I doubt anyone would fake it to the extent that I can see by the pics that its brand new and genuine and not a repaint. It also shows the box it came in on ebay. Yes it could be done but why bother? last I looked it was selling for less than a refurbed one. I have never seen a refurbed one that has the bolt holes machined out after painting to bare metal, and cleans the underside back to bright bare metal

YBs were shipped out to the states for use in single seaters, they were not just intended for Sierras and Escos they came in all guises, Ford only pulled the plug in their use for road cars due to the recession in the mid nineties, they used the excuse of emissions, but the last small turbo YB met every reg under the sun throughout the world.
