Smeding Diesel S300 Direct Bolt In Turbo 2011-16 LML Duramax

Smeding Diesel LML Duramax S300 Direct Bolt-In Turbocharger

This turbocharger features our S300 frame NON-VGT design and is designed to bolt directly in using all factory components.

This turbo is truly unique—no other manufacturer offers a true non-VGT direct bolt-on turbo for the LML Duramax. It is compatible with the stock intake, stock downpipe, and stock intercooler pipe, as well as any aftermarket intake, downpipe, or intercooler pipe that fits the factory turbo.

These turbos are capable of producing up to 850 rear wheel horsepower (rwhp) reliably! The S300 turbos will outflow their VGT competitors and operate with lower drive pressure than any VGT available on the market. This results in reduced cylinder pressure, which means less strain on your engine's internals and head gaskets. Consequently, your engine can generate more power healthily with this setup compared to competing VGT systems.

These turbos are currently available with 73mm turbine sizes.
