Description:

Improve your 7.3 Powerstroke engine's performance with the KC300x Stage 2 63/73 Gen 2 Turbo. This turbo features a 4" ported housing with drilled anti-surge for better flow, a 63mm 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.

**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.**

**These turbos come sand cast unless specifically requested. 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**

Blown Away

Now being from Canada... I unfortunately could not buy right off the site. Even still the boys at KC helped. Exchanged a few emails, talked about plans and turbo sizing. They answered everything, including giving me piece of mind that the stage 2 would work with stock injectors. I was skeptical.

Installed last night... had a few boost leaks (up pipes and
charge air cooler clamp). Fixed those and boy oh boy what a difference.

On the highway at 60miles an hour EGT is only 100-150 degrees hotter than stock turbo (which is to be expected on stock injectors and I was told about), but once you get a bit higher in the RPM and the turbo lights EGTS level out and even on my hot tune at 35psi I run out of gear before the EGT goes above 1050.

I still need to do injectors as mine are higher mileage but even on stock sticks I am blown away with the performance of this thing.

The new OE style turbo inlet boot is perfect as well, gives the turbo a stock appearance.

woke the beast up

Picked up a KC300x Stage 2 Turbo (63/73) for my 2000 7.3 Excursion and wow I am very impressed! Definitely woke the beast up and makes it fun to drive.

must have for anybody looking

My old 7.3 turbo with 328k was worn out and ready for a replacement after injector upgrade. The guys over at kc turbo hooked me up with a stage 2 63/73 that looking back is a must have for anybody looking to update their old workhorse. The turbo is good quality and comes with the required seals and gasket to install, plus stickers!
