don't really see the point of importing a klze unless your staying na really. need a bunch of electronic goodies to go with it and the cost would get pretty high. especially coming from a non v6 car to begin with.
still looking forward to this build. I don't know if ill do this myself or just build a fs, but i might come harrass you for some mega squirt tips as i might go this route with a pre-assembled board.
