Ok so these are supposedly great BOV's and you can get one super cheap, here's my question. What else do I need to get this to work? Should be starting my swap next week, will i need to get a unflanged hot pipe and buy a flange, should i have the BOV installed somewhere other than the hot pipe, or is there a compatible flange, like a greddy type s for example (that was a random example, not specific). Oh, and I want the BOV recirculated, not vented to the atmosphere.
