im a bit confused,

my car has 2 BOV's it has the stock one which goes back into the intake and i have a HKS SEQ as well? i have wound the boost up to 11.5psi, should i be removing the stock bov?

hey Ash

I have the same prob as u...they left my stockie on wen the put the HKS one on..

if u find out wat to do can u tell me plz :)

thanx man

SXCSKY i have the exact same setup as you! :) same place and all,

i don't know if u loose power, i think thats only if it leaks, but how do you find out?

Hey Ash...i dunno how to find out...im takin it to UAS 2day and see wat they say

Tell us if u find somethin out

cheers ;)

howdy... my skyline aint got a BOV.. but has a POD... anyways... i want a BOV on the beast and by what i have read... being a girl and all... a BOV basically could lengthen the life of ur turbo... any one object? or has reasons y i shouldn't invest in one??

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.

Thats cause gtr's have 2 turbos :D hehe

yer i've herd the bov mod works good.... ?

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....

hey guys

Ok nowim confused 1 dude says its ok to have a stockie BOV with ya BLITZ BOV ...and another says seal it....and another says just switch the vacuum hose over to the BLITZ BOV .....ok guys so wat should i do then .....????? plz someone tell me way to many opinions on this subject :headspin: ....oh yeh can someone help me with the reason y i get a small backfire wen after the BOV goes off????

thanx guys :D

as far as i can see i dont have one... but i have been tol i do but it dont make noise?! i dunno i new to skylines only had it for 10 months & still learning more everyday... if someone caould give me some more info on where to find to standard BOV that would help other than that i am lost... thanx for the tips guys... i am thinking NOT 2 worry about getting one. i just got my beast back after a cracked head & head gasket lol shit happens... damn trucks!

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....

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
