I've been trying to figure out which BOV I shound get, or if I should get a recirc valve. The spec shop has HKS SSQV BLOW OFF VALVE for $199.95 but that seems a little steep. Also from what I understand to install it requires cutting a hole in the intake tubing and welding a flange onto it. Anyone who has experience with this please give me some ideas. And yes I searched the forum but I didn't find anything extremely useful. Mostly I just want to know which BOV to get, and the best way to install it. Also I need to know which POV's are good, and the best way to adjust them. I was thinking Greddy's POV. Much Thanks.
