2003-2007 5.9L Cummins S400/Stock Compound Turbo Kit. 1000 RWHP capable, depending upon turbo and fuel system modifications.

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.
