It works well on stock injectors and performs even better with larger injector setups up to 190cc. For this reason, it fits both street-driven trucks and performance builds. Unlike journal-bearing turbos, the dual ball bearing design reduces friction. As a result, the S3R delivers smooth power across the RPM range while maintaining strong low-end torque. KC S3R Gen 2 Turbo Tuning Recommendation For best performance and reliability, use quality aftermarket tuning matched to your injector size and turbo setup. KC S3R Gen 2 Turbo Lead Time & Notes Powder-coated or polished covers may require additional lead time Turbo uses the 2004–2007 mounting style Designed as a direct bolt-on for 2003–2007 6.0 Powerstroke trucks KC S3R Gen 2 Turbo Exhaust Brake Compatibility This turbo retains OEM exhaust brake functionality when vehicle calibration supports it. However, some aftermarket exhaust brake systems restrict exhaust flow. Because flapper-style designs create excessive backpressure, we do not recommend using them with this turbo.
