upgrades on the 7.3 diesel in 99

[7.3Diesel]

What were some changes done to the 7.3 in 1999 compared to the 94.5-97 7.3 Powerstroke? I know that the turbo was bigger. Thanks guys

The hpop is a 17* instead of 15*, the intake plenums are bigger, its intercooled, injectors are 140 instead of 90cc. I think I got it all.

Here is some good info on the changes between the years in question on the PSD. Take note even on the slight engine block variations between the years. http://www.forddoctorsdts.com/articles/article-06-08.php

are you asking about the early 99 or late 99 differences?

yea there was the 94.5-97 to E99 then L99

E99 has 120cc injectors, 15*hpop, smaller turbo than late 99, its intercooled, no mech fuel pump.
