I was considering Greddy but I'm just to cheap. What kind of decent OEM BOVs are out there guys? I'm switching from a TurboXS. Going to go with a recirculating setup to keep things more on the downlow.

I've seen the Bosch from several turbo cars are popular. Any others out there?

bosh

they came on the 900 saab turbos. you can find them used for like 25 bucks. just search on the internet and you can find it.

 

The 1st gen eclipse turbo bovs work well too. I got mine for $25 used.

 

I used the turboXS type H Bypass version...works wonders

 

Thats what I use.
By the way, if you want quiet your BOV then just plum it back into the intake tract. It'll also keep the turbo spooled between shifts!

 

How does a recirculation system work? Does anyone have pics?

 

Instead of venting the air to atmosphere, you need a BOV with an "output flange" so you can route a hose from it back into the turbo intake. This way you shouldn't hear the pssshhhh.

 

OHhhh...so, you have a hose going from that to in between the air filter and compressor?

 

Exactly. That's not the way mine is now, but with an OEM BOV from a factory turbo car or an aftermarket that has a flange on it will work that way if you want it to. For those interested, I have found a couple of really cool aftermarket Bosch replacements. Not nearly as cheap, but very nice.
