S300 Single Turbos
BEST TURBO UPGRADE for 5.9 DODGE CUMMINS TURBO & 6.7 DODGE CUMMINS TURBO
Efficient spool, solid towing performance, and balanced airflow for everyday use and mild performance builds.
Diesel Power Source S300 turbos are engineered for balanced performance: quick spool, strong midrange power, and lower exhaust temperatures. Designed as a bolt-on upgrade for 5.9 and 6.7 Cummins engines, the S300 improves throttle response and durability. Ideal for trucks used for towing, daily driving, or light performance upgrades.
Why upgrade your diesel turbocharger
- More power and torque - Replace a restrictive factory turbo with a high-flow S300 or S400 unit.
- Lower EGTs - Improved airflow supports better air-fuel ratios under load.
- Faster spool-up - Reduced lag with stronger, earlier boost response.
- Better towing performance - Maintain speed and control on long grades and in headwinds.
- Built to last - Robust wheels, bearings, and housings outperform many OEM units.
How to choose the right S300 for your Cummins
- Daily/towing focus - Smaller compressor options (for example S362 or S364) with tighter turbine A/R favor quick spool and drivability.
- Balanced street performance - Mid-size options (for example S366) deliver strong midrange with manageable lag.
- More headroom - Larger compressors (for example S369) and freer turbine housings add airflow for future fueling, with a modest trade-off in response.
- Housing and flange - Match T3 or T4 flange, wastegate style, and downpipe connection to your manifold and exhaust.
Fitment
Compatible with 5.9L Cummins (1998.5–2007) and 6.7L Cummins (2007.5–2024), depending on turbine housing and mounting hardware. See each product page for flange style, inlet/outlet geometry, and year-specific notes.
Recommended supporting parts
- High-flow intake and fresh air filter
- Quality exhaust manifold matched to the turbo flange
- Boost and EGT gauges for monitoring under load
- Appropriate tuning when fueling or injector changes are added
When to replace your single turbocharger
Simple signs to watch for
- Less power - Noticeable drop in acceleration or towing pull.
- More smoke - Thick, dark exhaust can indicate turbo damage.
- Strange noises - Whining or grinding near the turbo, especially under throttle.
- Oil use - Falling oil level without external leaks may mean the turbo is passing oil.
- Check engine light - Fault codes related to boost control or airflow may point to turbo issues.

Frequently asked questions
Will an S300 work well for towing
Yes. Choose a smaller to mid-size S300 with an appropriate turbine housing for quick spool and steady EGT control on grades.
Do I need tuning with an S300
Many trucks benefit from calibration updates to optimize fueling and shift strategy. If injectors or pumps are upgraded, tuning is recommended.
What else should I upgrade
A quality manifold, intact charge-air plumbing, and good filtration help reliability. Add EGT and boost gauges for safe towing and performance use.
