you could do an air ram intake, just direct the air from the outside of the truck, search the form for that and you can get pics of what other people have done for ideas.

The cheapest way to get the most power is to look for a second hand turbo kit. I got an incomplete kit for $200 (had to fab the downpipe and crossover pipe). But usually they are in the $500 range. If you are patient the right deal will come along.
A ram intake will help, but to really make a difference that will let you hold those long hills on the highway, a turbocharger is the only real significant difference you are likely to find.
