I recently swapped out the engine in my 1988 Toyota 4Runner. It had a 3.0 liter V6 that got horrendous gas mileage, for a 3.0 Liter Turbo Diesel engine from a 1994 Toyota 4Runner from Japan. I had an air to water inter-cooler added and it set up to run 100% bio-diesel. We turned the fuel down a tad, and turned up the boost. I am sitting on 35 inch tires, because I love to go on offroad trails and go to the offroad park. I also have a K&N Air Filter and a 3 inch exhaust. I plan to do some more efficiency mods here soon, I am going to re-gear to 4.10 gearing, it currently has 5.29, which will mean a lower RPM at highway speeds, a belly pan / front skidplate, wakeplates off the back set at 10 degrees, possibly HHO injection, and am going to do some work to the injectors, just not sure what yet. The best mileage I have seen was on the highway at 58 miles per hour. I got 30 MPG on a flat road. My goal with the modifications will be for 34 MPG on the highway.
