I have been told that the stock OEM pulley with the correct tooth count and part number must be used on the new Ford. As far as the turbos, I have been though many tear downs and can tell you NHRA has all the specs they need to check the housings and cartridges. They check both wheel diameters and for clipping. The turbo must be completely stock as produced with the correct make and part number. Jim
