thanks for the info, really really helps....I asked the International dealer guys and they have no idea how to make these motors work better....thanks again. After I pass emissions test next week I will do the changes. When I install the pyro should I do it before the turbo or after, what are the max temps in each location?

The IH dealer doesnt like to do fueling adjustments, mainly due to liability. Your best accuracy is pre-turbo. There should already be a place to drill & tap about an inch above the turbo mounting flange. Max sustained for pre-turbo is 1300-1350, but you can run to 1500 for a 3-5 sec burst. Post-turbo temps are roughly 1000-1100, depending on how far down the probe is in the pipe.

The ones I suggested earlier will bolt right up to the manifold, and oil lines too. The fresh air side may need some different size hoses to finish it.
I dont have part nimbers, but applications to look at, and that's what a wrecking yard will go by too.
This also depends on what hp level you're looking at going with.
For the HX40, find one from an 8.3 Cummins, but at the next lower hp rating. If you're after 300hp, try to get one for 250-275hp. Much over 300hp you'd be better off with an HX50, which come on a Cummins M11. Same idea as the HX40 when searching.
The Garrett; look for one from a DT530, since they had the highest ratings. If not, one from a 250hp 466E will still work. You can modify the garretts like you can the Holsets with different size impellers and exhaust housings if need be.
My philosophy is get a big turbo and fuel up to it.

Thanks guys, the wreckers in my area don't have anything as of now, I will keep looking.

If I go with HX40 or a turbo from a 250 hp will I have more black smoke under load. Or will the larger turbo push more air in to burn up the fuel up? What is the max boost these engines can take as a work engine day after day?
Thanks

It'll have less smoke over all. The reason for the turbo upgrade is the intake side of things. The T04 on your 466 now has an impeller that's around 53mm, and the HX40 is 60mm(some may be 58mm, but still bigger). The truck I drive at work has been holding up quite well at 30 pounds for the past 100k miles of pretty hard use(10k miles a year). I would be comfortable with anything 45 pounds or less with timing at 19*. Of course, it takes quite a bit of fuel to get that kind of booost pressure.
