it depends on which style bov your running.

for styles like the greddy typeS or turboXS type H-25 - they simply plug into where ur bpv is.

for styles like the hks ssq, and "other" turboXS one (the one on the right of don's post) - you need to get a little more creative and get a adaptor or a custom flange. you could also mount these on ur ic return hose (you'll need a custom pipe with the flange welded on), this will run in conjunction with your bpv.

email me if your interested in the second style with the hks, i believe we have a few kits still on the shelf.
