modern turbos. We took inspiration from the latest turbochargers in the market and applied their turbine housing design , flow path, volute shape, and material density to come up with our own 0.91AR turbine housing. This turbine housing was proven to spool up faster AND make more top end power when compared to either previous option. FEATURES & BENEFITS: 100% drop-in turbo: no modifications required for installation Redesigned Gen 3 7x7 SXE style compressor wheel with upgraded aero Thick Shaft Gen 3 SXE style turbine wheel Redesigned quick spool 0.70AR Ported Compressor Cover Improved MAP Groove, Anti-Surge Ring, and Volute Shape Redesigned 0.91AR Turbine Housing with upgraded volute technology for Quicker Spool & More Top End Power Spools FASTER than the old 0.84AR and flows MORE air than the old 1.0AR due to this radical redesign 200% Larger Thrust and Journal Bearings Thicker turbine shaft to accommodate larger bearings and higher boost and HP levels. Stock shaft sizes can deflect and result in catastrophic failures Redesigned Bearing Housing with integrated cast iron backing plate for improved high speed stability by reducing deflection Added Steel Thrust Insert to Reinforce oil slinger and piston seal Contact Areas & Eliminate Bearing Fatigue High Flow Non-EBPV outlet flange Redesigned Round-Top Wastegate Actuator for increased boost control Comes with all gaskets and o-rings to install Comes with newly upgraded 3.5" intake boot with better fitment over previous designs APPLICATION NOTES: Fits 7.3L PowerStroke trucks equipped with E99 (engine code) 100% drop-in design: retains stock location and connections Polished or sand-cast cover options available for finish preference Early 1999 only 1999 PowerStroke Owners: To determine if your truck is an early or late 1999 model year, locate the tag on the drivers side door. Vehicles built before 12/7/98 are considered early 99 and vehicles built after 12/7/98 are considered late 99. The KC300x Stage 1 Gen 2 turbo is ideal for owners who want a noticeable performance upgrade over stock without the complexity of a full custom turbo system.
