Also, the more I read the "STi Forum" the more I realize that you people need to look at the rest of this website more often. This EXACT question has been asked an answered more times than even god could imagine. Same goes for any question about an exhaust system. Try that searching that lil' guy down there named "engine performance."

You mean theres very little need for a sti forum!!! No way

Edit: oh and these problems may or may not show up after several months of problem free use.

Yup. BOV on WRX or STi = BAD IDEA. Try a bypass valve instead.

Has the thought come up already?

[afpdl]

Yup, I think there should be a 2.5L ENGINE forum only. Everything else fits fine with the rest of the forums.

very true, good idea.

I heard that on the WRX if you dont get a recirculating bov then your car will run realy rich and crappy. is this true

[crazycam31]

Not always.... It seems that some cars do this while some don't. If you do a search you can read TONS of arguements from both sides and personal experiences. I personally have a 100% atmospheric one with no problems.

I have an rfl bov and it only gets a little rich after shifts. Usually a little pop of unburnt fuel exiting the muffler. Other than that my car runs fine.

While some people claim to have experienced problems, most of the world is just fine w/a 100% atmo BOV. Basically the worst thing that should happen is that you'll shoot more flames out if you're catless. As long as the BOV isn't leaking air at idle or under boost, there is absolutely no reason it should affect MAF readings anytime but between shifts...

What do you need a BOV for I thought you had a 1993 2 door impreza

I've noticed that some Japanese shops use a BOV that makes a fluttery noise. Can anyone tell me who makes them?
