Smeding Diesel S300 Turbo 07.5-18 Dodge/Ram 6.7L Cummins

If you were forced to replace a major component on your truck due to premature failure, would you give that same part another chance, or would you want a more reliable solution? A more reliable, more affordable and guaranteed performance gain, the Smeding Diesel S300 replacement turbo for the 6.7L Cummins is the choice for you. When we emphasize "replacement", we mean it. This direct drop-in replacement doesn't require any additional parts to install, besides custom tuning to recalibrate the ECM for the change in turbo. Remarkably, even the factory exhaust manifold can remain unchanged. Thanks to Smeding's T4 inlet flange, it effortlessly bolts directly onto a stock manifold and to further simplify things, each turbo comes with an oil feed adapter, oil drain extension, and two coolant plugs. By doing this upgrade, the factory exhaust brake will no longer be functioning because of the removal of the VGT turbo. A VGT turbo, or Variable Geometry Turbo, is a type of turbo that is equipped on 2007.5 and newer Cummins-powered Ram trucks. This turbo has adjustable vanes or blades in the turbine housing that can change their angle to control the flow of exhaust gases into the turbine wheel. Although a unique design, this function is commonly failed by the electronics that control it, hence the S300 upgrade.  The term "S300" refers to a series of turbochargers produced by BorgWarner that comes in many different shapes, sizes and specifications and are often used in high-performance or aftermarket applications. These are "fixed vane" units that are much less failure prone and stand as a tried-and-true piece in the performance diesel space.
