Description:

 

Improve your 7.3 Powerstroke engine's performance with the KC300x Stage 3 66/73 Gen 2 Turbo. This turbo features a 4" ported housing with drilled anti-surge for better flow, a 66mm 7x7 SXE style compressor wheel with extended tip technology, and a 73mm SXE style turbine wheel. The KC300x is a reliable journal bearing drop in turbo perfect for increasing your 7.3 Powerstroke's performance. 

This 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. The 1.0 A/R Housing is intended to cool your EGTs above 3000 RPMS. For dedicated tow rigs and daily drivers, the .84 A/R Housing will provide a quicker spool and cooler EGT's below 3000 RPMs.

This turbo is not recommended for heavy towing. If you are looking for a turbo that can be used for heavy towing, but still are looking a large boost in performance, check out the OBS KC300x Stage 2.

**Please select your trucks CCV when ordering**

**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.  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.  It will be up to the customer to verify fitment and functionality.**

**Pictured is a polished cover, these turbos come sand cast unless specifically requested. You may get a polished unit depending on stock. You can add a polished cover for an additional $250. Two week lead time on all polished covers**

**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**

Great product… better people!!!!

I started purchasing all the parts needed to build my 7.3 about a year ago give or take, I wasn’t sure on what injectors I wanted there for I wasn’t sure what turbo would be good for me. At first I figured 180/100s and a stage two turbo. So I ordered the stage two turbo then changed my mind and decided to get 235/80s as it was otw to my house lol. Called and let them know I’d be returning the stage 2 to get a stage 3 turbo and pay the difference, was waiting and waiting for it to get to kc’s wearhouse so I finally called one day just to get a update, come to find out they already had the stage 3 turbo on the way to my door… not a hassle or problem what so ever dealing with kc. Best customer support and the turbo showed up shiny and better then it looks on the website… great people great product
