Its not likely to be feasible at all, and you'd net bigger gains for your dollars by just doing a custom turbo on your 2.0. Really, the BEST use of your dollars would be to sell what you've got get a used V8 Grand Cherokee of a similar year, if you really need more speed/power. It would for sure cost you more money to do engine swaps or turbo than it would to just get a more powerful Jeep. I know that's not the answer you want to hear, but those are the facts.
