Sounds like an 'interesting' but smart way to go about it, i am still smoothing and working on mine till i think it is fit to go on the car. i'm sanding it back and polishing it up, i will have a pipe welded in for the ACC valve and the bov mounted under the wheel arch, then i will thread a nipple for the boost controller, unless i get a kkr480 which dosen't exactly need a boost controller. cheers, hame.
