Well the biggest reason why I got a 4Runner wa to go up to the mountain in the winter and go snowboarding, but after going up to the mountains for the first time I found a LARGE lack of high-end torgue (correct me if im wrong) on going up steep hills in my 2.7L. On most of the very steep hills i had to pust the gas peddle all the way to the floor. My question is what are the mods that I can make my trcuk go up hills easier on the freeway. It dont care about the price, I just want to see what mods are out there. It would mean alot.

 

High end torque usually implies in the high end of the rpm band. You want "usable" torque in the lower part of the rpm band.

Mods that will make you notice a difference when going up-hill: turbocharger, supercharger, bigger engine.

 

Intake, Headers and Exhaust work along with some engine tuning would help as well. Maybe a new CAM, too.

If your going to do all that just get a v6. Not only are the parts to do anything going to be expensive, labor will be a bitch and a hassle. Just a thought.
