Fellas,

As the subject suggests... I got myself a nice HKS SSQV s2 (atmospheric) B.O.V a couple of weeks ago and my car's been stalling like a sick dog for no reason... the sound of the HKS isn't actually top-notch either so I've decided to go back to stock... as I don't want the car to keep stalling and the stock SSHHHHHH sound isn't too bad either...

Was wondering 2 things...

1) Anyone experience similiar issues with Atmo B.O.V's?

2) How do I make my stock B.O.V sound better which makes the nicer and louder sshhhhh sound?

Regards,

Just to save you the flame, have a quick search and you will find many topics about this.

Skylines dont like atmo venting BOVs.

Stick to stock. Theres nothing wrong with it. And if your only after the sound, well... thats another story.

Stock is fine up to a certain point, after that get a stock gtr one

a full plumb back (or atmo, its adjustable) GFB Stealth-Fx bov can be found for near-enough to the price as a gtr unit, if 3rd hand is good for you ;)

works great, bigger turbo holds boost better (was bleeding off too much), and it doesnt sound stupid in full plumb back mode, a little flutter of air reveberation between turbo and afm when you lift off the throttle

ecu with safc (tuned to previous bov) works fine with it

awaiting a hks actuator, so will retry stock bov but I feel that 16psi was a touch too much for it (dropped to 14psi all the time)

Thanks fellas... I guess, there's nothing wrong with going stock... besides, the POD has good stocking and let off sound so it's not too bad (sound wise)... as for the atmo one... man, bleeding and stalling like a biagge.... lol....

Anyone know how to modify the stock one a bit to make it sound better?

Search the DIY section but found nothing.

rev can you link me to the diy mod to make it hold boost?

"Crushing:

"Crushing" the BOV just means sticking the piece in a vice and pressing the top had down causing the internal spring to shorten and increase pressure on the BOV valve."

will try !! =D

Update: Installed the stock BOV on my car this morning... at first (maybe because the ECU) was still adjusting... it kept stalling... but then after an hour or so, it tuned itself and is running nicely now ... no more stalling... damn, spent a bit on the HKS SSQV and now back to stock... some times it's not worth modifying.... I'll let it run a couple more days before giving everyone a run down. Thanks.

Isn't there an attachment for the SSQV which allows it to be plumbed back?

Although stock is good, its also about 15 years old.

Plumbing back your new one might not be a bad idea... just my thoughts.

R31Nismoid, I he might of been referring to the ECU getting out of limp mode?

Stock ECU is a learning ECU right?

Edited by infamous_t

stock ecu is a learning ecu. if they are reset or things change they adjust accordingly in very minor increments. that would explain the time taken for the car to adjust to the bov change.

Err...no. Although it appears that does work for some people I don't know that I'd give that one a crack unless you had a few spare stock BOV's.

The mod involves little bit of a drilling, you should use a vice however to hold things while you drill though.

Someone did post the instructions up some time ago. Will go for a search for you.

my hks ssqv bov never made my car stall. aslong as you keep the standard bov plumback and set up a t-peice in the vac line it will run fine. if you only run a single vac line to the atmo it'll start stalling and what not.

My ssqv replaced the standard bov in the factory position and i don't have any problems using the single vacuum line.

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
