Hello,
Can someone give me the lowdown on all of Ford's more recent diesels...
1. What year did it switch from 6.9L to 7.3L
2. When did it become the Powerstroke
3. When did Ford's diesels become turbocharged
4. how much boost from the factory, and
5. what were the power ratings for all of them

Thank you much for any responses.

1. The 6.9 was introduced in 1983 and ran until 1988 when the 7.3 debuted. Both of these engines were IDI (indirect injection) The 7.3L IDI ran until 1994.5. It could be had as either a normally aspirated engine OR a factory turbo option.

2. The 7.3L IDI never became the 7.3L DI PSD. They are two completely different engines. But the PSD debuted in 1994.5. All three engines were available in 1994. The 7.3 N/A IDI, the 7.3 turbo IDI and the 7.3 PSD. The 94.5 PSD was only available in a 5 spd.

3. The turbo was an option beginning sometime in the later 80's on the IDI's

4. Boost numbers were low on the IDI's, but they were a much higher compression engine. Boost would run in the 5-10 PSI range. PSD's from the factory would push about 15-17 psi boost.

5. 6.9 was good for 170 hp and 325 tq from the factory. the 7.3 IDI was good for about 185 hp and 360+ tq in the non-turbo and about 190 hp and 390 tq on the turbo'd unit and the 7.3L PSD was good for 215 hp and 425 ft lbs tq. Later PSD's came in with as much as 275 hp and over 500 ft lbs tq off the showroom floor. The 7.3L PSD ran until 2003 when the new 6.0L debuted.

Kevin,

You could possibly (probably) be right, I took a wild stab at that off of memory and was thinking 88-89 with the 7.3... but I was pretty young then still and more interested in small block V-8's and blonde cheerleaders.
