Good to know, thanks

I guess this only applies to forced-induction engines because intake temperatures are higher even after an intercooler.

EGR only helps by warming up the engine faster, beyond that its no good.

Again, good to know, thanks

A turbocharger would definitely improve engine characteristics in means of power, it was the first idea that came into my mind when I thought of engine tune-up. But in this case I'd like to focus on fuel efficiency rather then on power (it does not mean I am willing to sacrifice any, it's just not a #1 priority). I guess a turbocharger will not help efficiency much, right?

As said before, it's a military vehicle, it was designed that way. Take a look at HMMWVs - they output 190hp out of 6.5l AFTER turbocharging, and don't have too much torque either. These engines were meant to work with sand in the intake, water in fuel and 1/3 of oil they usually run with... So, it's not the age we are dealing with.
It's fairly obvious that fitting in a complete modern engine will get the best results. I was just wondering why this particular engine consumed that much and what the consumption would be with a different engine.
