I'm with bill... using mostly stock components with enough fuel and something like Megasquirt to control fuel and spark and you'll most likely end up close to all goals and fairly reliable.. Its kind of an even balance between the 3 situations I posted above.. Where you'll be paying big time is.....

Time finding all those parts...
Putting it together...
Troubleshooting whats wrong..


For Bill and most full time mechanics doing this stuff is easy. but its not something I'd like to deal with personally, however I'd be much more inclined if i lived up north or in ireland. I hate the heat and love the super cold
