It is probably for recirculating your bov my friend.

^Not quite.

OP, is it an s14 sr? Only intercooler kits for the S14 sr have this. Anyways, that's for the factory BOV. HKS and I'm sure others have a universal flange for this. If you bought a fake SSQV then you most likely already got one. I'm finally getting around to having the flange welded on properly. You can kind of see mine in this picture:

yes its an s14 with an s14 sr. i have a greddy rs bov but its on the hotside...
can i get rid of it? i dont want it rubbing with the radiator lol

another question lol
why do some people put the bov on the cold side and some put the bov on the hotside

[Hoffman5982]

No you don't need it since you have a flange welded on already.

As for hotside vs coldside, it's all preference. Some will argue that one side is better than the other, but I've seen people run both with no issue. I'm keeping mine on the cold side because I feel it'd be too crowded on the hot side.

why do some people put the bov on the cold side and some put the bov on the hotside

Thats a good ?
Coldside = closer to the TB pressure released faster , holds boost better than hotside , leaving your pipes somewhat charged.

Hotside = releases out more hot air instead of cold air which the hotter the air more pressure loss your going to have which in the end is less power.

[PrimeDirective]

It is always better to have the BOV on the cold side, especially if you are going to recirculate the flow so that you will keep the air traveling in the same direction.

Someone correct me if I'm wrong but, I think people only put the BOV on the hot side for convenience.

[doitsidewayz]

ok cool, just wanted to make sure it wasnt needed before cutting it. thanks a lot guys!
and as far as my bov being on the hotside...my pipping came with the flange on that side so yeah lol

[SlideOrDie831]

hot or cold side, people don't care. you get less surge on the cold side or so they say.

[Prozac]

My piping (cxracing) puts on the hotside for the redtop , I am currently running the bov as recirculating , which means the bov is recirculating the hot air from the hotpipe back to the mid section of the air intake , which then is being mixed with the air coming in from the cone filter. Im thinking If I stay with the recirculated bov I would want the cooler air after intercooler mixing with the air intake. Makes more sense , keep that shit coool! Im going to make some perforated containers on the front of my intercooler and pack dry-ice in that shit , lol j/k.

Cold side here, same location the stock one is. (s14/15 at least)

[SlideOrDie831]

s14/s15 is on the cold pipe from the factory. s13 is on the sidemount IC.

[Hoffman5982]

I've been running my BOV off that pipe and I feel like it is less responsive than it would be with the flange welded directly on the pipe. We'll see when I get my cold pipe back.

OP- Have you ran the motor with that expansion plug in? If so, i'm assuming it has held? I will need to block mine off as well and I'm trying to figure out how I will go about doing it

[Tantwoforty]

I'm running 14 piping on my ka and i have that, expansion plug holds fine but you will need to replace it after like a year as it will start to crack and dry out
Not the best pic but you can see the nipple
14 piping fits pretty good on 13's and has a larger hot side than most 13 piping (larger for longer anyway, reduced right at the turbo instead of by the dizzy)
This is before i fixed the holes, it sits lower now

[Hoffman5982]

Well I got my cold pipe on and can say that the bov is way more responsive than with it coming off that pipe. No surge at all now. Shibby
