Do any of you have a pic of where this part goes when replacing the stillen unit?

I can take a pic for you a bit later today, but if you look under the charge pipe about 12" away from where it connects to the supercharger outlet, you'll see the recirculation hoses and the plastic bosch/denso BPV. It's a very easy swap and I didn't even have to remove the charge pipe completely to access the area.

Will be taking the z out for a drive in about half an hour, will post my conclusion!
