Tuned For Flow And Built To Perform

The BD Diesel 1045911 turbine housing is a 16cm non-waste gated, dual throat design specifically engineered for 1988-1993 Dodge Ram 2500 and 3500 models with the 5.9L Cummins engine. By replacing the larger and slower-spooling 18cm or 21cm factory housings, this part increases exhaust gas velocity through the turbine, resulting in quicker spool-up and a more responsive turbo. The dual throat layout improves exhaust flow balance, which helps maintain boost stability and reduces backpressure at higher RPMs. This housing is not equipped with a wastegate, making it a solid choice for trucks that rely on mechanical boost control or are set up for off-road and performance-focused builds. The precision casting ensures durability under high-heat conditions, and its EPA-compliant status makes it federally legal in most locations outside of California. Whether you're fine-tuning an existing setup or refreshing an older turbo system, this turbine housing offers a noticeable improvement in how your engine builds and holds power. It’s a high-efficiency, low-complication solution for getting the most out of your turbocharged Cummins.
