nice... does anyone remember a K Car with a supercar engine? that was not quite as crazy as this one, no jet engine, but it was nice. i can't seem to find it but i remember reading about this "sleeper car".

My favorite is the Ariel Atom V8, which swapped the Honda Civic engine for a hilarious 483hp 3L NA V8. In a 1300lb car.
