Because of the popularity of the old KC KC38r turbo for the 7.3 Powerstroke, we have made 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! We have spent several years on research and development modifying and battle testing our original ball bearings so that we could bring you the best and most reliable ball bearing design KC Turbos has ever produced.

The new KC38r compressor wheel is drastically different, it is a larger 7x7 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 a 6.4mm on the original to 7.5mm for increased strength and longevity. 

This dual ball bearing turbo will surprise you at how much it will wake up your 7.3! We have torture tested it for longevity, proven its capability on the dyno, and at the Race Track. For dedicated tow rigs and daily drivers, the .84 A/R Housing provides a quicker spool and cooler EGT's below 3000 RPMs.

**We Highly Recommend adding these products for best results:**

  1. Upgrading your Up-Pipes
  2. Upgrading EBPV Pedestal 
  3. Running a Hydra Programming Chip

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**

I own a 2000 F350 7.3 I’m a Union pipeline welder the truck is my welding rig! Purchased the Tiger Turbo, installed this and cnc fabrications 4 line system! Both are amazing! The turbo provides much more boost along with a Significant exhaust temperature drop! I’m noticing a little more than 200 degree egt loss! Impressive I must say. Very quiet turbo! Best purchase I’ve made for this truck in a while....

E99 Turbo and Injectors

I asked a lot of questions before ordering, all were answered and never felt like he was getting annoyed with all the questions. I got it all squared away and placed an order for an E99 63/73 KC Turbo and some 180/30 sticks.

All the shipping was very fast and I had all parts within 1 week of ordering, except for the injectors but that was because I chose to send mine in first. The tunes were even delivered the same day I got my truck info to them.

First impressions are summed up with one word WOW. I have buried my psi gauge at 35 psi, looks like it might be time for a bigger gauge. The turbo will start to build boost around 1800 rpm it will be around 5 psi with a load, at cruse about 2-3 psi, at about 2k it really wakes up and if I stay in it will quickly climb all the way to 35 psi. The egt’s have only got up to 1100° and just pretty much stay right there, once the turbo fully spools.

The single shot injectors don’t really sound any loader then the stock split shots. I have not had a chance to pull a normal heavy load with it yet, but I have pulled 6k behind the truck and it felt great. No issues, I liked the way the transmission shifted and how the truck pulled it with ease. I am sure once I put the full load behind the truck it will do every bit as well.

The truck feels great and it is everything I was after with the goals I had for the truck. If they sell the parts I need I will purchase from them again without hesitation.
