Welcome Josh!
The Sporty has had radical work done to it by Dave of Rocksportgear, and I know that at one time he was looking into double transfer cases. He probably has more experience than anyone here on the forum on what can be done.. As far as a V8, my experience has been as long as you have deep pockets, most anything can be accomplished. <img src="/forums/images/graemlins/cyclops.gif" alt="" /> YouTube has a few videos that have some wild Sportages.
I also know that our current moderator had plans to do some upgrades. Maybe he can give you some pointers.
Hope you keep us informed on your rigs progress.
Everet
