R33 Stock B.o.v - The Best For The Car?

[Spunky Munky]

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.

Also, the stock BOV can be modded as needed. My mechanic does it for ~$100.

yea mate i get the same problem.i gotta turbosmart v port on mine.mind y my engine is f*ked now.but b4 that it had been stalling n still does.maybe get a plum back 1 or stik to stock

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.

The stock BOV is very good. Modification to it costs less that an aftermarket one, basically free if you DIY. On a stcok turbo there is absolutely no performance point to the excersise, unless you like 'pa-chooo' sounds.

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.

The ECU Tuned itself?

Thats new

[infamous_t]

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?

[cheez]

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.

Hahaha classic Spunky Munky thread

Mass fail involved

[frozenwaffles]

you could always get the plumb back for the ssqv

Hahahaha! He reminds me of one of my friends lol. Maybe he is him....

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.

Guess everyones car is different. I got the 2007 HKS ssqv and my car has not stalled once and also doesnt back fire or anything :|

[dmr]

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.
