300ZX Twin Turbo: Engine-Blow Offs N Turbos

[CalikingZX]

185 dislikes how is that possible!?

[ambee514]

I love the sound of a Blow off valve

[THEJDMLIFE]

Only the 2+2 version didnt come turbo......... in the u.s atleast

[sillyboy10]

@THEJDMLIFE yeah i have a twin turbo 2+2, but its a jap import ;) fantastic performance, terrible MPG...

[d240786]

Where are the BOV's They usually end up sat either side of the fan on these?

[Blessedtouch]

@d240786 probably in the stock location in front of the radiator under the nose panel.

[d240786]

@Blessedtouch Stock location?

Ive never known of a 300ZX with bov's fitted stock?

[Blessedtouch]

@d240786 well then you don't know 300zx twin turbos. Nissan probably calls them recirculation valves, because they divert the pressured air back into the piping before the turbo.

[d240786]

@Blessedtouch They aren't BOV's though they are called recircilation valves not Blow off valve's they are in place just to ease pressure not release it, you can remove them fit bov's or you can leave them where they are supposed to be and install bov's for thier own purpose, having both is more efficient, removing them will put extra strain on the turbo system.They didn't put them there for show and they didn't call them Blow Off Valves!

[d240786]

@Blessedtouch Dont act like a smartass when somebody asks a question that wasn't directed at you!

Recircilation valves simply stabalise vacuum pressure, not release it to avoid stalling, they shouldn't be removed and replaced with BOV's they SHOULD be used in conjuction WITH your BOV's and they should'nt be too close together either.

I know what I'm talking about so don't tell me how many friends of your's have done it or how many 300's you have sent to the scrapper!!!

[Blessedtouch]

@d240786 this is the internet if you can't handle responses don't read 'em. For example...I never even heard of anyone running blow off valves and the stock recirculation valves. Once you run more boost than the stock recircs can hold, they leak/fail. and having another set of pressure relief won't do shit.

"They didn't put them there for show " neither this car, or in stock form can you see them with out removing panels. obviously not for show.

[panterashaun]

meh jap crap bottom end will soon give out.

[Branden1119]

@panterashaun dude japanese cars tend to last twice as long as american cars, plus all america does with there cars is put a big dumbass V-8 in their sport cars... why not get a little more creative? weve been using the same technology in our cars since the 70's mucle cars; which were whack for real the compression ratio's made those cars run like shit... pooches

[jfkyz125]

@panterashaun hahaah what a dumbass forged crank forged rods and aluminum pistons stock your a dumb fucker i suppose you think nissan built and designed the vg30dett nope wrong again dumbass it was desinged and built for nissan they didnt have anything to do with it mechanically

[Teh1337Pirate]

That engine is beautiful

[SHAUNSPICERCPU]

TWO BLOW OFF VALVES (waste gates). One for each turbo. How is that wrong? Sweet car.

[teamEP789]

@SHAUNSPICERCPU you should look up what wastegates are mate...

[skilkiller10]

lol the title wrong i tink is (blow off valve n turbos) read the description he just wan to show off the engine but not going to blown it

[dethpig420]

Is it me, or does this video seem old? Looks to be a very old video considering how amazing that engine bay looks. Plus the film quality just has the funny fuzzyness to it.

[KIDzinGuyana]

thats not stock rite

[kevinonstenk]

me dad used to have one but it was an american version with no turbo but with 350 horsepower but he sold it. he now have's one 2002 Porsche 911 Carerra(996) but the 300zx was nicer...

[jdubcbr600]

300ZX twin turbos were as fast as the early 1990's 5.0 Mustangs so stock they arent as fast as you think a twin turbo car would be. Dont get me wrong, aftermarket turbos and some engine work made these beast but stock they were shit. Were talkin 9's in the 1/8 mile if that says anything.

[Branden1119]

@jdubcbr600 ... Thats the 80's Z

ZX TT run a 14 in the quarter mile

5.0 runs a 15

Corvette runs a 14.3

this is also 1990 when we were coming out of the 80's shit cars where they were underpowered peices of shit but i just researched the 5.0 and it is pretty close a second off but still decent

[GUMMYBEAYUH]

I still have my Old Man's 1987 300ZX sitting in the driveway right now. It's the car I grew up with, and it's the reason why I love Nissan sportscars. Z = An amazing machine, and a classic ride.

[420witchdoctor]

Sounds fucking dope.

[BrEnNo1023]

you take care of that baby, okay? that is one holy awesome car. Don't you hurt her XD

[weewoodeal]

you need to check your spelling because i have no clue what the fuck you are talking about

[tom9665]

2bad engine sounds like a coffee grinder

[johnwygant]

thats one badass coffee grinder.

[miamipacheco]

u can get them cheap nowadays, real nice car

[NissanTy]

nice sounding engine, seems like the vg30dett and the 300zx itself has been forgotten about the tuner crowd, few minor bolt ons and them things can produce 350-400 rwhp, vg was a turbo lover. vq engines are good but don't like boost like these old iron blocked vg engines.

[R350zz33]

@NissanTy the new HR series vq's love boost especial the 07-09 350z's the intake plenum was designed similar to the gtr as a test and these cars in na form with you basic bolt ons can make 320 at the wheels just with intake test pipes and exhaust and tune throw on some headers cams and thats almost 350whp

[xxFairladyZxx]

@NissanTy I agree the vq is for n/a, which they do fine.....the vg is made for turbo, and I think its a shame these Z32s are relatively forgotten about & ignored

[scootbmx01]

sounds pretty cool

[HARDSTYLENNO]

Nice Engine Is Everything Stock In That

[shamanmann001]

How the hell would that be stock at all???

[HARDSTYLENNO]

nissan did make a twin turbo version of the 300zx

[d240786]

@HARDSTYLENNO Actually they bought one!

[iTzMarky]

300z tt is twin turbos. from the looks of it it could be stock minus the dump valves.

[CJDaTman]

you can hear the bov's and you ask if it's stock?

[HARDSTYLENNO]

hey i asked ifit was i didnt say it is

[CJDaTman]

you can have a 300zx tt (twin turbo) bone stock. stock just means no after market parts are on the car. same case with a 300zx n/a (naturally aspired). in this car, it has plenty of after market parts, which means it is not stock

[FrenchClassIsBoring]

That sound is also produced due to compressor surge, not just by blow-off vavles. Blow-off vavles are designed to eliminate this. If you knew anything about the function of a bov you would know it is a possibility this car is stock, it does in fact look like it is besides some aftermarket piping. And that sound, mmmmmmmmm....

[Dinocfs]

no its not stock blow off valves and compressor surge sound totaly different this is bov, you can see the pistons moving if you look

[piperpilot26]

lol the Pistons are internal. you can't see then move. Do you know the anatomy of an engine?

[Dinocfs]

yes i do i mean the pistons of the blow off valve

[piperpilot26]

whoops, my bad lol!

[darkblaze176]

if you see the pistons you have a Fucked Engine!!!!!

[Dinocfs]

no you can see the pistons in a dump valve. not the engines pistons the BOV's piston, read up on how a piston BOV works

[elwlx123]

love that car.. japanese make so many lovable cars!

[TTFAIRLADYZ32]

what kind of BOVs are those?

[Dert666]

sounds like hks ssqv's or possibly greddy type s, but the type s is discontinued so i its probly hks

[smallpaul123]

they sound realy similar to mine i have twin evo dump valves

[DGiles21]

can you get a blow off valve that loud on an automatic

[jasongoody1]

there is no point to having a blow off on an automatic. just learn to drive stick

[DGiles21]

no its not that, i know how to drive a stick but the eagle talon that i found is an automatic. that is why i was asking. but it doesnt matter to me if it is a stick or an automatic.

[SenorMcNasty28]

fail

[Dert666]

transmission type has nothing to do with bov's, ANY TURBO'D CAR should have a bov, the bov doesnt fuction when you shift, it functions when you let off the throttle and in an auto car, where is all that boost in you intake going to go when you let off the throttle? hmmm...seems to me one would need a bov to release that air...

[TTFAIRLADYZ32]

the 300zx has a thing called a recirculating valve which re-routes the air back between the maf and turbo....

[Dert666]

the majority of turbo'd vehicles have bov's recuirculated, you have to unless you have speed density or some kind of blow thru setup, without it recuirc'd your car will run rich because the cpu has already accounted for the boosted air and added proper amount of fuel so the air needs to get plumbed back into the intake after the Maf if not your cpu has now added fuel to air that has been blown out, punk kids r good at not recuircing cuz they think "it sounds cool with venting to atmosphere" lol

[bowlinmaster89]

yes i do for my 2006 saab 93 turbo automatic

[SpecOps1987]

:O

Nice

[fatsocat55x]

damn i love 300's

[psychoninja911]

Tight fit...

Almost sounds like you have a cut in your intake tubing... My friend had a cut in the rubber bend... Squeeled when he built up boost.

[elixier22]

LOL

[elixier22]

bike all the way

[KvizY]

oh yeah!

[killerfocker]

yea bicycle all the way, or the bus

[fabinharaujo]

ENGINE BLOW OFFS 4LYFE

[bonezy09]

these cars are so sick, just amazes me how there not to fast, but still pretty quick. they are sick though

[tknv311]

you should see the power they make with little modification. New Fuel injectors and a good tune and you have not got yourself a z06 catcher.

Life Begins at 20 Pounds.

[julianelmur]

cool car, but retarded to work on.

[Psycho4her]

Strange how that engine fits better in a 240sx engine bay.. like it was meant to be that way..

[guitarmas26]

I love the 300ZX. It's hard to really hear the pure awesome sound of the twin turbos due to the mic distortion. I have heard these driving down the street and hearing the twin turbos kick in is AMAZING. Awesome cars.

[dethpig420]

You're crazy, thats the real BOV sound buddy, not a mic distortion from camera.

[saweet999]

will i get to fuck some pigs if i paste this in other vids?

[BeforeTheNoose]

I'd take a flat four turbo over that noise.

[akrexak]

I agree!

[ubistele88]

mouse farting???zzzz..that its pig farthing

[ZichaMatrix]

no offense but that sounds pretty gay to me... I'm sure its fast and all but that wouldn't scare me if you pulled up next to me at a stop light... sorry I'll stick with my RFL

[TheCottonTop]

Amen brother! There is no misstaking that 3L V6 for a real motor. You know one with torque, which is French of balls.

[SkooledMedic]

haha, that is an awesome sound.

[TheCottonTop]

Are you out of your mind? Sounds like a mouse farting!

[DDDyyySSSoooNNN]

are you out of yourr mind?

[sporadic1]

Nice!!!

[matthbcivic22]

what type of bovs... and where exactly did you install them...

cus this shit sound incredible...

[TEAMALSTARE]

gay

[Deth420]

Lol stfu. Srt-4's are gay.

[rageagainst89]

haha yeah they are

[mascatuM]

great car .. great sound !!!

[0akcliff]

that hoe is terrible!!

[and by terrible i mean really good]

i think that car sound would scare a porshe!

lol

[needspeed96]

Great commant DeathK1ng couldnt have said it better myself.

"

fathan16 that's because a supra is a better car, but a 300 is a sweet car, just goes to show you how great a supra is

DeathK1ng

lol... wow that zx is a nice car... just goes to show how cool my shoes are,,

"

[needspeed96]

Way to compare apples to oranges everyone!!!!

FFS i see to many videos of p fairlady z/300zx getting bashed casue its a v6 and they should get a rb swapped ect ect. shure theres some lagg there but whats the fun of having high boost turboes with no lagg or great spool up sound. this engine is amazing for what it is and in my own opinion is better than any supra or skyline. the only better inline than this v6 is the audi's Sport Quattro inline 5. Still it probably has more lagg on the turbo!

[sdfE36]

needspeed, the reason the ZX needs the RB26 powertrain swap is because the VG30DETT produces too much torque. the ZX is prone to just spinning when you try to take off the line.

i agree, the 300 is a wicked car. i love it, it's one of my favourites and i prefer it over the skyline. a million times sexier. unfortunately, it just sits and spins too much.

[alachamberlain]

get a girlfriend burk!

[LedZepLen]

My buddies got a 300zx and he wishes it had an inline. I own a Skyline and cant get over the crazy fast torque thoes engines produce when you punch it. I love my skyline more then anything and love it's engine and i think it would be a shame afer feeling 300zx power to lag it down with huge turbos. Ball twin Garrett Gt 2535 tubos would be insane on that car.

[nismo1039]

nissan power all the way its me nismo1039 im a fan of nismo skyline z and sivias

[BJWTF]

dont compare this 300ZX with supra! they both a great car!

[ZUL8RR]

the only thing better than a Z car is a 510 ^_^

[tuneRaj]

the ONLY thing better than a Z car is a TWIN TURBO Z CAR

[steffhasajag]

And your point is??

[lynxcattrapper]

LAME is giving it praise..weak!!!!

[XXB4XX]

Best video by far......... on all youtube.. maybe even on earth!???

*Insert sarcastic tone here*

[mariomenoscal]

if you like the sound you can go to your kitchen and turn on your blender =)

[psxman1]

if it will be a twin turbo blender, i'll do it

[psxman1]

i love this sound :)

[putampoco]

yeah great sound

[Magnuspire]

I've never been much for Jap cars but I sure do love them Twin Turbo 300z's :)

[gasser5001]

i <3 my 300 :) may be an 87 but damn it its TT and that baby flies :)

[Magnuspire]

I'll take a mid to late 90's model :P

My buddy has a unmolested 1981 280zx back when it was still a datsun.

[gasser5001]

i love those models too...but mine was 2 grand. the late 90s models are hard to find...much less at a decent price :) i didnt want to spend over 3 grand so...im happy :)

[Bottenhond]

a v6 engine, nice

[gazzat2]

dump valves there called

[dafunkmonster]

you mean "wastegates"?

[gazzat2]

slang for a wastegate is dumpvalve...not blow off valves, unless there fucking farting!

[rugbyallcity]

man that 300 sounds dope

[916bikerboiz]

Nice. What kind of BOV was that?

[yuiyui123yuiyui]

wow

[JRYANG9000]

NICE

[eatmypixels]

Very nice! My next door neighbour has one in Metallic Black. On a note to the BOV's, I couldn't give a toss what my blow off valves sounded like as long as they did the job!

[sandplasma]

What the hell is up with that angry ass mechanic lol

[TurboGoPshh]

I own a Z and I don't think it's a piece of shit.. or hard to work on.. or expensive? It's a very nice car.. Really i haven't heard of many other people complaining either.. Nice Z man :D

[Jaymankilius]

well...its DEFF not a piece of shit, but it IS hard to work on, esp the engine, ESP the TT b/c the engine bay is so crowded. and they are kinda expensive to maintain and upgrade compared to silvias or hondas. I have a tt and i fukin love it. dont diss the car until you have driven it. it drives like butter...

[Neo459]

A Supra would make better sounds ^^

[fathan16]

that's because a supra is a better car, but a 300 is a sweet car, just goes to show you how great a supra is

[DeathK1ng]

lol... wow that zx is a nice car... just goes to show how cool my shoes are,,

[turbotorana]

that was fucking shit

[nissanchris760]

im a factory nissan mechanic from when these things came out, and i know they are fast, but they are the biggest pieces of shit. they are a bitch to work on and expensive to repair, no one takes care of them and they fall apart. unless you are stupid rich or have lots of free time and dont get frustrated easily, they are not the car for you

[Rembetis]

nissan chris you are full of shit...and i bet youre not even a nissan mechanic and even if you are what the heck does that have to do with the factory they came out from? butthead 300zx for life

[artfuldodgerking101]

they should of used apexi bov

[nolimit1982]

gay vid check out "hooker does a backflip"

[OzJustin]

They sound like HKS BOV's. I prefer the Apexi on zeds myself though.

[coutes12]

what kind of bov's?

[coutes12]

what kind of bov's?

[adl16v]

u lucky fuck your farst must sound so sweet then!

[Malakason]

sounds like a fart from my ass

[eatmypixels]

Not being mean here but where else are you gonna fart from? ;)

[fathan16]

haha nice one pixels

[DivideBYZero69]

His vagina?

[tuneRaj]

sounds exactly like skyline gtr

[ahanix1988]

Spartacus you suck. Why the fuck did you post a shitload of short clips about a 300ZX? Just make one or two long ones, instead of polluting the search results and putting in bullshit tags?

[neamtzu]

huh. not bad
