BD Diesel Iron Horn 5.9L Turbo Kit S366SXE/80 1.00AR Dodge 03-07

If you're looking to replace a worn-out factory turbo or simply want to unlock more power from your 5.9L Cummins engine, the BD Diesel Iron Horn turbo kit is a solid choice for your 2003-2007 Dodge Ram 2500 or 3500. This kit is designed as a direct replacement, meaning no extra piping is needed, making the installation cleaner and more straightforward. It's built around a BorgWarner SX-E cartridge, known for its performance and reliability, and features a two-piece pulse exhaust manifold that helps reduce exhaust gas temperatures (EGTs) and drive pressures.

The Iron Horn kit uses a 66mm compressor wheel and an 80mm turbine wheel with a 1.00 A/R ratio, capable of supporting around 650 horsepower depending on your truck's specific configuration. This setup is engineered to increase airflow, which translates to better throttle response, more power, and improved overall reliability for your engine. BD Diesel has configured this kit to offer a good balance between performance gains and maintaining drivability, so you get a noticeable improvement without making the truck difficult to manage.

Included in the kit is the turbocharger itself, a high-flow T4 manifold, and all the necessary gaskets and hardware for installation. While this kit offers a significant upgrade, please note that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for the most accurate guidance.
