BD Diesel Iron Horn 5.9L Turbo Kit S369SXE/80 0.91AR Dodge 03-07

When you're looking to replace a worn-out turbo or simply want to get more out of your 5.9L Cummins engine, the BD Diesel Iron Horn Turbo Kit is a solid choice. This kit is designed as a direct replacement for your factory turbo and exhaust manifold, making installation straightforward without needing extra piping. You get a BorgWarner S300 SX-E turbocharger with a T4 flange, paired with a two-piece pulse exhaust manifold that helps reduce exhaust gas temperatures (EGTs) and drive pressures. This setup is built to increase airflow, which translates to more power, better throttle response, and improved reliability for your truck.

The heart of this kit is the BorgWarner SX-E cartridge, featuring a 69mm compressor wheel and an 80mm turbine wheel with a 0.91 A/R ratio. This combination is capable of flowing 98 lbs/min, making it suitable for trucks aiming for around 700 horsepower, depending on your specific truck configuration and other modifications. The two-piece pulse manifold is designed to improve exhaust gas scavenging, contributing to lower EGTs and more efficient operation. Everything you need for the installation, including the turbo, manifold, gaskets, and necessary hardware, is included in the box, simplifying the upgrade process.

This kit is a popular option for owners of the 3rd generation Dodge Ram 2500 and 3500 trucks from 2003 to 2007. It offers a significant performance improvement over the stock turbocharger while maintaining good drivability. Remember that this kit is not CARB approved and cannot be shipped to California.
