Lots of great parts and info for Hondas comes from the DSM crowd, eh?
You're gonna love that BOV unless it leaks. If it does I have a free fix for you. Crush it slightly between two blocks of wood in a bench vise. They've been known to hold 24PSI rock solid after such treatment, but don't do it unless it's leaking air out at idle.
I'm going to have to do the DIY on boost leak testing. It's the single most overlooked tuning problem on turbo setups. It wreaks havoc on cars that have mass airflow sensors or vein pressure controllers, but it shortens the lifespan of your turbo no matter what setup your car uses to meter incoming air because the turbo has to spool to a faster speed before the intake charge reaches the wastegate spring pressure. Not good.
I haven't had the time to test mine yet, and will be doing it maybe as soon as tomorrow. I could take some pics and do a how-to. I have web space to host it. I asked if it would be helpful before and got no response. Here's a tool I made to do it with... costs about $15 to make. HomeDepot or Lowe's performance shops (plumbing department) carries most of what you need to make it.
