Blueprinted also to some means that the all of the ports, manifold's, Headers and all are matched. My old Blueprinted and Balanced VW 16V GTI (former SCCA car) also had the deck milled, and the head milled to Factory Max's. The Bearings clearances were also opened up along with every little thing that would pass an SCCA tech inspection. I purchased it from the local VW Dealer who raced it for 1 season. I have to say that was the most fun car I have ever owned, to bad it was when I was young and did nott realize you cannot pound the car every single day. I did get 140,000 miles on it. That's not to bad considering it had 9,000 miles of track use when I purchased it. It was raced at Road America, Sears Point, Mid Ohio, and many other tracks along with competeing @ Daytona on the Big oval in the VW Cup series.
OOp's, I guess I was just supposed to reply to Blueprinting and Ballanceing.
