* 5.9L Cummins: Generally used a single, variable geometry turbocharger (VGT). The specific model varied slightly depending on the truck's trim level and options but it's essentially one turbo with adjustable vanes.
* 6.7L Cummins (introduced late 2007 as a 2008 model): While some late 2006 models might have started to see the 6.7L, they were uncommon. The 6.7L, when it fully arrived, used a single, fixed geometry turbocharger. However, later iterations of the 6.7L (post-2006) would move to VGT or even twin-turbo setups.
Therefore, to know the *exact* turbocharger on your specific 2006 Dodge Cummins, you need to determine your engine's displacement (5.9L or 6.7L) – this information is usually found on your engine block or vehicle documentation. Even then, you'll likely need to look up the specific model number of the turbocharger installed based on your VIN or other specifications.
