I don't understand how you can have the stock bov in the same location without it functioning?

very simple, instead of having the standard gasket under the stock bov, u replace it with a coke cak gasket. u may ask what a coke can gasket is? this is a gasket that doesnt have a hole in it but is still the same as standard thus sealing the hole into the cooler pipe that normally would be there (u use a coke can to make the gasket), and then with the vaccum line, all u do is tape up the nipple under the hose and put the hose back on.

with this done there is no vaccum and no pressure on the bov spring thus eliminating the stock bov from operating and just being a dummy bov.

How about you just use the stock one?

Mine is still there; and I have a GT3076 pushing 18psi - 20psi and 300rwkw.

Doesn't bat an eyelid, and the cops don't care because they can't hear the engine wanking itself under the bonnet.

How about he does what he wants?

I have a atmo bov, have had for over 6 years. i like the sound of it even if it makes my car stall occasionally.

I could care less about chics or the crap u tell urself guys fit them for. Ive never had a problem with the cops, when they are around i know how to drive and dont boost it. not that hard really.

each to their own mate, let it go.

rofl

I'd go crazy if my car did that stupid shit all the time.

I had a atmo once, tried it to see if the standard one was leaking, and my car stalled and ran like a piece of shit when off the throttle. Couldn't get it off the car quick enough.

heh yeah if it was all the time i would get rid of it, but its less often than rain so yeah for me the pro outweigh the cons.

i have my stock one still here i have been thinking of refitting as tho i do like the sound its much of a muchness really.

anyways im off to pick up my 26 head the baron so kindly sent me

ps. from the sounds of ur atmo experiences something wasnt right, maybe ur installation or quality of bov.

Hey Mafia,

Since you have mentioned several times that you are using the stock bov with your 300+rwkw car...I have a proper technical question for you...pushing that much air through it all...what size of plumback piping are you using? still the standard diameter and hose that came with the car?

still using the standard return hose. We just modified the end that hooks up to the intake pipe, and welded a small pipe into the 4 inch intake pipe to suit. So the stock return pipe is exactly the same.

Works 100%. I don't get any flutter or fully sic dose.

The Pipe is more than enough to drop the pressure so the turbo doesn't surge.

You can still hear a little bit of blow off through the pod, but barely at all. I will one day make a decent airbox so its completely silent.

Why can't you just let him do whatever he wants?? eg.I don't like your rims on your '300kw' car..., but i dont go making a point of it. People can do wahetever they want to thier car, you dont always need to critique them.

I'm thinking of changing them actually.

But at least they don't go "WWWOWOOOOOOSSHHHH, HEY COPS, COME AND BOOK ME AND HASSLE ALL SKYLINE DRIVERS"

yeh i no, but everyone will realise in there own time what they do and don't like, I had atmo once, got sick of it.

Yeah I get it. So it doesn't have to be substantially thick? Do you also need to block off the pipe that plumbs back?

You wouldn't need to block off the plumb back line if you already have blocked off the actual bov with a solid gasket. Wouldnt' make any difference, no air is able to go through it anyway.

Mafia is it reliable at 20psi i.e. no boost leak? i was thinking about this the other day

atmo bov's give us all a bad name and generally reduce overall performance i.e. dumped air is usually 'lost' (not metered by ecu) causing running/stalling issues.

just use the stock one that actually works well i.e. plumbed into compressor side

As i understand it your problem is the cops don t like you BOV going atmo so you have a fake/blocked BOV in the original spot and your new atmo one hidden under your guard. Most people wouldn t worry about ATMO BOV noises, is the PFFFT noise really an essential part of cruising round. Im sure the marketing people employed by the BOV manufacturers would like you to think it is.

Mate, everyone likes to have a car that stands out and expresses thier own individuality but sometimes you have to look at the facts and wonder is it worth being hassled by cops and sacrificing drivability for little or no reward. You could probably win the tour de france on a tricycle too if you try hard enough.

PS i have owned and driven both aftermarket and standard BOV set ups and i currently use standard nissan one as there is no need to change it.

wow this topic caused quite a stir lol. the only quesiton i have about this topic is, why the fu*K is it illeagal to have a atmo bov. i mean really, what harm does a bit of air make, and if some dick cheese gets scared of the sound and crashes, they shouldnt be on the road in the first place! i just bot a turbo'ed patrol as my second car and it has a atmo bov, within 2 weeks i have to go to epa, its not worth the trouble so im going to take it off, i just wish ppl didnt care about that sort of stuff so much! thats my opinion, like it or hate it i dont care.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
