You can put any BOV on any IC. I was reading the latest issue of Import Tuner, and they have an article about a shop installing a BLITZ FMIC on a WRX. In it, they said that they opted to place the BOV close to the hood scoop, so that the sound would be more audible. Since they chose the placement, that tells me that they can place it elsewhere, but why would you. After all, one gets a BOV so that he can hear it, so my advice to you is to keep it close to the scoop.
