blow off vale

95 850t auto, want a blow off valve but cant find one for vovlos, where at can i get one, how do i install it and how much.....

Did you maage to find a blow off valve, coz I'm interested in getting one too?
Thanks.

Volvos use a CBV not a blow off valve. You have to get a blocking plate to block the CBV. You can use a universal BOV and weld it to the intercooler piping. There's tons of info on it at volvospeed.com/vs_forums. It's pretty simple. The block off plate cost $20 or so.
