Due to the immense popularity of KC Turbos' original KC38r turbo among enthusiasts of modified trucks, KC Turbos has introduced a smaller variant for those with average-size injectors. The beloved KC38r “Tiger Turbo” has made a triumphant return, now better than ever. After years of dedicated research and development, KC Turbos has refined and rigorously tested the ball bearings to ensure they deliver the most reliable and robust ball bearing design in the company's history.
One of the standout features of the new KC38r is its dramatically redesigned compressor wheel. This larger 7×7 KC300x Gen 2 compressor wheel, inspired by the 366SX-E, sports a similar blade profile but with reverse rotation. Additionally, the turbine wheel, while also taking cues from the 366SX-E, boasts a larger diameter for enhanced flow and increased durability. This is achieved through the inclusion of thicker blades, a more robust hub, and reinforced rear webbing, all of which significantly reduce the risk of fatigue and wheel burst.
The upgraded dual ball bearing center housing has been adapted to accommodate the turbine's increased shaft thickness, now 7.5mm up from 6.4mm, offering greater strength and longevity. This turbocharger will undoubtedly invigorate your 7.3L Power Stroke, having been torture tested for durability and performance, both on the dyno and at the race track. Designed for dedicated tow rigs and daily drivers alike, the .84 A/R housing ensures a quicker spool and cooler EGTs under 3,000 rpm.
For those with specific engine setups, the Stage 2 KC38R is suitable for engines with up to 205cc/30-percent-over injectors, while the Stage 3 is ideal for engines with 238cc/80-percent-over injectors. Contact KC Turbos today to determine the perfect turbo for your truck.
