Isnt the bov on a 02 wrx actually a BPV? well i was wondering if anydoby ever messed around with their stock bpv and modified it to be a bov? by taking the recirculation hose/tude off? i did this yesterday to see what would happen and what i found out was it doenst work too well. it is really audible compared to stock bpv almost sounds after market. when the car would idle it would drop in to low rpm and die. when you get on the throttle it would hessitate a little. anyone ever try to plug the recirculation hose/tube off? then maybe it wouldnt studder and die. cause on some after market bov's they dont use the recirculation tube/hose. any ideas???
