We recently parted out a 1993 Miata that came with a complete Sebring Supercharger Kit. The car had 110k miles at the time of dismantling, but we are not sure of the mileage on the kit, or how long it was on there. These are the "old school" kits that were available before they were later turned into Jackson Racing branded kits. Everything that was installed on the car was removed and kept with this kit, but you may still need an odd bolt or clamp or two to complete installation. In good working condition, with no odd noises.
