this is for road racing, and the class he runs inn pretty much limits anything to th eengine, I know ITS and ITA will only allow you to rais the compression half a point max but Im pretty sure power adders beyond that are banned, the colored lines appear to be fuel and the big lines in back I would assume were break ducting although I dont see a functional opening in any of the pics, if your referring to the orange tubes in the front and rear those are the remote reservoir for the coil overs, John can correct me if im wrong on any of this
