My Challenge to U /6ers....
have you thought about a hydrogen conversion? theres some good website around that have some good cheap way to go about that with a home built setup that uses water and electrodes to produce the hydrogen, very scientific and clean burning. then from there throw on a junkyard charger or blower and call it a day.
google automotive hydrogen conversion
disclaimer!!! im not an engineer but i looked into this afew years ago for another car, never ended up doing it though, this is the info i gathered.
