Industrial Injection 03-07 5.9 Cummins S300 SX-E Single Turbo Kit 62/74 w/ 1.0 A/R

If you're looking to significantly increase the power and performance of your 2003-2007 5.9L Cummins, a single turbo upgrade is a popular way to go. This Industrial Injection S300 SX-E turbo kit is built around a robust BorgWarner S300 SX-E turbocharger, specifically the 62/74 model with a 1.0 A/R turbine housing. This setup is designed to offer a substantial improvement in airflow and boost pressure compared to the stock turbo, making it a solid choice for those seeking more towing power or higher performance on the street.

The S300 SX-E turbocharger is well-known for its durability and ability to handle increased boost levels, making it a reliable option for modified Cummins engines. The 62mm compressor wheel is paired with a 74mm turbine wheel, providing a good balance for improved spool-up while still supporting higher horsepower goals. The included 1.0 A/R turbine housing helps to manage exhaust gas flow efficiently, contributing to better performance across a wider RPM range. This kit includes the necessary components to get the turbo installed, though it's always a good idea to check the included hardware list to ensure you have everything for your specific setup.

This turbo kit is a significant upgrade for your 5.9 Cummins. It's important to note that this kit is not CARB approved and cannot be shipped to California. For optimal performance and longevity, consider consulting with a professional installer or referring to the manufacturer's installation guide for specific recommendations regarding exhaust, fueling, and tuning adjustments that often accompany a turbocharger upgrade of this caliber.
