i'm not running one on a vortech, but i'm getting ready to do a setup for a buddies pax. novi 2k, and i'm running a setup on my custom T70 turbo setup.
I've got a ebay 33x12x3" air/air intercooler w/ 3" inlet/outlet w/ 3" cold side piping. Its extremely simple to do the setup and i recommend silicon couplers and T-bolt clamps. dont go cheap and use rubber couplers and worm style hose clamps. spend the extra $$ and get good couplers and clamps.
Theirs some good deals on ebay on some intercoolers, just make sure they are a bar and plate style and not tube and fin (basically a big radiator), as the tube and fins aren't as efficient as the bar and plate.
