2003-2007 5.9L Cummins S400/Stock Compound Turbo Kit. 1000 RWHP capable, depending upon turbo and fuel system modifications. Recommended for daily driver work trucks and tow rigs looking for increased horsepower, better fuel mileage, and superior EGT control with stock-like turbo spool characteristics. Recommended Combinations - S475 / Stock Holset Turbo - Up to 750 RWHP with Supporting Modifications - Best Turbo Spool, performs well on stock fuel setups. S480 / Stock Holset Turbo - 800+ RWHP Capable with Supporting Modifications - A better top-end performance that sacrifices a bit of spool on the lower end when compared to an S475/stock setup. S480 / 63 or 64 Upgraded Drop-In Turbo - 900+ RWHP Capable with Supporting Modifications - Improved top end power with moderate spool characteristics S480 / 67 Upgraded Drop-In Turbo - 1000+ RWHP Capable with Supporting Modifications - Best Top End Power, sacrifices low-end power and turbo spool - Manual trans trucks will allow best use of power band for this setup. The S480 / 67 upgraded drop-in setup is not recommended for tow rigs due to spool characteristics. Not sure which kit is right for you? Give us a call to discuss your build.
