Hey fellas,

As most of us know, R33's stall as hell when there's a atmospheric installed - it plays with the airflow meter, mixtures and ecu settings etc which caused really bad stalling issues... I've put back my stock BOV, but I miss the nice pod-suction sound heaps and also the Sshhhhttt sound - driving a turbo without this sound really is a bit of a let-down.

I've heard though, if I get a BOV which has 2 sides - one that plumbs back and the other that vents out - I'll still satisfy the requirements of the car and will also get the nice blow-off sound.

Which ones would do the above - any suggestions, fellas?

Thanks in advance.

GFB Hybrid bov does exactly what you asked for.

I've got one, but ive got mine plumbed back entirely. I dont like the pssshht lol. I used to have it 50/50 plumbed and atmo. The car stalled a few times over months it was like this, usually under hard braking.

I love the pppssshhhhtttt sound. lol

I hate it when the car stalls if full atmo, so I'll go 50/50 then... yeah, was also thinking of the GFB Stealth FX BOV... sounds nice and also heard some times it doesn't stall on R33's... what can you do though.. ha ha ha

Thanks.

I wonder why everyone's going back to stock - is there a reason for this?

Just keep the stock man, you can't go wrong!

I used a SSQ for like 10 minutes, then blocked the stock BOV off..

1 week later and I unblocked it all and had it running normal.. you don't realize how smooth and nice it runs with the stock plumb back setup until you change it :P

The stalling, lag between gears, its just annoying.

My opinion anyways.

Wow, thanks for the heads up mate... but I love the Ssshhhtttt sound... damn it... really love that sound... but I know what you mean buddy.... I know perfectly what you're referring to... stock does make the car run much smoother - not to mention no more stalling which is a pain in the arse... thanks mate...

If done right, would the GFB work just as well if no lag?

Cheers,

any bov will not stall if you tighten it up a lot. my line was imported with hks ssqv and never stalled. about 6 months in everyone i knew was getting pulled over so i changed to an r34 gtt bov, which is the same as a gtst, and can still hear turbo noises to make me love driving the car, but dont have to worry about getting into trouble lol. its a stupid thing to be defected for, especially when the original equipment is so good

i guess if you really like the sound then in the end its your call. i drove a rex with one and after a day of driving i was over the sound..ha. negatives outweigh the positives in my books so i stuck with the stocker. i still get the pshh sound with my arc box, just not as loud though.

i was wondering if u do get something like gfb stealth fx and tune it for full atmo

and sometimes you decide to adjust it so its full plumbback how this would affect the car?

if u did this, when the car was running a full plumb back when its tuned for atmo, ud be running your engine really lean and could cause engine damage.

And how exactly do you tune a car with an AFM to run an atmo BOV?

with an safc, the DecAir settings. on a full aftermakert ecu with a deceleration enrichment/enleanment correction map (what its called can vary from ecu to ecu).

Yeah I know what you mean... is the 'original' stuff that good? sounds good... I gotta say, the stock one doesn't stall is that's a first...

But I really miss the nice tough suction sound and the ssshhhtttt let off sound.... how the heck can I modify the original to give off more sound whilst not stalling the damn car? :)

I heard blocking the hole spools up faster but will crash the car.

the only reason ur car stalls wen its at full atmo is because u havnt tuned it to have a fulla tmo BOV. i run a atmo bov all day every day and it never stalls ever.

I'm going to install a emanage - do you think the BOV can be tuned to work fine without no more stalling?

Thanks.

^^ Nah he's serious, have a read of his other threads. *shakes head*

Thien, you cant get the sound of venting to atmosphere without the problems that come along with it, unless you change over to an ecu that does not use an AFM.

ive had no probs with my vta hks ssq.

stock ecu and management.

it actually has increased response.

lol and for some reason i gained 0.3hp (yay).

so apart from the pssscchhhhttt sound man. there is no real benefit of going vta. just means when u accellerate u get that at times unwanted effect and the attention that comes with it.

im sure there has to be atleast 1 1000hp+ car out there that runs a plumb back bov... surely?

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
