I think I will have room for an air/air inter-cooler. I even have one left over from the diesel.

I have bought water/alcohol injectors for my two diesels but have not yet installed them; it is tough finding a place to carry water.

The only experience with adding a turbo I have is with my one diesel 7.3 IDI in a 9K# van. On that one it made a huge difference, and it has never made 10# of boost. I also have a 2001 Power Stroke in an 11.7K# van, and it can make about 15#.

The vehicle is being set up as a tow vehicle. It will probably never see 5K rpm. The turbos I have supposedly come in early. Can I be expected to notice 5# boost?
