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 E99 KC300x Stage 2.
**We Highly Recommend adding these products for best results:**
- Upgrading your Up-Pipes
- Upgrading EBPV Pedestal
- 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.

**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**

Super fast delivery and a very good quality product will be doing business again and will refer KC turbo's to people in the future
I bought this turbo about a year ago and it’s absolutely the best one for the money. Gave the truck a substantial amount of boost and power. I would recommend anyone thats looking for an upgraded turbo with amazing customer support then go with KC
