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! KC has 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 want a large boost in performance, check out the E99 KC300x Stage 2.

• KC Turbos highly recommends adding these products for the best results:
• Upgrading you up-pipes
• Upgrading The EBPV Pedestal 
• Running Custom Tuning
• This turbo requires you to do a CCV mod to the truck since the boot is not long enough to work with the stock plastic CCV tube. If you don't know or don't fully understand what a CCV mod entails, please do a quick "7.3 CCV mod" Google search or feel free to give us a call with any questions!
• Most turbochargers will typically come sand-cast unless specifically requested, however, a polished cover may be added for an additional fee.
• EXHAUST BRAKES: Do exhaust brakes work with KC turbos? KC Turbos has 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 aid 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.
•  KC turbos are designed to fit directly in 7.3 equipped pick-up trucks. Although KC turbos can drop into 7.3 equipped Vans, you will need to modify the turbo intake boot and down-pipe for proper fitment.
• 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.
