  • Hks bov with fins ftw..

  • yay for pussy revs on a rip off SSQV

  • @SuperSuprastar i plan on building one one day too :D

  • 45 people drive a lamborghini murcelago

  • too many supra videos.. when i first watched this even though it says nissan skyline i thought there was something wrong with the camera because the intake manifold is on the oposite side from supra engine.. thats just how they're made.. brainfart!

  • thats an rb25det my mate had an r33 with one and it was some car

  • what brand of bov is this?

  • @iXMAJORXi i think it's HKS

  • @iXMAJORXi HKS SQV most popular in my country malaysia sound like blades...kechingggggg~ =)

  • dumb bogan cunts get a real job

  • RB20DET

  • @Glockmagic2 sr20det not rb and this is a rb25det

  • @marcky89869 there is such thing as an rb20det.... in the base skylines

  • do i need to have a turbo to install a blow off valve?

  • @poncecarra

    yes or supercharger!!!

  • @rjpr33 superchargers dont need them because they are belt driven, ie, no way will it spin the other way.

  • @poncecarra Yes. A motor whitout a turbo just have vacuum in the manifoil. no pressure that drives the blow off valve. Whit a turbo you got pressure in the manifoil. And that opens that valve, who opens up so the extra pressure goes out

  • @poncecarra : is this a serious question?.....O_o

  • @Greddy305 I KNOW IT SOUND'S KIND OF STUPID, BUT FOR REAL I'M SERIOUS!!!! BUT, THANK YOU FOR YOUR ANWSER!!!

  • @poncecarra LMFAO!

  • RB POWER YEHHHHHH

  • Nice sound broo..

    but why sell it on ebay?

  • some one reply is that all stock except for the turbo and blow off?

  • @242DEE It looks like it stockish.. cooler + exhaust and bov

  • hey pussy give it more power ! you can't hear the turbo or the blow off suond good!!

  • have u sold it?

  • nice sound.but u cant beat the turbosmart mega sonic bov it sounds like a jet taking off.

  • SICK

  • now that!!! it what a blow off valve is supose to sound like

  • i miss my rb25 yours is a series one also i had mine in a s13 coupe

  • That looks to be a HKS SSQV. I have the same, but on a '92 VR4. I can't seem to get it that loud.

    Then again; i'm on factory boost. Ideas?

  • could also just be the vid

  • i have a 92 talon tsi, and i had a stock exhaust on it for a while with a 20g turbo at 12psi, and the bov is a greddy type r, or rs (not sure exactly) and then after i put a 3" turbo back exhaust on it the boost went to 18psi without even touching the boost controller and the BOV sounded ammmazing after that... so try changing your exhaust, it really makes a world of difference in turbo cars.

  • (plus... the hoods open, and the camera is right next to the bov, its not half as loud when ur driving wit the hood down.)

  • if you look close, his recirculating hose is off. not a good idea beacuse it will run funky if you just take it off

  • gotta love the synapse

  • it wouldve been better if the hks sound would last longer though its just a quick whistle and its done

  • what kinda blow off valve???

  • that one would be a HKS

  • let me guess you drive a fire chicken?

  • I see you are still running the airflow meter without running the plumb back, But if a puff of black smoke on a gear change is what does it for ya.

  • you dont know what your talking about mate.... You dont need to plumb it back when running the afm putting it in the atmo is fine. Notice the stock j-pipe with the bov on it? A simple upgrade of removing stock bov and replacing.

  • What the hell does the stock pipe have to do with it? Or the type of valve. The point Im making is the rich spike you get on a gear change when on boost, caused by the BOV being vented to atmo.

    I will go into more detail if you wish.

  • go on....i want to hear what u have to say....

  • The reason is, when you shift & the throttle body closes & the valve opens the air should be returned to the intale after the AFM effectively closing the AFM therefore reading little air flow resulting in a reduction in fuel flow. if done atmo the AFM will continue to read that X amount of air is flowing through the intake and fuel accordingly resulting in the spike. We've all seen a skyline at some point chuck a puff of black smoke on G/change this is why.

  • ok cool

  • no worries glad to be ifnformative

  • Yeah I do to mate. The reason I referred to the stock bov and j-pipe is because your claiming that the bov should be plumped back when running an afm, when the c33 laurel's a31 cefiro's, and the skylines come stock putting it into the atmosphere. There is no spike in fuel when you change the gear ONLY if your a shit enough driver to have your foot on the accelerator as you drop the clutch and change gears. It is not caused by the bov being vented into the atmosphere there are mainly 2 reasons...

  • number 1 reasons is that due to the laws such as in Aussie *quote me if I'm wrong someone* the land transport see's the air going into the atmosphere a pollution *We all know that's bs* just as they see screamer pipes.

    number 2 is due to some people seeing it getting plumped back more gain through the intake.

    These are the only reasons. If you have/believe a 3rd reasons which I believe you do you should share it with us so please go ahead and go into as MUCH detail as you can. Cheers

  • Take a look below my explanation is there.

    I must say that the BOV being vented to atmo on skylines is a new one to me.

    Many change the valve to atmo without knowing the effects (apart from sound) both positive and negative.

    There IS a pollution aspect being crank case gases which would be returned to the intake and being burnt. Unfortunately oil mist is a effective octane reducer, not good. Its more about the noise just like the screamer which relates to exhaust & the cat.

  • Yeap they did vent the BOV to the atmo in many early model skylines. how is there is a pollution aspect when all it is is traped air in the intercooler piping? It doesnt go through any oil or fumes unless the turbo has a leak. Why did you mention the cat? The cat just filters stuff?

  • The crank case breather vents into the intake prior to the turbo so any atmo venting releases these fumes. Minimal amounts but it is there. (you'd be suprised how much oil coats the inside of the I/cooler if you don't have a catch can)

    The cat is not a filter but a catalytic converter provides an environment for a chemical reaction wherein toxic combustion by-products are converted to less-toxic substances.

    There are two main types but I won't go into that now.

  • less toxic for the environment. Details are not needed thats a whole different subject. Its best just to gut the cat lol due to becoming ineffective over years of abuse.. Whats your take on front facing plenums?

  • I'm assuming you are referring to the plenum on an RB25.

    It's not a majorly effective upgrade unless you are chasing big power, looks, a shorter inlet path etc. The factory plenum can made some really good numbers.

    As for the cat I decided to get a high quality high flow than risk the 5K fine.

    Having a tweeked up rotor the cops will sooner or later give it a once over.

    Had no loss in power or sound.

    A good 2nd hand gtr cat can flow heaps for a good price and still be legal.

  • well you got aftermarket ones for any rb here we call it chop and block and its simple as that...chop it and block it and put the throttle etc at the front lol. Exactly and it gives better throttle feel. Hmm 5g fine? shit where do you live? here they would do nothing and just make u get a new one. I got a nissan c33 laurel wich is rb20 but i got s2 rb25de which im going to +T for higher comp with a rb20det gearbox etc etc. should be fun. Whats your rotar?

  • Got a S4 fc rx7. 13b turbo obviously.

    Had it built by Rotormaster bout 1 1/2 yrs ago. but havent been able to register due to a fuck up by the fools who complianced it and made a mistake. Now Im about a month away from getting the second compliance plate back.

    Nearly lost the thing in a flood where it is stored two weeks ago. And thats 300km away so was freakin but got a truck in.

    That engine cost me  5 1/2 thou.

  • Wow I have to admit I didnt know what you where on about but now I do. Yes what you said is exactly what happens as the 'crank case' which I more commonly call it the rocker covers gains ALOT of fumes and moisture which gunks it all up and this does need to be released so they put an outtake to the bov to release it *yes it is very little* thus acting as a catch can *catch can is better of course* and yes a cat also known as a catalytic converter provides a chemical reaction making the chemicals

  • Listern Bruv Only 2 words To Say 2 U "No Taste" ;)

  • man gas that shit i wanna hear that shit lol

  • 33?

  • cool!

  • wat kind blow off valve/? is it hks?

  • blitz

  • nice ;)

  • i've always wanted a skyline! dick

  • tuff guy

  • how the fuck u sell a car on ebay....... only a dumbass wud buy a car over the internet an not inspect it.... wow ppl never seem to amaze me...

  • haha they obviousli inspect it u think ther gonna deliver a fucking car to ur door step

  • you bid for the car and if you have won the bid you go to the owners house and you check the car and buy it. (YOU CAN ALSO CHECK THE CAR BEFORE BIDDING TO MAKE SURE IT'S IN GOOD CONDITION AND EVERYTHING IS OK)

  • lol u haalf to out bid just to go look at it...wdf is the point of even using ebay...just go look at it an if u like it buy it.... fail on the owners part for tryin to use ebay as a car ad company...

  • yeah your comment lacks intelligence Weewoodeal. I've bought plenty of vehicles off ebay and i always inspect them first. :P

  • lol how r u goin to inspect the car ...i doubt its in the same city as u ..... fuckin retarded....just go an look at the car,,,,theres no ponit in even using ebay to buy it...dont lie lol ;)

  • u must b retarded u can always put the amount of miles away u want 2 find a car smart guy dont talk about shit u dont kno makes ur self look dumb

  • of course it blows ;D,its skyline! :D

  • Thats a 2.5 GTS-T skyline

  • U have to bolt on a underbody spoiler package to really get over the 200mph mark, but after that it's really not anything guesswork, just balls and pushing it, I havn't clocked it on track slower than any car, but I still have ton's of power untapped, I also have her clocked in the 2 mile straight at 267mph with a faulty blow off valve.

  • You are talking absolute shit.

    Are you actually having a laugh or what?

  • haha i bet so..

  • I have done all the work myself, and I put no less than 45,000 of parts into the car, alot of custom chassis parts, and lot's of abnormal Mustang upgrades. The only difficult part I have about handling is my rear axle, which is a Watt's link 9 inch rear end, does pretty good, and I out handle enough that what I can't out turn I easily over power in the reacceleration phase of the turn.

    I'm the Mustang guy I light my rears up I leave a pile of rubber in just 10secs bigger than your hands

  • well, stangs are good in drag, can they keep up with a circuit with an r34..?

  • @aendzo The old school fox body 5.0's could keep up with the R31GTR Silhuette back then.

  • @aendzo can they keep up with a skyline in any kind of race

  • @aendzo That isn't an R34, nor is it a GTR.

  • GTS Skyline's are a joke, i agree, but if you were to race a GTR Skyline, man you'd get blown outta the fucking water. quit trying to brag and sound cool. nobody fucking cares about your fucking mustang.

  • GTS skylines are still bad ass you can do the same shit to it as you can a gtr your just going to have alot of tire spin

  • I have to disagree, buying a gts is like buying an automatic, 4cyl, manual everything, convertible mustang compared to buying the top of the line one. GTRs have so many other advantages, engine size, braking, suspension, ecu, etc etc the gtr was designed for racing (the wider rear curvy quarter panels are for side force) the gts is the cheaper model.

  • But the gts is not all wheel drive like the gtr so depending on what you want to do with it is a factor you have to consider. now as for engine they are 6 cylinders and everything with a max of a .6 liter difference Id take a gtst over the gtr any day due to the rear wheel drive feature and endless tuning possibility like the gtr.

  • I agree there the only way youd want gtst is because of rear wheel drive, After owning a gtr and driving a friends gtst I just felt no comparison between the two power wise, Gtst would need lots of mods before Id go for it. But yes it does depend.

  • You are correct there the gtst would take quite a bit of tuning to get it to the power level of a gtr but it really is quite pointless because of the rear wheel drive. But either way you go you cant go wrong really all skylines are awesome :D

  • Strelitz50, we all know your lieing, mustangs are total garbage trust me

  • car wasnt great but the sonund wasnt eather

  • lol i mean what brand/type :D

  • it all depends on what kind of mustang... if you're talking about a GT than you're one of those idiots that think it's fast... if you're talking about an 03-04 cobras than i'll give you that

  • skyline GTS-T no gtr

  • whats the bov?

  • blow off valve BOV

  • it looks like a HKS SuperSequential BOV. i used to have one on my old s13, doesnt sound pretty like a flutter valve but actually does the job its meant to do.

  • that's an RB25DET. nice BOV by the way!

  • that sounds crap.. aint even worth putting on

  • nice

  • is that an r32 correct me if im wrong

  • thats not even the dett series motor...

  • cuz its not a gt-r...

  • lucky lil bitch

  • mite wanna update the description

  • Your ebay link is broken.

  • yer your right tjessop20 not a proper liner (GTR)

  • tjessop20 your a twat! that is all i have to say!

  • jus blok dat bigger blak pipe runnin out da otherside of ur bov(which leads to ur pod) n den ull get flutter at qtr boost but strait ppssshh at full boost..;)

  • like it alot m8 :)

  • rb25det so sweeeeeeeeeet

  • lol

  • it doesnt matter >.>

  • wtf are you talking about ?

  • sure, whenever you shift the gear with the automatic, the valve blows off air XD

  • lol yea

    idiot

  • wow i feel sorry 4 u that is by far the stupidist shit ive ever read.

  • yea you can and its more useful than ppl think. every time the pedal is dropped quickly it will blow. its a stress reliever for turbos. it releases compressor surge when the throttle slams shut. mainly for ball bearing turbos due to inertia but are used in others. a cbv is preferable for autos

  • wow in the first vie i knew it was a rb20 to rb26

  • lol rev that shit up

  • does it matter if you buy a no name blow off valve?

  • Hey i have a BOV on my 1.8 turbo but i can only get the BOV sound when im switching gears or if i have boost goin and let off the gas.... how do you get the blow off to go off when you are in neutral or not moving... let me know thanks... NICE SOUND

  • just rev the car..

  • a 5G rpm release

    =]

  • wow, do u really not know how to rev the car from under the hood? u just find and pull on the throttle from under the hood. he was doing the same u do in ur car (rev it up then let off) he just not behind the wheel.

  • depends wot car ya got, i've got an audi 1.8t with a forge splitter valve on it. if i set the valve up 4 atmospheric, it still doesnt make the noise cause i've got the AUM engine.

  • wow it sound really sharp...

  • if i did work on my car id never show people whats under the hood...

  • yeh i got a 34 non turbo, waiting for DET swap out and rebuild, haha for the time being, my gf makes the blow of sound while i drive rofl...now that a custom blower ;)

  • sweet bov man!

  • i put my head out the window and blow a gym whistle everytime i shift..bwahaha

  • ricer

  • haha what makes me a ricer? the fact that i made joke..whatever dude your the ricer fag

  • nah the fact that u try to make it seem as if you have one makes u a ricer. u should probly look into gettin a turbo whistle so u can brag some more

  • Tuner man tuner

  • not a real one i dnt think

  • lol, of course no. technically you can but it wont do anything at all.

  • ahh.... so even if it doesnt do anything, it will still make the 'blow off' noise??

  • no, the valve open when the throttle body closes and the pressure has nowhere to go but out through the blow off.

  • u can have a fake BOV sound setup. i saw it on the internet the other day fr like 500 bucks. it times the sound with then engine so it sounds realistic... but it will not do shit. and ppl will call u ricer.

  • I think you can. Just stick your head out the window of your car and when you change gear just make a loud whoosh sound!!!

  • lol owned!

  • No. You have to have a turbocharger because of the boost that runs through the hose lines and through the intake. The blow off valve just releases the boost and then recirculates it to give it that whoosh sound.

  • ah! thanx.

    thats wot i wanted to know..

    cheers!

  • Yes you can put one on, the gate wont open to allow the pressure to be released cause theres no pressure lol....so can open your hood and show everyone you have one, but when you drive and they ask why isnt it doing anything i guess you have to say its blocked or somethin haha.... :P I heard of fake ones, they put em on FWD's and weird ass cars that should never see the light of forced induction, thats as close as youd get, why you'd get one is beyond me...

  • NICE! :D

  • that sound on BOV is tha best

  • nice sound!

  • What? You mean what turbo they use??? IDk but its a HKS Blow off valve and thats why they sound so nice

  • you could get that sound on the skylines stock bov but youd have to be running higher rpm, that is with stock boost pressure..though you could pretty much put a Bov on any turbo car, any psi the only diffrence is its sound and when it releases.

  • Stock?

  • that noise can be made with a stock BOV with just a good quailty air filter. As i have running on my r33.

  • motor sounds tight, so does BOV

  • 400 bhp on a GTSt is about 1.2-1.3 bar on a t3/t4 sized turbo

    the standard recirc is fine, upto this point many of the aftermarket no recirc blow off valves cause severe idling and running problems,

    TBH if your going to run big horse power an external gate would be better and negate the need for a blow off valve in the first place,

  • It is good♪^^

  • i love how pissed off the motor sounds.. sick =)

  • IT'S r 33

  • the std recirc is good for 400 bhp ;)

    the aftermarket ones can cause stalling, it depends on the car really, some stall... some don't... I personally prefur the recirc sound into my hks filter, but it's cool either way :)

  • uh... it has nothing to do with the power the motor is making. It has to do with the PSI that the turbo is making (depending on the turbo you will make different power at different psi, thus power is simply an irrelevant variable). I wouldn't trust any "stock dump valve" from nissan past 10 psi if you want to avoid boost leak. SSQ's are great for higher psi but tend to keep closed if under 12 or 11.

  • rb25

    jealous :D

    wanna trade for my rb20

    bahaha

    props for recirc btw, i just cant bring myself to do it. i prefer stalling out in parking lots :D

  • you only stall out if you set it incorrectly lol...

  • hahahha...

    dude no

    no matter nicley you set it..

    theres still a whole bunch of air leaking out that your ecu doesent know about.

  • that bov is recirculated, whether its stock or not idk, but its definitely recirculated

  • If we are talking near stock the R33 will smash the R31. The RB25 out powered & torqued the RB20. Or are you talking about the FJ20. Still, the result would be the same.

    R32 was the car that changed Nissan's image for ever. Dont get me wrong, R31 wasn't a bad car but it was no R32 or R33.

  • Non return BOV on an A/F//Meter equippped RB25, Money spent for sound only, sounds good but don't need the puff of soot out exhaust on changes. Doesn't do much for economy either. The factory plumbed back for a reason other than noise.

  • my m8 had an R31.. SOCH 2L turbo manual.. i know that R31's came out in 2L's and 3L's.. so unless ur R31 is 3L turbo then this would rape u!

  • mavis1234 lol i guess everybody has a fast car.... on the internet lol

  • this car is pretty much stock so dont talk shit
