7.3 Powerstroke Tech Articles

The 7.3 Powerstroke engine was introduced in 1994 in Ford F250 and F350 pickups.  In 1994 you could order either an IDI or Powerstroke version 7.3 engine.  The easiest way to spot the difference is by looking for the injection lines.  Only the IDI versions had visible injection lines running to each injector.

The 1994-1997 Ford 7.3 Powerstroke engines used a high pressure oil system to regulate fuel supply.  They had a mechanical fuel supply pump in the valley under the turbo.  These engines came from the factory rated at 210 horsepower and 425 ft/lbs of torque.

The 1999-2003 Ford 7.3 Powerstroke that came in the new Superduty pickups received larger fuel injectors and a wastegated turbocharger.  Horsepower was increased to 275 and torque to 525 ft/lbs.


The Ford 7.3 Powerstroke is a great engine with some proper modifications to address trouble areas.  If you have any questions about performance modifications, troubleshooting, or anything else related to the 7.3 Powerstroke, please feel free to give us a call at 1-877-367-9351.
