Industrial Injection 03-07 5.9 Cummins S300 SX-E Single Turbo Kit 63/74 w/ .91 A/R

If you're looking to significantly increase the power and responsiveness of your 2003-2007 5.9L Cummins, this Industrial Injection S300 SX-E Single Turbo Kit is a solid choice. This kit is designed to replace your stock turbocharger with a more capable unit, allowing your engine to breathe easier and produce more power, especially at higher RPMs. It's a popular upgrade for owners who tow heavy loads or want a noticeable performance boost for their truck.

The heart of this kit is the BorgWarner S300 SX-E turbocharger, known for its robust construction and improved airflow compared to older designs. The 63mm compressor wheel and 74mm turbine wheel combination, paired with a .91 A/R turbine housing, offers a good balance between quick spool-up and high-end power. This means you'll feel a stronger pull sooner when you accelerate, and the engine will continue to make power further into the rev range. Industrial Injection has put together a complete kit, meaning it includes the necessary components to get this turbo installed on your 5.9 Cummins, making the upgrade process more straightforward.

When installing a turbo kit like this, it's important to consider supporting modifications. While this kit is designed to be a comprehensive solution, ensuring your fuel system and exhaust can handle the increased airflow and power is key to unlocking its full potential and ensuring long-term reliability. This kit is not CARB approved and cannot be shipped to California.
