Discover Kc Turbos Kc300x Stage 3 Turbo 66/73 For 1994-1998 Ford 7.3l Powerstroke Diesel Family Size [sr7ACMRf]

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.

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.

  • 100% drop in turbo (no modifications required)
  • 66mm 7x7 SXE style compressor wheel with extended tip technology
