Industrial Injection 03-07 5.9 Cummins S300 SX-E Single Turbo Kit 64/68 With .91 A/R

If you're looking to significantly increase the power and performance 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 more freely and generate more horsepower and torque. It's a popular upgrade for owners who tow heavy loads or want a noticeable boost in acceleration and overall performance.

At the heart of this kit is the BorgWarner S300 SX-E turbocharger, featuring a 64mm compressor wheel and a 68mm turbine wheel. This combination offers a good balance between improved airflow for higher power output and a responsive feel, especially when paired with the included .91 A/R exhaust housing. The larger housing helps to reduce exhaust backpressure, allowing the turbo to spool more efficiently and keep exhaust gas temperatures in check during demanding use. Industrial Injection has put together a comprehensive package, including the necessary components to integrate this turbo into your 5.9 Cummins engine. This means you get a well-thought-out system that aims for a straightforward installation process, minimizing the need for custom fabrication.

When installing a turbo kit of this caliber, it's always a good idea to ensure your fuel system and exhaust can support the increased airflow and power. Many owners also opt for supporting modifications like an upgraded exhaust system and potentially an engine tuner to fully realize the potential of this turbocharger. This kit is a significant upgrade for your Cummins, offering a substantial improvement in performance for those who need more power for work or play.
