Brett,
Same as the original bov, but you will have to get a plate tig-welded onto the ic pipe to bolt up to. Hook both side discharge nipples together with a hose and just run the vac source line into the top.
Ive only run stock boost levels with it and took some time to get dialed in. Talked to the guys at xs engineering about it and they said they havent been able to get it to hold boost levels over 15 psi without shimming or rigging it.
May be in your best interest to ditch this thing if you're planning big boost numbers. Im planning on dumping it in favor of the tial bov.
I will email you a pic as we cant post pics freely on this board.
Hope this helps.

I guess maybe I will look for another BOV if it can handle high boost. I want to run about 17-18 psi. I like the Greddy BOV that SFR sells. But I would have to get their IC pipes... not really a bad thing is it?? <img border="0" title="" alt="[Wink]" src="wink.gif" />

I have one and it work great. I don`t see how it could not hold more then 15psi because. The valve opens against the outcoming boost so the more boost you run the more it stays closed.
Also this bov uses psi to creat pressure in one chamber to help it open and react extremelly fast.Thats why it a twin chamber bov.
As for adjustment it pretty easy. You just need to adjust it so it will open when you get off the gas even at 1 or 2 psi. This way you don`t get you boost bounce back into the turbo. This is what you have to do with all adjustable bov and dv valve.
For instalation i was lucky. I got it from a local speed shop that is a Apexi dealer and they had one for a 3gen Rx-7. And the adapter in the box work for are 951. Look at the picture here.
