So, E85 as a fuel, if you understand what it offers, is a wonderful thing. There are benefits and tradeoffs:

Benefits:
1. More hp/torque
2. Cooler running
3. Better for the environment ("green")
4. Typically cheaper than most fuels

Tradeoffs:
1. You burn more of it - close to the same amt at idle, up to 33% more at WOT than gas
2. You need specific changes to your computer to get the most out of it - specifically you'll need to change your fuel curves and most people don't have the know-how to do it
3. You can't get E85 everywhere. In my Mustang, I have to plan trip segments *VERY* carefully, and forget cross-country driving, unless I pull a tanker w/my own fuel.
4. E85 becomes E70 in the winter, which means yet another tune

Overall, I'm REALLY happy running it in my Mustang - street/strip that doesn't get driven more than 100 miles from my house. I'd have a tough time considering it in a H2 and the concerns if I could find E85 fuel when driving cross country.

If you think some "kit" will magically cure all the above, it'd likely be more than just replacing the engine with a flex-fuel one that also includes the gas/E85 sensor (finds the % of each fuel) and then adjusts the fuel map as a result.

YMMV.
