Forged vs PM rods? I think 99 and up block has more webbing.
Not shure of year changeover on both.

yeah ,there are a few more differences but i'm not sure on the exact change over dates, the 99's should still have forged rods in them all the way till 01.
i beleive the 99-03 turbo wheel pushes more air, thus the reason it will surge at higher boost levels, the wastegate blows off excess boost to keep from damaging the turbo and engine. the 99-03's used a physicly smaller turbo housing then ours so they had to add the wastegate so it wouldnt overboost.
the idm is your injector driver module, the more output voltage the better the injectors function. the superduty module is direct bolt in to our trucks.

pop your hood and note the output to your turbo, its a black y that goes directly to the intake, this is refered to as a hot air motor. the intercooled trucks run the air out of the turbo and through an intercooler to lower the air temp before it goes into the motor, colder air is denser so you can throw more fuel in the cylinder to get more power, yet run as efficent as a hot air motor

No work bolt in? none. With a few electrical swaps (VC gaskets/sensors) a long block (block, heads, pan, and valve covers) any 7.3 PSD will go in as long as you have an electic fuel system ( or swap cams) cause the 99-03 motor don't have a lobe on the cam for the fuel pump. Also you would be best to swap the intake plenum's and turbo/exhuast plumbing pre turbo.

so the IDM is a direct swap from 99-03 into our trucks?

That is correct. You will get a 120v IDM from a SD. Do the mod and get 140v.

You may be able to find a cheap one in a junkyard.

so the 99-03 SD bolted in our 97 PSD's will change the voltage or do you need to make changes?
