Wehrli 01-04 Chevrolet 6.6L LB7 Duramax S400 Twin Turbo Kit (No Turbo) - Gloss Black

The Wehrli Custom Fabrication S400/Stock Twin (Compound) Turbo Kit is designed for 2001-2004 LB7 Duramax engines, significantly enhancing horsepower, fuel economy, and EGT control with stock-like spool characteristics. This kit supports up to 1000 RWHP with additional modifications. It includes a 5" intake with a dry air filter and Outerwears Pre-Filter, along with various piping components for both cold and hot sides of the turbo system. Hot side pipes are finished with a high-temperature black ceramic coating. The kit also features an atmosphere turbo pedestal, stainless steel oil lines, a coolant overflow tank, and all necessary boots, clamps, and fittings. Please note, this is a "no turbo" kit, meaning the S400 turbocharger itself is not included, and it requires the removal/relocation of the passenger side battery.
