Industrial Injection 03-07 5.9 Cummins S300 SX-E Single Turbo Kit 64/74 With 1.0 A/R

This Industrial Injection S300 SX-E turbo kit features a 64mm compressor wheel and a 74mm turbine wheel, paired with a 1.0 A/R exhaust housing. This specific combination is chosen to offer a significant improvement in airflow over the stock turbo, helping your 5.9 Cummins engine breathe easier and make more power. The SX-E series from BorgWarner, which this kit utilizes, is known for its robust construction and advanced aerodynamics, designed to handle the demands of increased boost and higher exhaust gas temperatures.

When you're looking to upgrade the forced induction system on your 2003-2007 5.9 Cummins, a single turbo kit like this one from Industrial Injection is a popular choice. It's designed to replace your factory turbocharger with a unit that can support more airflow, leading to noticeable gains in horsepower and torque. The 1.0 A/R turbine housing is a larger option that helps reduce exhaust backpressure, especially at higher RPMs, allowing the turbo to spool more efficiently and sustain boost levels longer. This can translate into a more responsive engine and improved towing or performance driving characteristics.

Installing a turbo kit like this often involves more than just bolting on the turbo itself. While this kit is designed as a comprehensive solution, it's important to ensure your fuel system and exhaust can keep up with the increased airflow. Industrial Injection has put together this package to simplify the upgrade process for your 5.9 Cummins, providing a well-matched turbocharger setup. Please note that this kit is not CARB approved and cannot be shipped to California.
