Description

2001-2004 LB7 Duramax 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 IHI Turbo - Up to 750 RWHP with Supporting Modifications - Best Turbo Spool, performs well on stock fuel setups. WCFab 750 Built Allison transmission recommended.

S480 / Stock IHI Turbo - 800+ RWHP Capable with Supporting Modifications - Better top end performance that sacrifices a bit of spool on the low end compared to an S475/stock setup. WCFab 750+ Built Allison transmission recommended.

S480 / Stealth 64 Drop In Turbo - 900+ RWHP Capable with Supporting Modifications - Improved top end power with moderate spool characteristics. WCFab 750+ Built Allison transmission recommended.
