Good luck on the stock piping. I know that at least a couple pieces of the intake a no longer available.
Do yourself a favor and come up with a list of exactly what stock parts you're missing to get the car back on the road and livable on a daily basis. For this intercooler piping, do you need the piece that goes under the core support on the passenger side or that goes through the core support on the driver side? If you don't know the exact name, be as specific as you possibly can. Don't be afraid to take cell phone pictures if you have to, email them to yourself, and then upload them here so we can see what you're talking about.
When you've got your list, make a WTB post and list 'em all out. This thread has a whole lot of detailed talk about which turbo this or BOV that, but then the troubleshooting seems a bit thin. You'd be hard-pressed to beat the level of expertise on this board. Step up the effort just a little bit and watch the magic happen.
