The "Flex Tek" box is a nice idea, but fuel isn't the only thing that needs
to be changed...plus, $400-$600 isn't going to cover all the proper
conversion parts (let alone labor). I can see a conversion kit working if
you plan on only running E85 but what if there is none available in the area
you're traveling to - that's where the FlexFuel vehicles have the advantage
- sensors to detect the fuel type, PCM programming for the different fuel,
and actual materials used in the parts to prevent corrosion.

Here's one:
http://running_on_alcohol.tripod.com/id26.html

And another:
http://e85vehicles.com/converting-e85.htm

The main problems seem to be possible corrosion problems with components not

designed for it, and that you're not running a high enough compression ratio

to really take advantage of the higher octane rating of the alcohol.

Then there's this bunch:

selling a conversion kit. Might be worth investigating further if you were
planning to make this kind of switch.
