what type or kind of blow off valve should i use with the v2 sc? and where can i find them online?

 

You can find them everywhere actually. Even eBay has them for decent prices. I like www.gruppe-s.com . As far as the actual BOV goes, most people tend to enjoy the HKS SSQ the most. However, the Blitz, Greddy, APEXi, etc are very reputable as well.....(some GReddys have been known to leak though.

 

Greddy...

 

but do i need a universal bov or do they make them to fit the flange already on the v2 piping?

 

Blitz fits w/o modification.

 

The only BOV that I know of that needs a different flange welded on is the actual HKS SSQ. It requires the flange in order to go on right. But, it is only around $40 or so lol....
