power difference from 94-98 and 99-03 7.3

I am pondering which year I would like to buy and it seems like the newer 7.3s have more torque/hp. was this all due to computer programming? also, my brother and dad both have 97 7.3s and I guess those were lower than the 95/96? I have yet to find a spec sheet for all the years of the 7.3, so if anyone knows where I could find one please let me know!

94.5 - 97 were BASICALLY the same.

Early '99 added intercooler, different injectors, different turbo.

Late '99 added different injectors, turbo and high pressure oil pump.

2000 and only 2000 had I think forged rods.

Stayed about the same till the end in '03.

95-96 were not lower numbers than '97.

Hope that helps a bit.

thanks for the quick reply! I meant that I heard the 95/96 were more snappy than the 97, but maybe not true. I've been reading that the pmrs were used starting in 2001 except for certain block numbers..

I can't comment on specific numbers and stuff cause I'm not the authority, I just like 'em lol.

There are some serious gurus on here that will be able to answer any question you can think of so just keep bumping your thread.


And welcome to the addiction...I mean welcome to the ORG

What JJ said is correct.

94.5 -96 were 210 or 215 97 was 225 the SD got even more of a bump in power I think by 03 some SD had 275, but it think that was only the manual. powerstrokes up until 00 had the forged rods. some 01 did too, but I don't know which ones

95 - 97 had 9x cc injectors. e99's had 120cc i think? and i think after that they were 140's. all e99+ were split shots. tehy also have an intercooler. more power stock, adn definitly more power chipped. the OBS single shots usually get better mileage. when the SD guys go to single shots they usually report better mileage as well.

Nope, backwards but it depends on the truck.
Most 94.5-97 trucks have 90cc AA code single shot injectors.
Late 96 and 97 CA emissions model trucks have AB code 120cc split shot injectors
E99 trucks also have AB's
Latee99-03 trucks have AD code 140cc split shot injectors
Single shots make more power (all the fuel is expelled in one shot), the split shots were introduced to lower noise and emissions (the split shot name is because there is a small pilot shot of fuel before the main injection event)
SD trucks also have higher voltage IDM's that improve throttle response slightly.
Oh and PMR's actually started in 00 some time for a short duration, then back to forged for a bit, then PMR's again.
