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....

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
