BD Diesel Iron Horn 5.9L Turbo Kit S364SXE/80 1.00AR Dodge 03-07

If you're looking to replace a worn-out factory turbo or upgrade your 5.9L Cummins engine for better performance, 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 for a cleaner and more straightforward installation. It uses a well-known BorgWarner SX-E cartridge, which is a popular upgrade for its ability to handle more air and reduce exhaust gas temperatures (EGTs) and drive pressures. This helps keep your engine running cooler and more reliably, especially when you're asking more of it.

The kit includes a two-piece BD high-flow pulse exhaust manifold designed for a T4 flange, along with the necessary gaskets and fittings. This setup is built to increase airflow, which translates directly into more power, improved throttle response, and overall increased reliability for your engine. With a flow rate of 82 lbs/min and a 1.00 A/R ratio on the turbine housing, this turbocharger is capable of supporting around 600 horsepower, depending on your truck's specific configuration and other modifications. It’s a well-built kit that balances performance gains with drivability.

When installing this kit, you'll want to ensure you have the correct tools and refer to the manufacturer's instructions for the best results. Because this is a significant upgrade, it's always a good idea to monitor your engine's parameters, especially EGTs and boost pressure, to get the most out of the new turbo and keep your Cummins running strong for years to come.
