Stage 2 power with dual ball bearing response.
The KC Turbos Jetfire S2R Gen 2 is a dual ball bearing Stage 2 VGT turbo for the Ford 6.0L Powerstroke. KC spent years redeveloping and testing the Gen 2 design, and it's a 100% drop-in upgrade built to spool fast and make serious power. It runs well on stock injectors and is capable of 600–650 hp with larger injectors and supporting mods. It also keeps great street manners, so your truck feels lighter and more fun to drive.
Gen 2 dual ball bearing center section.
The upgraded Gen 2 dual ball bearing center section provides faster spool response and reduced bearing wear compared to journal bearing designs. It's the same compressor and turbine wheel technology as KC's other Gen 2 turbos, with bigger, stronger dual ball bearings.
Big airflow, quick spool.
KC's redesigned, lighter and stronger 64x88mm single-plane point-milled billet compressor wheel extends to 94mm at the tips. It's housed in an upgraded .70 A/R race compressor cover with KC's signature drilled-hole surge ring for maximum airflow. On the exhaust side, a redesigned 73x66 quick-spool 10-blade turbine wheel and new high-flowing vanes keep response sharp.

- 100% drop-in, no modifications required
- All mounting hardware included
- Brand new, no core required
- Fits 2003 Ford 6.0L Powerstroke
What Problem Does This Solve?
- Bigger turbos usually mean more lag. Many Stage 2 turbos feel sluggish until RPM builds. The S2R's dual ball bearing center section and quick-spool turbine are designed to spool faster, so you get more airflow without losing low-end response.
- Performance injectors outgrow the stock turbo. Once you add larger injectors, a stock or Stage 1 turbo can't supply enough air. The S2R supports injectors up to 190cc/30% and 600–650 hp.
- Complicated turbo upgrades. Many high-horsepower setups require extra parts or fabrication. The S2R is a 100% drop-in VGT that installs in the factory location with the included mounting hardware.
Is This Turbo Right for You?
The S2R is a great fit for 6.0L owners running or planning performance injectors up to 190cc/30% who want strong power with quick spool and good street manners. If you're building for 650–700 hp with injectors up to 205cc/75%, step up to the KC Jetfire S3R Gen 2. If you're running stock injectors and tow heavy, the KC Jetfire Stage 1 is a more budget-friendly choice.
