The Chevrolet Silverado 3500 HD Turbo Install Kit by Wehrli, specifically designed for the S400 series in Bengal Red, is ideal for 2001-2004 Silverado models. This kit provides everything necessary to transition from the original IHI turbo to a more robust Borg Warner S400 setup, enhancing your 6.6L LB7 Duramax diesel engine’s performance.
Enhance your truck’s potential with this meticulously engineered turbo install kit. It features a larger, 5-inch aluminum intake system, a high-performance dry filter complete with a pre-filter cover, and mandrel-bent 14 gauge aluminum tubes designed to maximize airflow. The inclusion of an upgraded billet y-bridge kit replaces the restrictive stock upper intake, optimizing both horsepower and efficiency. Stainless steel braided Parker oil lines ensure high-quality oil feed routing directly from the engine block, while the high-temp ceramic coated turbo downpipe allows simple connection to your existing exhaust without the need for modifications.
