2011-2016 Duramax S300 Direct Bolt-In Turbo (SMED-0586)

Fits

This turbo is one of a kind! Nobody else on the market makes a true non-vgt, direct bolt-on Turbo for the LML Duramax. This turbo will utilize the stock intake, stock downpipe, and stock intercooler pipe as well as ANY aftermarket intake, downpipe or intercooler pipe that fits the factory turbo.

This Turbo is capable of up to 850 RWHP reliably! These S300 turbos will outflow the VGT competition and operate with LOWER drive pressure than any VGT on the market! This boils down to lower cylinder pressure which means less strain on your internals and head gaskets meaning your engine can make more power healthily on this setup than on a competing VGT setup!

Part Number: SMED-0586

• Direct bolt-in
• Utilizes the factory components 
• true non-VGT
• Produces up to 850 RWHP

When you go from cast to billet, you get a lighter wheel. A lighter wheel means there is less rotational mass on the shaft, therefore you have a faster spool up. Peak horsepower will stay the same but you will gain a little bit better driveability.

The SXE-R (competition or race series wheel) is similar in the fact that it is even lighter than the standard billet, but it also has other geometrical differences. The hub itself is smaller, so although you have the same outside to outside diameter, you have a wider blade which means you have more surface area on the blade to move more air. The blades are also arched to provide more surface area as well. The nut on the wheel is also integrated into the wheel, as opposed to using a steel nut on the rest of the wheels. All of these differences provide a faster spooling wheel that pushes more air.

• Currently, these are all available with 73mm Turbines.
