Completely different. I'm sure some of the components are the same, but the 94.5-97 powerstroke is a mechanical fuel pump fuel system and the 99 and newer have an electric fuel pump in the tank. Also, the 99 and newer are intercooled. There is quite a bit of difference between the engines. I'm sure someone else will be along to give you some more info.

the turbo is different and there are a couple of things switched around like the a/c compressor and the alternator r switched places. the internals r the same except for the injectors and on the 01-03's the rods are made of a different material. and the HPOP is different on the newer ones. just some lil things that r revised from the OBS trucks.

The base engine is basically the same and I think is interchangeable, its all the stuff that’s bolts onto the engine and the truck that is different.
Biggest parts that come to mind is;
Injectors,
Intercooler
Turbo
Fuel pump
Rest of the truck

Of course you got breaks in the years too, most notably the early 99 which is kind a bastard child. But I like mine cause I dare to be different.
