A Diesel Power Source® S300 turbo is a single-turbo upgrade built on the S300 platform in five configurations: the S362, the S363 with two turbine options, the S366, and the S369. It covers stock power through 750+ RWHP on the 5.9L Cummins and bolts to the T3 flange at the factory manifold location. Every DPS S300 has a forged milled compressor wheel (FMW), a 360° thrust bearing, a divided scroll turbine housing, a high-flow dual valve wastegate, and a larger diameter turbine shaft than the factory Dodge Cummins turbo. On the 6.7L, the S300 installs through the 3rd Gen Swap Kit or as a T4i Turbonator® VGT.

Which S300 Size Is Right for You?
Towing and Daily Driving
The S362/68/.70 or S363/68/.70. The divided scroll .70 housing makes boost early, which is what you want when pulling a grade or merging with a trailer. The S362 flows about 76 lb/min, more than the largest factory Cummins pickup turbo at about 67 lb/min, and typically runs 100°F or more cooler than the factory turbo.
Street Performance
The S363/73/.80 or S366/73/.80. The 73mm turbine and .80 housing add exhaust flow for higher fueling. Each step up in compressor size spools a little later, so match the turbo to the fuel the truck actually has.
High HP and Competition
The S369/73/.80 is the largest S300 compressor. It makes strong power but can surge when towing. For a high-horsepower truck that tows, DPS typically recommends the S366 or a compound kit instead.
S300 on the 6.7 Cummins
The 3rd Gen Swap Kit replaces the factory VGT with an S300 and a 2-piece manifold. The S300 Turbonator® VGT bolts to the factory T4i manifold in S363, S366, and S369 sizes and keeps the factory exhaust brake.
Available Upgrades on Every S300
Ball Bearing CHRA
Dual ceramic ball bearings spool approximately 200 RPM sooner than a journal bearing at the same horsepower. Synthetic oil is required, and the supplied oil restrictor fitting must be used. Learn more about ball bearing turbos.
Turbonator® VGT Housing
Replaces the fixed turbine housing with a variable geometry housing that adjusts A/R from approximately 0.45 to 1.1. It spools 200-300 RPM sooner than a fixed housing with the same compressor wheel, and the electronic version adds exhaust brake capability. View Turbonator® VGT options.
Start Single, Go Compound
An S300 single can later become the high-pressure turbo in a compound system by adding an S400 with a DPS Add-A-Turbo kit, or you can go straight to a full compound turbo kit. Tell DPS when you order if compounds are in the plan.

Good to Know
- DPS S300 turbos are oil cooled. No coolant lines are required.
- The exhaust manifold, gaskets, and oil lines are sold separately from the turbo.
- On the 6.7L, the 3rd Gen Swap Kit replaces the factory turbo and is for trucks that have already been deleted. Diesel Power Source® does not sell emissions delete components.
- Tuning is the owner's responsibility. DPS does not sell tuners or tuning.
- Warranty under the Diesel Power Source® PMA: S300 turbos and ball bearing turbos are covered for 1 year / 15,000 miles, whichever comes first. Registration within 14 days of purchase is required.
