Turbine Housing Info: Most DPS Turbos come standard with a T3 Wastegated exhaust housing, which can be upgraded to the Turbonator VGT/INT Housing.  Our Wastegated housings flow approximately 22 lbs/min through the wastegate when it is open.  This is the eqivalent of having one size larger turbine housing at wide open throttle, with the spool-up and drivability of a smaller exhaust housing when accelerating.  The best of both worlds!  On 5.9 Cummins engines our testing has shown the our T3, wastegated, exhaust housings perform superior in all categories compared to T4 housings non-wastegated housings.  Our standard divided scroll turbine housings create boost nearly 100-200 RPM faster and flow equal to or superior to the standard T4 housings at WOT.  We also have our Turbonator® VGT housing available as an upgrade on most of our turbos, which improve spool-up another 200-300 RPM faster.

Why our Compressor Housing are better:

• Ported shroud inlet (unique design).
• More compact design for beter fitment.
• Triple barbed inlet and outlet prevent tubes coming off.
• Up to 7% airflow increase over standard Borg Warner Housing.

DPS manufactures (designs, casts and machines) nearly all of our own compressor and exhaust housings.  Designed with CFD (Computational Fluid Dynamics) software for improved flow compared to anything our competitors have. Our engineer staff knows how our products flow and perform, we don't just guess.

The DPS Turbos for 2003-2007 Cummins 5.9L 24V engineered performance and efficiency, are designed specifically for Dodge trucks of this era, ensuring a seamless direct fit. These turbos stand out for their variety of configurations, including options ranging from Stage 1.5 to Stage 9.5, allowing users to select the perfect turbo to match their performance requirements.
