BD Diesel 1045176 Iron Horn Turbo Kit Cummins - S366SXE/80 5.9L 0.91AR

The BD Diesel Iron Horn turbocharger kit provides a complete drop-in turbo upgrade solution for 2003-2007 Dodge Ram 2500/3500 trucks with the 5.9L Cummins engine. This engineered kit replaces both your factory turbocharger and exhaust manifold with premium components designed for increased performance and reliability.

Key Features:

• BorgWarner S366SXE/80 turbocharger with SX-E cartridge and T4 flange
• Two-piece pulse exhaust manifold optimized for high flow and reduced backpressure
• Compressor wheel: 66mm inducer, flows up to 98 lb/min
• Turbine wheel: 80mm for responsive spool and peak performance
• A/R ratio: 0.91 for balanced performance and drivability
• Supports approximately 500-700 horsepower depending on configuration
• Reduces exhaust gas temperatures and drive pressures compared to stock
• No additional piping required—direct bolt-in installation
• Includes all necessary gaskets for complete installation

Installation and Compatibility:

Installation typically requires 6 hours. Early 2003-2004 model year trucks (305HP HY35 turbo) will require a 2004.5-2007 style aftermarket downpipe and OEM V-band clamp. Aftermarket air intake systems may require minor modifications. This kit is not compatible with turbo-mount exhaust brakes; use a remote-mount exhaust brake instead.

Warranty:

Backed by BD Diesel's 12-month/12,000-mile limited parts warranty. This product meets EPA reasonable basis requirements and is legal for federal use (EMS:2). Not legal for sale or use on California-registered vehicles.
