    you have a broken BOV. get a new one

    HKS SSQV will cause turbo lag between shifts; there is no recirculation. I had the BOV and it was cool for the sound, but definitely made the car more sluggish after a shift. I sold it and put the stock one back on. With the silencer removed I could hear the turbo more and also the BOV, which was satisfactory for me.

    The only time you really need to replace the BOV is when you are pushing so much boost and the stock BOV can't hang anymore.

    Save the money and spend it on a downpipe

    Yes, it will fit. BOV's are universal on the different model year WRXs. The only difference is that some front mount intercoolers use specific blow off valves that will only fit those FMIC's.

    Did you hook up the line to the back of the BOV? Did you adjust the bolt on the back to loosen the spring tension?

    fwiw, i often run 20 psi on the oem turbo, spools at about 3k. it holds it rather well through the midrange, starts dropping off at and tapers itself down to ~15 psi at redline. mods on www page. in the colder weather i generally dial it back a pound or two.

    bov installation for 05 STi

    this isnt for me, but my friend got a 05 STi like a week ago and got a p.i.t bov. he's about to install it but wanted to know what you do w/ the big hose (im guessing the hose that recirculates the air into the intake?) because there isnt any place to slip it into on the bov. do you just plug it and leave it?

    Actually it's not your turbo that could potentially be damaged, it's your engine. BOVs starve your engine for air and cause you to run rich in between shifts. Most of the time this isn't an issue, but it can cause some slight turbo lag and occasional engine stumbling between shifts. Most people don't find it annoying enough to take off the BOV. There are some 50/50 valves out there that recirculate and make a noise too, but I couldn't tell you how well they work. Do a search, there are 9 zillion threads on this subject.

    so you're saying its not 100% for sure my car will be screwed if i get one. i keep thinking that if i get one, there goes scoob just because of a BOV and i fear that even if i take it off and put the stock pressure-relieving system back on subaru still wouldnt fix my car cause they'd know

    I am pretty sure that the STI bov setup is exactly the same as my 05 Wrx. If it is a recirculating Bov then it should be plumbed back into the intake, but if not then yes you should plug the opening. I know there are other threads talking about plugging the tube with a shower plug etc. Once it is plugged if its possible to put the hose clamp back on it would be a good idea, however when I had my Bov installed I didnt do this and it was perfectly fine. It should be a very simple install and I hope that I answered your question.
