In case anybody needs these
7.3
The first 7.3L was produced from 1988-1993. The original 7.3L diesel was a non-turbo charged indirect injection (IDI) engine, followed shortly after by a turbo charged version. It was very similar to the previous 6.9l IDI diesel engine, which was simply bored out for more torque. This engine is not considered in the powerstroke family. In 1994, the 7.3L underwent some changes. The 7.3L was changed to a direct injection (DI) engine from the original IDI engine.<SUP class=reference id=cite_ref-powerstrokediesel.com_0-0>[1]</SUP> Ford also added electronic fuel injectors and gave it the name Power Stroke.<SUP class=reference id=cite_ref-powerstrokediesel.com_0-1>[1]</SUP> This model produced up to 250 hp (190 kW) and 525 lb·ft (712 N·m) of torque. The new 7.3L DI Power stroke had "single shot" HEUI (hydraulic electronic unit injectors) fuel injectors and ran a 15º high pressure oil pump (HPOP) to create fuel injection pressures. The turbine housing was a 1.15 A/R. In 1999, an air to air intercooler was added. The intercooler cooled the charged air from the turbo making it denser. The cooler, denser air would increase the horsepower potential of the engine, while also reducing exhaust gas temperatures (EGTs). The turbine housing was changed to a .84 A/R housing and a wastegate was added. The "single shot" HEUI injectors were upgraded to "split shot" injectors. With larger injectors, the HPOP was advanced to 17º to increase fuel pressures. The 7.3L DI Power Stroke was in production up until 2003 when it was replaced by the 6.0L. In 2003 Ford Motor Company split the year, early 2003 the 7.3 DI was available, and the later part of the year got the new 6.0L. The 7.3 IDI and 7.3 Powerstroke are not the same engine at all except manufactured by International for Ford. This is known to be the longest lasting and most reliable powerstroke engine.
