In addition to an upgraded turbo, our comprehensive kit comes with everything you need to install an S300 on your ’07.5-’18 6.7L Cummins. This includes a new, two-piece T4 divided exhaust manifold, which outflows the factory unit and provides for quicker spool up. Fresh exhaust manifold gaskets and mounting bolts simplify manifold installation, and the supplied coolant plugs, oil drain extension, and turbo drain gasket make the job as straightforward as possible. And, with our S300 Turbo Kit starting at $1,500 it’s considerably more affordable than any replacement (and even remanufactured) OEM VGT!

Thanks to our upgraded exhaust manifold positioning the S300 in the stock location, all of the factory components surrounding the turbo can be retained. That means your factory air intake, downpipe, and intercooler piping don’t have to be changed out (a welcomed cost savings). We streamline the installation of our kit even further by supplying you with all necessary hardware, hose clamps, gaskets, and fittings required for the job. This is how you truck should have come from the factory.

As with all of our turbo kits, the S300 system for the 6.7L Cummins ranges from a standard cast compressor wheel option for stock fuel trucks to a billet wheel version capable of supporting more than 650 hp. Our 62mm and 66mm cast compressor wheel options feature time-tested, cast-aluminum construction, a proven 7-blade design, and represent the most cost-effective wheel option in our arsenal. Our billet compressor wheels are CNC machined out of a solid block (billet) of aluminum to our exact specifications. These upgraded wheels are lighter, provide quicker spool up, and range in size from 63mm all the way up to 72mm. But make no mistake, even the cast 62mm option is a major upgrade from the factory VGT. For utmost durability, we also offer heavy duty and extreme duty 360-degree thrust bearing assemblies.

The term cast wheel is referencing the material used to produce the compressor wheel. Our cast wheels are made of cast aluminum and they are a 7 blade design, this style wheel has been around for many many years and is very reliable. Cast wheel are the most cost effective wheel option we offer.

Billet wheel means that the compressor wheel is made from a solid block of aluminum that is CNC machined to our exact specification. Billet wheels are much more advanced wheels compared to there cast wheel counterparts because we can use a stronger material, more aggressive blade designs, and make them lighter weight then a cast wheel. Billet wheels will provide faster spool up and make more horse power then a cast wheel will. Most of our billet wheel utilize a 6 blade design!
