Good luck with your turbo build. I had an EG Vtec Civic about 4 years ago and I did the same thing. It was a really good experience and a lot of fun.
Recommendations:
Front-mount intercooler: If you don't have one, look for one out of a Mitsu Starion or Plymouth Conquest. They are the perfect shape for this kind of project. Let me know if you need intercooler or charge piping couplers, I have a couple feet of 3" left over.
Look to the Honda forums for help with this. There are an ass-load of people driving around in junkyard-turboed Civics. Try this site:
