The 04 is 305 HP and 555 TQ and 04.5 is 315HP and 600 or 610 TQ i think. Thats why the 04.5 some of them have the 600 badge under the 3500 badge on the side i guess.

04.5 (600) has a cat, the dreaded third injection event and computer controlled waste gate. 04s (555) get better mileage and have no cat. I thought the 04 HO and the 04.5 HO were the same internally with gallery cooled pistons, bigger oil pump etc?

Ok well I guess that "completely different" was a little stretch. Somewhat different physically and programatically. Modding physically is pretty much the same, but programatically quite a bit different. Results of the same mods seems to be different also.

The 04.5 has 325hp/600ft/lbs. Both have the on the filter LP unless they have gone out and then they moved them to the tank. The valves and seat upgrade is due to the higher temps from the 3rd injection event and the cat caused by emissions reasons. The 04 HO is the 305hp/555ft/lbs. Some one else will pipe in about the SO motors. Lower hp and Torque.
