any one know if its a fake/ripoff or is it worth getting?

I have used both ebay intercoolers and bovs. Intercoolers are ok, bovs are junk. The machine work is terrible, they either get stuck open and leak or get jammed closed and don't open. I would recomend staying far, far away from them.

That one doesn't look to great. I actually bought one from ebay, but it was a greddy and its been great. Most good bovs are around 170 alone which is where i would shop for when trying to find a good one.

I have an extra greddy i should get rid of for 160

BOV's are gay. Run without.

^^ Yea for an n/a.

No... FOR A TURBO... You don't NEED a BOV..... and whoever taught you that is trying to sell a BOV.

Well... its not completely necessary. A recirculation valve is more efficient than a blowoff valve though. Its basically a blowoff valve that recirculates the pressurized air to the intake of the turbo to help keep it spooled up between shifts. You don't get as much of a pssshhht sound, but I think that noise is ricey anyway. But bottom line is that even with stock boost pressures, I would feel more comfortable to have some sort of overpressure protection for my turbo/intake tract when my throttle body butterfly valve slams shut.

there should be a sticky regarding ebay stuff because i cannot count the amount of times i have seen similar threads to this...

micah

If I were to go turbo again (no money atm), I would definitely go recirc... The pssshhht sound has been ruined, tainted by the "scene".

I definitely don't know enough about this to start talking in high detail.. but.... There was a thread recently that talked about this I think........ can't seem to find it though. Might be on a different forum. Made me a believer of BOV's being mostly marketing puff. If I find the thread, I'll post it up.

I thought recirc valves were only used when motors' mafs needed to count the extra air off throttle to prevent a rich a/f mixture(EJ20's, EJ25's 4G63's etc.). I thought that was usually just a factory embedded tune and that most aftermarket ems's can help compensate for the need to recirculate and go open atmsphere and some people just continued to circulate for reliability issues.

You need something unless you want compressor surge to kill your turbo.

How many turbo failures have you seen that were directly caused by surge?

None, because they all use blow off valves. Noob

Will it hurt a few times? Probably not. Will it eventually destroy your turbo and cause the turbine shaft to snap? Yes. Not to mention when your turbo is spinning and you suddenly slam the throttle plates closed all that boost is forced back towards the turbo and it slows down your turbine rpms, slows boost response, and can increase lag from a Wot to closed to Wot throttle situation (ie changing gears).

Blown turbo = natures way of telling you to upgrade. Now shut up and sell me your front bumper!

gross polluter

I'll take that as a "NO" then.

Have I seen anyone I personally know? No. All my friends with turbo cars all run CBV or BOV's. Every car with a factory turbo has some sort of compressor bypass for a reason. Have I seen pics, vids, and real life evidence that I speak the truth? Yes.

gross polluter

You sure about that? What about 2.3t fords that go 200k miles without one? You don't think that factories use it for response?

Beats me, everyone factory turbo car I've ever seen has one.

I think the cheep IC will be ok but if i go for a BOV on eBay it will have to be a real brand something descent.

BOVs on ebay are pieces of crap. Get a brand name one, other wise, it'll leak or jam after 2k.

yeah that blow off looks cheap, too cheap. I love my old blitz ss bov, its loud, plus the piping came with a really neat marble paint looking finish. I'm a firm believer in running a bov or recirc valve, they're the same to me, just one vents to the atmosphere. the purpose is the same, to preserve turbo life, it's similar to a turbo timer in that you don't need one to make the car run but it can't hurt to have one to help your turbo.

maybee

that BOV looks like a -EV decision
