The 'Powerstroke' name has been applied to a few different turbocharged diesel engines. The first was the 7.3L (DT444e) - introduced late in 1993 when the 7.3 IDI (non-turbo) engine block was updated and given a turbocharger. It was sourced from Navistar/International.
In 2003, the 7.3L Powerstroke engine was replaced by the 6.0L (DT365) - and that soldiered on up through 2007. It was replaced by the 6.4L turbodiesel, also sourced from Navistar.
Beginning with the 2011 model year, Ford is now building their diesel engines "in house" because of too many warranty issues with Navistar. Their new 6.7L "Scorpion" diesel engine is a beast of a powerplant, and should prove better, quieter and more powerful than any other Powerstroke. Let's hope they are as reliable, too!
