[benl1981]

Hi there,

Does anybody have a pic or link of the standard BOV config in an R33 RB25DET...

Showing the pipe it mounts to etc.

Thanks

Here you go, just took them for u now.

Cheers Chris - that was great you doing that.

I'm just trying to track down a stock setup. A guy in melbourne on these forums has the stock BOVs but not the piping...I'm wondering how hard that will be to get ...

Here you go, just took them for u now.

Where does the BOV channel the air back to - the standard Air filter box?

What are you meant to do if you have a Pod filter or simlar?

Can't quite see from above and this one below

Cheers

I have a POD filter on my car. Dont think it has any influence on the Blow off valve. The stock setup is just putting it on the stock pipe. Making sure the Plumb back pipe is connected and that the smaller pipe from the BOV to the Manifold is also connected. And it should be fine.

Seems like my car has the standard BOV still connected with all the hoses (doesn't appear to be tampered with)...plumbing back into just after the POD

How can this be. Do some people add a HKS while keeping the standard BOV there.

So I can just take the HKS BOV off?

Is the HKS doing most of the work?

Gee these are nice motors.

Where is the HKS bov located - please post a picture because it would be unusual for there to be two bov's installed.

Typically the HKS bov will be located where the standard bov came off.

[Edge]

It would make sense using both bov's though as a means of utilising the designed in 'leak' of the standard bov for the purposes of keeping the idle working correctly for the standard ECU.

The point I'm not sure about is whether the standard bov would have been screwed really tight to stop the valve from opening.

[krzysiu]

ive seen the pictures, the stock bov is not in the stock position.

[benl1981]

I'll get a better pic. Pretty tired now, will take it tommorrow.

So Edge, you can adjust the standard BOV. The standard BOV looks the same as in Kryz's pics...

Thanks

[benl1981]

Ohh - hi there Chris. It has the standard BOV aswell as the HKS - same as in your pics just with the HKS aswell in a different spot...

[krzysiu]

Hey Ben

is the HKS one welded onto the pipe?

[benl1981]

Yeah it is Chris. Will get the digi out tommorrow and have a better look - but traced all plumbing from the standard BOV and there seems to be nothing disconnected ....

Wonder if this means I can just get that pipe that has the HKS on it and replace it..

[krzysiu]

yeah i think replacing it would be the way to go, i dont think i would recommend cutting it off and blocking the pipe. Then after you take it off you can sell it along with the pipe

[benl1981]

Thanks Chris. Do you think my standard BOV will be still working - seems wierd both seem to be connected. Will post pics tomorrow.

[krzysiu]

Both can be connected. I got one friend with an R32 with a HKS one and a stock one connected. This is how it works for him. When he drives the car normally the stock BOV works normally and there isnt enough pressure to open the HKS one. When he full on floors it then the pressure is higher and then the HKS BOV vents the pressure. If everything is connected i dont see y it wouldnt work. look foward to the pics
