I have a custom kit I made (see how-to link earlier in thread) using a vibrant core, and CX racing piping. the whole thing cost me a little over $225, and maybe 10 hours of work.. it could be done in much less if I mounted the core differently (I had to fish the bolts into the crash bar because I didn't want to drill all the way through both sides) actual pipe routing only took me maybe 5 hrs, with nearly only hand tools.
granted, I scored the core locally for cheap, and it is smaller than most on here like using, but at such low boost on such a small turbo, I don't see the point in a huge core, and I value keeping my engine cool, not just the intake charge, so leaving that air for the radiator doesn't bother me.
