Wehrli S300 Single Turbo Install Kit for 2001-2004 Duramax LB7 Gloss Black Gloss Black 100478-GB

This single fixed vane turbocharger install kit contains what you need to swap from your stock IHI style turbo to a larger frame Borg Warner S300 style setup on a 6.6L LB7 Duramax diesel engine. It upgrades the existing air cleaner setup to a 4" fabricated aluminum intake with a heavy-duty sheet metal air box and a high-performance dry filter with a pre-filter cover. Intercooler hot and cold side charge pipe plumbing are also updated to high flow 3" diameter mandrel bent 14 gauge aluminum tubes. It includes an upgraded high flow 3" fabricated billet y-bridge kit which replaces the restrictive stock upper intake manifold to finish off the airflow path into the engine and allow for maximum horsepower and efficiency gains. Supplied Oil Lines are high-quality stainless steel braided Parker Lines with the oil feed line routing from the main oil galley on the side of the engine block. A variety of popular turbo size options (sold separately) mount to a T4 fabricated steel pedestal with spacer which is compatible with 2" high flow stainless steel up pipes. The included high-temp ceramic coated turbo downpipe connects to your existing exhaust front pipe V-Band clamp, simplifying installation and requiring no cutting or modification to your exhaust system. Includes a Driver Side Transmission Dipstick Tube, making installing the downpipe easier.
