7.3L Power Stroke Turbo Upgrade

7.3L Power Stroke

Because KC Turbos‘ tried-and-true KC38r turbo for the 7.3L Power Stroke was so popular among modified truck owners, KC Turbos decided to make a smaller version of the turbo for those running average-size injectors. That’s right, the original KC38r “Tiger Turbo” is back and better than ever. KC Turbos spent several years in research and development, modifying and battle testing the original ball bearings so that they be sure to deliver the best and most reliable ball bearing design KC Turbos has ever produced.

The new KC38r compressor wheel is drastically different, as it is a larger 7×7 KC300x Gen 2 compressor wheel. This newly redesigned compressor wheel is based on the 366SX-E compressor wheel and shares a similar blade profile except it is reverse rotation.

The turbine wheel also takes design notes from the 366SX-E but its larger diameter offers more flow and increased strength through the introduction of thicker blades, a thicker hub, and a thicker rear webbing making it much less prone to fatigue and wheel burst. The redesigned dual ball bearing center housing has been modified to accept the turbine’s increased shaft thickness from 6.4mm to 7.5mm for increased strength and longevity.

This dual-ball-bearing turbo will surprise you with how much it will wake up your 7.3L Power Stroke KC Turbos has torture tested it for longevity, and proven its capability on the dyno and at the race track. This is for dedicated tow rigs and daily drivers, the .84 A/R housing provides a quicker spool and cooler EGTs below 3,000 rpm.

The Stage 2 KC38R will support engines with up to  205cc/30-percent-over injectors while the Stage 3 will work perfectly with 238cc/80-percent-over injectors. Give KC Turbos a call today and find out which turbo is best for your rig.
