The Third Generaton Ford Diesel

In 1994 the 7.3L changed quite a bit. Although the previous 7.3L had the same displacement, there weren't any other similarities between the two. The Powerstroke is an electronically controlled, direct injection engine. This engine produced up to 250 hp and 505 lb-ft of torque in automatic transmission trucks during the last years of production, and 275 hp and 520 lb-ft of torque in manual transmission trucks. The 1994 to 1997 direct injection (DI) Power stroke had hydraulically actuated electronic unit injection (HEUI) fuel injectors and ran a 15° high pressure oil pump (HPOP) to create the necessary oil pressure to fire the fuel injectors. 1994 -1997 trucks used a cam driven fuel pump, whereas the 1999-2003 trucks used a frame rail mounted electric fuel pump. It uses a single turbocharger. In 1999, an air to air intercooler was added to cool the charged air from the turbo making it more dense. The cooler, denser air would increase the horsepower potential of the engine, while also reducing exhaust gas temperatures (EGTs). The 7.3 L DI Power Stroke was in production until the middle of model year 2003 when it was replaced by the 6.0L. The 7.3L Powerstroke engine to this day is one of the most sought after and reliable diesel engines ever produced.
