Industrial Injection 03-07 5.9 Cummins S300 SX-E Single Turbo Kit 62/68 w/ .91 A/R

This Industrial Injection turbo kit uses a 62mm compressor wheel and a 68mm turbine wheel, paired with a .91 A/R exhaust housing. This specific combination is chosen to offer a noticeable increase in airflow and exhaust gas velocity, which translates directly into more power and torque for your 5.9 Cummins engine. It’s designed to be a significant upgrade over the stock turbocharger, helping your engine breathe better and perform more efficiently, especially under load or when towing.

The S300 SX-E series turbocharger is known for its robust construction and improved efficiency compared to older designs. The larger compressor wheel helps move more air into the engine, while the precisely matched turbine wheel and housing manage exhaust gases effectively. This setup aims to provide a broader powerband, meaning you’ll feel the pull sooner and it will continue further into the RPM range. This kit is intended for owners looking to extract more performance from their 5.9 Cummins, whether for daily driving, heavy hauling, or competition use. It’s a well-built component designed to handle the demands of a performance diesel engine.

When installing this turbo kit, consider that it's a substantial upgrade and may benefit from other supporting modifications to maximize its potential and ensure long-term reliability. This includes ensuring your exhaust system can handle the increased flow and that your fueling system can keep up with the engine's increased air intake. Always refer to the manufacturer's installation instructions for specific details and recommended procedures to ensure a proper and safe installation.
