The KC38r is Back – Stronger and More Reliable Than Ever!

The original KC38r turbo has returned, now better than ever. After years of research, development, and battle testing, KC Turbos has engineered its most durable and high-performing ball bearing design to date.

Upgraded Design for Maximum Performance

🟣 Larger 7x7 KC300x Gen 2 Compressor Wheel – Redesigned for greater efficiency and power, inspired by the 366SX-E with a reverse rotation blade profile.

🟣 Reinforced Turbine Wheel – Featuring a larger diameter, thicker blades, a stronger hub, and enhanced rear webbing, significantly reducing fatigue and wheel failure while improving airflow and durability.

🟣 Enhanced Dual Ball Bearing Center Housing – Modified to accommodate an increased turbine shaft thickness from 6.4mm to 7.5mm, providing greater strength and longevity.

Proven Power & Performance

This dual ball bearing turbo is designed to transform the 7.3 Powerstroke, delivering exceptional responsiveness and power gains. Rigorously tested on dynos, race tracks, and real-world conditions, it is built to withstand extreme performance demands.

✅ For Daily Driving & Towing: The .84 A/R Housing delivers quicker spool and cooler EGTs below 3000 RPMs.

The KC38r is the ultimate drop-in turbo upgrade, offering unmatched durability, efficiency, and power for 7.3 Powerstroke owners looking to take their performance to the next level.

EXHAUST BRAKES:  We get asked a lot about exhaust brakes and if they work with our turbos, these will retain the OEM feature if the vehicles calibration allows and is setup for it. We have found that some brands have clearance issues and might cause the brake to hinder performance, rub the turbine wheel, or cause other issues.  These brakes typically use some sort of flapper to close which causes extreme exhaust back pressure to aide in braking.  This can be hard on a turbo and motor and is not recommended. 

**Our turbos are designed to fit directly in 7.3 equipped pick-up trucks. Although our turbos can drop into 7.3 equipped Vans, you will need to modify the turbo intake boot and down-pipe for proper fitment**
