Get more power and performance out of your 2001-2004 GM 6.6 Duramax LB7 by adding an S400 to your factory turbo with the HSP LB7 Add-A-Turbo Kit (No Turbo). While the stock charger is great for quick throttle response and bottom end torque, power falls off under heavy loads and leaves much to be desired when using performance tuning. HSP solved this problem by adding an S400 frame turbo to the factory unit resulting in lower EGT's, increased fuel economy, and a much broader power curve. No cutting or modification is involved for installation, meaning you get to keep your 2nd battery for all its added benefits. Power levels can range from 600-850HP depending on supporting modifications.
- Lower EGT's
- Keeps Both Batteries
- Support Up To 850HP
- Increased Performance
- S400 Compound Installation Kit
Note: Aftermarket S400 turbocharger and aftermarket custom tuning required for installation (not included).
Application Note: Will not work with the factory LB7 style FCA (Fuel Pressure Regulator). Must be upgraded to LLY or LBZ.
