Description

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. Not recommended for tow rigs.

Don't see what you're looking for here? Check out our S400/S300 or S400/S400 kits for ultra high-performance applications, or give our specialists a call at 630-277-8239 for assistance custom building a setup that will work best for your needs.

***This kit is designed to be used with the OEM exhaust manifold. If you would like to use an aftermarket OEM replacement style manifold like a Steed Speed 3rd Gen T3, you MUST send it in for the kit to be custom-built, and your lead time does not start until the manifold is in our possession.***

***Retains passenger-side factory battery location***
