Easiest thing to do would be put the tallest tires possible on it. If it is stock height a three or four inch lift would give you more room and not be hugely expensive. There are lots of tire speed calculators on the interweb you can use to research how much change you will see. Plus they would be easy to resell later. You didn't mention if it is a manual or auto tranny. Or what transfer case you have. If you have an automatic a later model 700r4 swap may be the way to go and it may work in your long term plans. These guys are Jeep guys but the site is full of information.
