Can You Replace Stock Gtr Bov With Single Atmospheric

[Daz]

hi i was just wondering if i can replace my gtr bov's with one atmospheric one or do i have to have 2 of them

[joeyjoejoejuniorshabadoo]

only if your ghey

[TTT]

don't listen to him..

yes you can replace with just one.

you'll need to make some sort of adapter up though.

I'll buy your shitty stock ones for $50.

that should be enough to have a custom, shiny metal adapter plate for your single atmo bov.

I would imagine just fitting one and blocking the other off as if you wanted to do the flutter it would work. I haven't actually seen the piping of the GTR and thought about it to really say.

Edit: Just realised there was no point to this post.

You can do that no worries, but remember its one pipe going into two bov's. Not two pipes, so all the air will just be fed to the one bov. You usually put two on as a better attempt to vent all the air. Putting one atmo bov on will just make it work harder and possibly not vent enough air so the excess would be sent back to the turbo charger and you would experience the flutter noise.

thanks for the info guys. I dont want to change the bovs by choice its just that i have bought a hard pipe kit for my gtr and the pipeing kit does not have provisions for the bov's to be plumbed back so my standard bov's are venting to the atmosphere at the moment and i think this is why i have poor idel and boost response takes a little longer to come on

Id say your problem is more likely attributed to the fact you're venting to atmo, not that your using stock BOV to do so.

IE stock or aftermarket, without a retune your still going to have the same problem

[Sydneykid]

GTR stock BOV's are better in every way than almost every aftermarket BOV I have ever tried. It's a 99.9% guarantee that it won't matter what BOV you use, you will still have the same problem.

so do you think that the problem may be able to be tuned out using power fc or do i have to find a way to plumb the bov's back in?????

[TTT]

if your car still uses AFM, then they have to be plumbed back in.

the factory ones do not stay shut at idle.

so essentially, you have an air leak.

un-metered air entering your engine.

a:f mixture is screwed and you get idle/stalling issues etc.

my GTR come from Japan running the Greddy Type R single BOV without any issues.

[Daz]

thanks for the info what if i buy some atmo bov's so they stay shut at idle do you think that may solve the problem with a little bit of re maping

[sh@un]

If you are still running air-flow meters, you need to plumb the BOVs back to make the car run properly. no ifs, no buts.

If you have MAP fuelling, feel free to go nuts with BOVs that vent to atmosphere.

[TTT]

there are people who have atmo venting bovs on AFM equipt GTR's with no problems.

but there is always some tuning to help it.

I'm not sure of the exact parameter that needs to be adjusted but it would have something to do with overrun fueling or throttle closed fueling or something that describes what the ecu does when throttle is shut.

basically, you want to remove fuel at that point so that when the atmo bov vents the air out of the system, then the ecu doesn't inject the fuel it was going to, that would have mixed with the air that was vented.

My GTR came over with twin atmo Blitz BOVs, no major issues - just runs a lil rich between gear changes, but I would of kept the stockers if I had a chance.

btw the newer hks ssqv for gtr comes with the adapter/replacement pipe to suit single atmo bov.
