This combination is a popular choice for 5.9 Cummins owners looking to significantly improve their truck's performance beyond stock.

Industrial Injection has a reputation for building robust components, and this turbo kit is no exception. The S300 SX-E series turbocharger is known for its durability and ability to handle increased boost levels. The specific sizing of the compressor and turbine wheels, along with the larger 1.0 A/R exhaust housing, helps to reduce exhaust backpressure and improve exhaust gas flow. This means the turbo can spool up efficiently and sustain boost pressure, leading to better overall engine performance and potentially improved fuel economy under certain conditions. The kit is designed to be a comprehensive upgrade, aiming to provide a straightforward installation process for those familiar with turbocharger systems.

When installing a turbo kit of this caliber, it's important to consider supporting modifications. While this kit is designed to be a complete single turbo solution, ensuring your fuel system and cooling system are up to the task will help you get the most out of the upgrade and maintain reliability. Always refer to the manufacturer's installation instructions for specific details and recommended procedures to ensure a proper and safe installation.
