BD Diesel

Stock replacement turbos. Direct replacements for factory VGT turbos, such as the HE351 on 2007.5 to 2012 Ram 6.7L Cummins pickups and the HE300VG on later trucks. These keep factory boost control and emissions equipment, and they're the right choice when a stock turbo fails and the truck is otherwise stock. BD Diesel Turbochargers

Screamer performance turbos. BD's Screamer line keeps a stock appearance and factory mounting but uses larger compressor and turbine wheels. BD typically re-machines OEM-style housings to fit its Ballistic Billet compressor wheels and Low-MOI (low inertia) turbine wheels, and VGT versions ship with a new or calibrated actuator. The goal is quicker spool and lower EGTs than stock at the same tune, with more headroom for tuned trucks.

Screamer retrofit kits for the 6.7L Power Stroke. Stage 1 and Stage 2 Screamer kits for 2011 to 2016 Ford 6.7L Power Stroke trucks.

Iron Horn turbo kits. Fixed-geometry single turbo kits for the 2003 to 2007 5.9L Cummins, built around BorgWarner S300SX-E frame turbos (S361, S363, S364, and S366 variants) with different compressor sizes and turbine A/R options. Iron Horn kits typically include the manifold, oil lines, and hardware for the swap. They suit trucks with upgraded fueling that need more airflow and lower drive pressure than the stock turbo can deliver.

Howler VGT kits. The 2003 to 2007 5.9L Cummins came with a fixed-geometry turbo. BD's Howler kits convert it to a variable geometry turbo controlled by a standalone controller, aiming for quicker spool and more control over boost. The complete install kit includes the controller.

Stock replacement, Screamer, or a full kit?

Choose a stock replacement if your turbo failed, the truck is stock or close to it, and you want factory drivability and emissions compatibility.

Choose a Screamer if you're replacing a turbo on a tuned or lightly modified truck and want better spool, lower EGTs when towing, and room to grow, without changing the factory layout.

Choose an Iron Horn or other full kit if you've upgraded injectors and fueling and need more airflow than a stock-location turbo can supply. These typically require tuning and supporting modifications.

• Match the exact truck. Year, engine, and body style all matter. Pickups and cab and chassis trucks of the same year can use different turbos, and mid-year changes are common on diesel platforms.
• Check the emissions configuration. If your truck needs to stay emissions compliant, choose a part with a CARB EO number for your application.
• Match the turbo to your fueling. Stock-appearing turbos typically work well on stock or mildly tuned trucks. Larger frame kits need injectors, fuel supply, and an intercooler that can keep up.
• Size for how you use the truck. A smaller turbine A/R typically spools faster and suits towing. A larger A/R typically lowers drive pressure and EGT at high power but spools later.
• Budget for calibration. Even drop-in turbos benefit from a health check. Larger fixed-geometry kits require a tune to control smoke, drive pressure, and EGT.

Installation notes

• Inspect before you install. Check oil condition and replace any contaminated feed or drain lines. If the old turbo failed, inspect the intercooler and boots for oil and debris.
• Prime the CHRA. Pre-lube the turbo and crank with fuel disabled to build oil pressure before first start. Skipping this step is a common cause of early bearing failure.
• Use new gaskets and hardware. Replace gaskets and crush washers, torque pedestal and manifold fasteners to spec, and use quality V-band clamps.
• Set up the VGT. On VGT turbos, complete any actuator learn or calibration and confirm vane movement without fault codes.
• Check for leaks. Pressure-test the charge system and inspect boots and clamps, since blown intercooler boots are a common source of low boost on diesels.
• Break in and monitor. Vary load for the first few hundred miles, idle briefly after heavy pulls, and watch EGT and boost on the first towing trip.

Common problems BD Diesel parts address

• Sticking vanes and actuator failure on factory VGT turbos, commonly from soot buildup and heat, which can cause overboost, underboost, and limp mode.
• High EGTs when towing, often a sign the factory turbo is running out of airflow on a tuned truck.
• Blown intercooler boots on Power Stroke trucks, which cause low boost, black smoke, and power loss.
