Oh trust me i know how expensive ITB's with EFI can get, my next question was going to be "how handy are you???"
lol, I did a set-up on a Honda SOHC VTEC engine and added motorbike ITB's with megasquirt. Even with the mods to the fuel tank, addition of new line and a return line with the fuel pump, injectors and filters and the dyno time, I was into it for about $1000. I can't believe how much guys charge for EFI over there.
