Funny thing about the new (to us, the U.S.) Fiesta...
I had a 1978 Ford Fiesta, in about '84-85. It got better gas mileage than the new one does.
Me & Popdigr put a two-stage (works like a four-barrel) Weber carb on it, and it ran like a raped ape. The rear axle was just a tube, so, we had the welding shop put us some rotors and disc brake set up back there, and ran them with a second manual master cylinder and a dual linkage w/a proportioning valve. Filled the front half of the original, and the back half of the second master cylinder.
That 1600cc German engine was sweet as hell. 0-60 in about 6 seconds-flat, and stop on a dime and give you a nickel back.
