Industrial Injection 03-07 5.9 Cummins S300 SX-E Single Turbo Kit 66/74 w/ 1.0 A/R

This Industrial Injection turbo kit features a 66mm compressor wheel and a 74mm turbine wheel, paired with a 1.0 A/R exhaust housing. This specific sizing is chosen to offer a noticeable improvement in airflow and boost pressure for your 5.9 Cummins engine, especially when you're looking to upgrade beyond the stock turbocharger. The S300 SX-E series turbocharger is known for its robust construction and ability to handle increased demands, making it a solid choice for those seeking more power and responsiveness from their diesel truck.

The kit is designed to integrate with your 5.9 Cummins engine, providing the necessary components for a comprehensive turbo upgrade. Industrial Injection has selected these components to work together, aiming for a balance between improved performance and drivability. The larger wheels and housing allow the engine to breathe more freely, which can lead to better exhaust gas scavenging and increased power output, particularly in the mid to upper RPM range. This upgrade is often pursued by owners who tow heavy loads or want a more aggressive feel from their truck.

When installing this kit, it's important to consider supporting modifications that can help your engine take full advantage of the increased airflow. This might include adjustments to fuel delivery and exhaust systems. Always refer to the manufacturer's installation instructions for specific details and recommended procedures to ensure proper fitment and optimal performance. Please note that this kit is not CARB approved and cannot be shipped to California.
