u dont want Atmo bov and plumbback. coz the plumbback is known to leak over certain boost levels which will lose u boost. thats one of the reasons u upgrade to HKS or watever. as far as pressure goes, it wont make much difference since its just doubling the release of air which is good. some going back in will act like them hybrid bovs too stopping it stalling or watever coz it stil lgets air back to the AFM. but it will make the HKS quieter too probably coz not as much air coming out of it.

id remove the original i reckon. just block up the places where it goes in i.e. put blockers up any pipes that are left from it's removal. easy.

no need for 2! or yeh u could also just jam it shut somehow but easier to take it off and fill the holes with something and clamp it up nice n tight. :)

R33NismoGirl - Your car has a blow off valve standard. Has it been removed?

Ash - there is nothing really wrong with having 2 BOVs. (GTRs have 2). The factory one would have been left in place to help with maintaining the factory idle characteristics. The 2 valves will flow much better than 1 and will therefore work more effectively.

Cameron & Ash - There is a thread on these forums about modifying the stock BOV that you may find interesting.

Well I am going to disagree with a few people here then...

recently I installed a pod, K&N tapered with chrome end...have had it for about as long as they have made this model (used to be on one of my dads many drag engines) anyway it sounds awesome, good suction noise and scares the bejesus out of the od commo driver...

You CAN hear the standard bov, and it is working fine, however I have replaced the standard BOV with a GFB stealth and all I can say is giddy up...

At full plumb back it seems to hold and come on boost quicker, I am aiming to dyno to prove my point unless someone beats me to it, has already been proven on a s15...

add to this at FULL atmo the car STILL idles like factory no backfiring, no hiccups nothing, its all a matter of a bit of spring adjustment. This is only factory boost (9psi??) and I am very happy...espcially after I replaced the BOV gasket with a new one as the old one created a high pitched squel which was in fact a boost leak....

If you have a stock airbox you won't hear the stock BOV...

i havn't got a pic to post but if you look at the pipe where the air inlet connnects to the intake manifold (near the firewall)... you'll see the stock bov with a black rubber hose coming off it.... sorry, i'm not very good at explaining but if someone can post a pic that'll show you where it is....

      R32 goes out in right curves

      That's true. However, this problem has started since the tuning. First time with the return journey from the tuning. But yes, the pipe was clogged with dirt and rust. That was certainly due to age

      Great info @tidi0x  Will definitely be handy for others and maybe me if I decide to keep the shit box H pattern.

      Bumping this up one last time.... I wanted to follow up on the clutch slave issue. I realized that what the issue comes down to is the pocket is flat milled, and the cylinder does not want rest flat. So in order to mount it correctly you will need to make a spacer for the fingers so the cylinder is floating. I took two plates of aluminum, drilled some holes and was good. I did still need to make the relief cuts in the bell housing, as even with the spacer the bleed section still interferes. The OE bell housing the mounting holes are raised from the housing.

      R32 Gtst - Track Car

      If the event in USA goes ahead will be interesting as it seems the rules will get more cars over here. Apparently the track is laguna seca too. Yeah s15, if I get a the lower dash trims, centre console and change front cross member to standard LCA position will fit clubsprint. See how rules are as i would rather do complete widebody than a bolt on flare to run the 295 with proper clearance.

      If the car is legal height I can't see it being an issue. Found a thread on reddit that might offer some insight.   I got a ticket from a copper in QLD for my S15 being too low. They had this wheel thing on a stick that they put under the car and it hit my exhaust. Anyhow went to an exhaust shop to get the exhaust tucked up/hung a little higher and I wound the coilovers up a smidge. Don't think I even had to go back to the police station unlike when I got defected for having a carbon bonnet when I brought the S15 from the ACT to QLD and had to replace it and then rock up at a police station and have a yougish female officer who knew nothing about cars confirm that I had changed bonnets. Should have just painted the carbon bonnet yellow to match the rest of the car lol
