'91 Nissan 300zx Twin Turbo 390RWHP (Strice) 13psi

[mongoosecage]

love ur 60 to 80 man...

[MrThemetal169]

YOSH!!!!!

[aodosod]

lol that 1-2 shift sounded like it mechanically raped your car

cool tho! needs more boost ;)

[penaguay]

damn im running 14 psi on mine and can boost it up to 18 with boost controller.

never dynoed it! has every single mod dat can be done except for internals..

im wondering how much i can put down with 14 psi, or 18?

any guess????

thanks!

[JaymezSPCM]

@penaguay I wouldn't do 18psi too often w/o internals. Thats asking for trouble.

[dynodrew44]

@penaguay there is an easy way to find out... you could dyno it and let us know :-P

[dummydoo93]

damn that thing can haul

[shanehbb]

gogo

[1993z32]

what rear tires were you on?

[robertuemura]

295/35 R18 BF Goodrich KDW's New Tread

[1993z32]

@robertuemura

looks like they were hooking up great! I've driven TT's with 350whp that don't hook 2nd like that

[chittchitt1]

@robertuemura do you have a widebody kit on the z? I cant imagine 295s fitting in the well.

[palefaced1]

Gotta love that stock boost gauge : )

[M0tleyFreak]

Cool video! Wish I was in the passenger seat, haha. Z cars are the best. Used to have red '90 Twin Turbo

[PrimitiveStrikeForce]

whats the negative thing mean on the boost gauge?

[conwa23]

vacuum

[cliffkemp]

when there is not a load on the engine the pressure in the manifold is actually negative until the boost builds enough to cause positive pressure in the manifold. the turbo size is a factor as to what rpm boost will start to become positive. It is usually around 2k when there is a load (press gas pedal way down) on the engine. when you press the gas you are acutally just allowing more air to reach the engine.

[TheLeeno]

@PrimitiveStrikeForce vacuum instead of boost

[timesareturning]

vacuum.

[wilco9000]

nice figures there :) i miss my old tt

i hope that check engine light doesnt mean anything too serious :/

[TheTruckV8]

jusz hehe

[robertuemura]

I have stock(HEAVY) Pulleys, & 2piece driveshaft still........

+ I have 18x10.5" n da rear wit 295/35 18

BF-Goodrich G-Force KDW's 

Look @ my parts list.

[ir655]

Love it, I miss driving my brothers Z32TT.

[robertuemura]

Ur an Idiot!!!! That's y they are called "Twin Turbos," because both turbos produce the same amount of boost. + The TT Z's r really define the term "TWIN" -2 Turbos -2 intakes -2 Blow Off Valves -2 Intercoolers -2 Individual piping from downpipe to Exhaust Tip. + 2 sets of Intercooler Piping Don't 4 Get!!!! 2 Throttle Bodies 2 Sets of Camshafts to = 4 in Total 2 Sets of Cam Gears to = 4 in Total

[Cdude121]

Holy crap dude!

[theabyssishere]

A Twin Turbo 300zx's speedometer really tops out at 160?

[robertuemura]

YEP....

[kricel92]

thats a nice car dude and awesome engine god job !!!!!!!!!!!

[plzzzdontsnitch]

how much boost runs in a stock twin turbo

[robertuemura]

8 PSI

[KillerKyle94]

@robertuemura can you get more boost out the stock turbos

[robertuemura]

3 Basic but main contributing factors to achieving High Boost.

1.) Stock Injectors 330cc's Maxed out @ 13.5/14PSI

2.) Stock Internals Pistons N Rods Mainly can only hold between

400-650+RWHP (RARE with Perfect Tuning) Z32power.com

3.) 91 Octane Gas (CALI) starts to have detonation after 15PSI so u need

a Meth Kit/Race Gas to go beyond that, but always have proper tuning.

& of course your turbos Ultimately decide how much PSI u can BOOST after u solve these 3 issues. OEM turbos Maxed@17-19PSI

[robertuemura]

All Refer To OEM VG30DETT Nissan 300zx TT Engine & Turbo Setups.

UPGRADED/BIGGER TURBOS, MEAN MORE AIR, MORE BOOST/PSI,

& MORE POWER!

[Piperporsche180944]

not bad

[chinsta90]

sweet

[kluelessblu]

beautiful

[niz55]

what kind of turbos are you running?

[hockeyprep22]

HOLY SHIT

[LazyGuyYawn]

very nice, wats the CEL light on for?

[robertuemura]

Exhaust Temperature Sensor

[GiNgErDoVeR2010]

good spin in 2nd.....i can usually catch a sqeel but not spin real good in second. still gettin adjusted to it and workin on it i have a 300ZX mines a 87 though

[twistymcslide]

sure hope you have better oil pressure than what its showin..

[Andrais]

hmm nope his oil pressure is alright . If the car is warm.. if thats it when its cold id seriously be doing an oil change or checking levels but for a Z warmed up thats fine.

nice wheel spin hitting 2nd ;) haha.:D

and Hitman what your friend may ahve been getting at is he needs a TURBO timer to stop the oil "COOKING" in the turbo's if you turn the car off straight after stopping. should always let a turbo cool off for at least 30 seconds after driving.

[JRDilated]

thats normal among 300zx anywhere from that range to about 100psi ..its in the owners manual..but his check engine light is on lol

[TheHitman1990]

Nice sound! I have a friend who bought this same car a few months ago and he told me that because of the turbo, you have to be careful before turning it off because it may start to overheat.

Favourited and suscribed ;)

[geedunk13]

what, that makes no sence how can it overheat once its off

[xcracer2]

The car has what's known as a turbo timer. after you take the key out, the engine runs for 60sec to cool the oil in the turbos so they don't wear prematurely.

[kraziwyteboy]

The reason you let it idle a couple minutes before shutting it off is to let the turbos slow down and stop spinning. Shutting off the engine shuts off their oil supply,don't want them spinning with no oil. Ball Bearing turbo's don't have this problem.

[nathanpisces]

yep! that's why you get turbo tiers, so it knows when to turn the engine 'off' we had that problem on our old S14 200SZ we were going to put a turbo timer on it, but we just sold it instead lol, got a 4.0 straight six, TWR jag now :p

[scbca]

pretty frikin nice

[AsmodiusMKII]

thats pretty quick

[handoggn]

Sick Z man sounds so quiet @ idle, but RAW when u rev her.....!

That noise is a diconnected hydraulic lifter

1 of ur 4 valves isn't going up any more that's y ur engine light is on.

U Shift ur Z @ 7K so High revs stress the lifters, and cause them to disconnect.

Happens all the time to the Z's lil bro..the SR20DET

Not that big of a deal though (jus labor).

[3star2nr]

yosh!!!

[nightrider2693]

i have a question. ive been lookin at 300zx's a lot lately. but i see that most low milage ones are automatics and theyre cheaper. how much did u spend to change over the tranny?

[helloimsonik]

You're better off just buying a 5 spd, my opinion.

[chimaera1855]

what else did u do to that engine???i am getting my Z next month tt but fully original.tks for ur help i am looking at around 3++hp reliable.

[nickma71]

Was he short shifting, or are they geared that short?

[JRDilated]

actually 300zx gears are kinda long lol u can take 3rd over 100mph.. anything over 7k is risking engine ..it dont bounce off the revelimiter at 7 but i alwasy shift a bit b4 7.. like 6.7 or 6.8k

[Pogost1ck]

Youre right, theyre wrong.

[lilweezyana89]

u only have an intercooler if u have a turbo if u dont have a turbo than u dont have an intercooler tht simple

[boydubbs306]

or supercharger

[josieonetoothh]

HAHAHA, quit while you're behind

[koukicrisp]

Wow you are completely clueless to anything automotive. Meth would do what in a NA car? Please be quiet you have truly embarassed yourself.

[11jstedm]

accually you can do alot with meth in an n/a car. You can increase the compression greatly and advance the timing up the waz. it greatly increases the cylinder pressure. plz don't flame people as you have no idea what you are talking about.

[SpdDemon69]

yea i got in an lil fight with this dickhead cuz he thinks he knows wat hes tlkin about....

[frickinkraut]

You can't increase compression without changing the internals, fucktard.

[twiceasfastasyourass]

goddamn... i drive an e36 BMW M3, and i STILL miss the power made from my 300ZXTT... mine was at 367bhp, but it still pulled HARD... man i need to turbo my M3, im missing booooost

[wadesta1986]

Whooo Mumma!!! Got Boost Or What?! Thats awesome man! Real nice sound too!

[corykorn]

sailorjason, you are a fucking idiot, turbo is not the same as all motor, and nos is nitrous, go suck you daddys sausage some more little guy!

[mkIIIsupras]

sailorjason go to hell, your fucking stupid

[robertuemura]

Thank You mklllsupras..!

Finally someone who knows what ther're talkin bout.

[fumpfy]

Hey i just got my 91 300zx TT about 3 days ago. its mainly stock. what did you do to get it up to 390 hp dude fill me in!

[robertuemura]

Look at My Parts List Vid

Twin Turbo 300zx Video (Strice) Parts Pt.1

Twin Turbo 300zx Video (Strice) Parts Pt.2

[robertuemura]

I Just Need 3 More Parts and I should be @ least 550whp.....

-Full Unorthodox Pulley Kit

-Nismo 740cc Injector kit for 89-91 TTZ's

-Aluminum, or CarbonFiber Driveshaft from Z1, AMZ, CZP or PST.

[specialrecipe]

One thing you should change in the UO Pulley kit is the water pump pulley. You should get the overdrive water pump pulley (Blizki H.I.) My Z runs way cooler than before and less damaging to anything under the hood and boost runs more consistent because it reduces heatsoak. I have the UO pulleys too but replaced the water pump one.

[Fubar231]

GO with a carbon fiber driveshaft. Just make sure its balanced correctly before installation. Ive heard GREAT things about CF driveshafts over Alum ones. Also, ever think about going big single turbo?

[nickgloege]

Why kind of mileage do you get when you push your Z hard?

[robertuemura]

I got stock injectors 330cc so proabably 5-12 mpg on highway at 4500-6500rpm...but that's hard driving almost redlining. Engine won't last too long.

Even with all of my mods, i shift at 2000rpm when conserving gas, and my Z gets like 24Mpg...which is really good for a Twin Turbo Sports car.

[robertuemura]

No nitrous/meth, what about water injection did u leave that out 2.? & Y not mention Co2 spraying on intercoolers,O ya intercoolers are only on boostin cars not AllMotor cars.

Cmon buddie do ur research. Only Boostin cars use meth Idiot. So thats still a turbo/supercharged car, making it not ALLMotor/NA.

Street racing rules are not hard. No Meth? Peeps have meth kits so that they can boost higher on pump gas without detonation. Higher the Boost the more HP. If U have boost ur not AllMotor

[Fubar231]

for the retard above. All motor means NO FORCED INDUCTION. (Supercharger, Procharger, Turbocharger, Nitrous) Anything that has any of those i just listed, is not ALL MOTOR. N/A - All Motor (Naturally Aspirated). FI - Boosted Cars (Forced Induction) Stop watching Fast and the furious and learn something real about cars.

[nemo1080]

lol u list supercharger and procharger as 2 different things.

[frickinkraut]

No, a 'procharger' is a centrifugal belt driven supercharger.

[missmindymay]

haha, procharger is a supercharger. and nitrus isn't forced induction...

[miamichika]

Nitrous is a form of forced induction

[coandca121]

So is my pen1s entering your mom.

[888TAY888]

top cunt lol

[Derpinguin44]

Forced induction is stated as air being pushed inward, a fuel cannot be a forced induction.

[ejhieviugiejbv]

nitrous is a oxidizer not a fuel its a pritty common mistake no big deal dude

[duvall375]

Nitrous just ups the amount of oxygen that can be burned, which ups power.

[HeimlichkeitKJ]

Nitrous, like supercharging and turbocharging is a method of delivering more oxygen to the combustion chamber than would be present in an un-assisted condition. So they are all classified as forced induction.

Nice Z. Don't rev so high, you've got plenty of torque to work with.

[dafunkmonster]

nitrous burns exceptionally well, and injecting it cools the intake charge which means that you can run higher boost levels when under nitrous.

[robertuemura]

Idiot... Whos talking bout boost? Im talkin bout if u boost or spray its not Allmotor for any car. Allmotor means N/A,Muscle or Rice. When u add Turbo, then its no longer Allmotor. As long as u dont boost/Spray, u can do anything to the motor.

- Stroke,Port & Polish,Bore,Hybrid Motor TypeR Headw/LS bottom half,to get most HP/lbft.TQ out of any Integra Motor)Of Course Bolt Ons too. Just No Boosting or Spraying. Ive seen & raced 250-650hp+ Allmotor Cars. From Honda Hatches, to the Z06s&Camaros

[Drumpowa]

To anyone who has a Z32 TT, I'm in the process of buying one and I hear that the stock boost guage on the is highly inaccurate, that's my most get aftermarket, ist that true?

[robertuemura]

where are u From....? Cheaterville..?

Whoever considers Nos as ALL Motor is an idiot, & proabably races for money, & says he's all motor when he's spraying. Maybe u Honda guys out there consider NOS as all motor, but if there was a vette, or camaro spraying, 50 100 150 200 even 250 shot, would u consider that all motor? Some NOS kits give u more power than turbos or superchargers. So how is NOS All Motor?

They mark ur car @ the track to see if it's Nos equipped or not, to change ur drag class.

[specialrecipe]

Man, this sailorjason guy is clueless and hasn't seen an actual "nitrous" bottle before has he? I can't believe he tried to correct you with NOS vs. nitrous.

Sailor Jason. NOS means 'N'itrous 'O'xide 'S'ystem.

[matthbcivic22]

hey.. how is your oil psi so low?

on my z it will reach up to 120psi @ high RPM

[robertuemura]

that's how me and my buddies TT Z's are, and mostly everybody i know who uses AmsOil 10W-40

[escobarerick]

hey were did did you get the rings that you put around the gauges

[PPKLU]

i'm new to cars, and i was wondering what the psi indicates(noob i know)

[robertuemura]

psi means pressure(pounds per square inch). Doesn't just apply to cars. Usually turbo's, blowers, and superchargers, all force air in to the engine.(force induction) This rate/pressure @ which the air flows is called(psi)

But your engine oil, is measured in psi, and so are your tires air. PSI is everywhere

[PPKLU]

you may laugh at me, i actually have 91 300zx TT as well. i used to have a 94 sentra xe, so..i'm new with cars and i've only had the Z for a few months, still learning a lots of the stuff on the dash.

i've google psi before, i knew it stands for psi but, what difference does it mater when the psi is positive or negative, again, don't laugh at my noobieness :(

[robertuemura]

Turbo's have intercoolers/pop chargers..etc to increase the air travel from beginning to end so cooling will happen. Because of this, when u step on the gas, it takes a split second for that air to reach ur engine . (Lag) -PSI

The second that air gets into your engine, it starts becoming more and more +PSI (No Lag)

[PPKLU]

so let me put it this way, turbo PSI is the amount of air thats tranveling into the engine, the high the PSI the faster the air are going into your engine?

[robertuemura]

The air is traveling faster because ur turbo spools up more and more, but the air coming into the engine is also getting denser as well as colder when it's reaching peak boost.

more speed = more wind = more cold dense air

[jllego]

Ok... you do have a pretty good grasp on the turbo idea but you are off a little bit. pop chargers are more of a nissan thing not turbos. Also the lag from having vacuum in stead of pressure is due to the exhaust not spinning the turbo fast enough yet not how long it takes for the air to travel through..

[specialrecipe]

It's the amount of air that's entering your engine. PSI stands for Pounds per Square Inch. So it's the volume of air prior to combustion.

[muskaa9]

how much

[robertuemura]

used to be an Auto 91 TT with 196,000 miles for 4 $3,500.....Then I ripped out old motor/tranny & put in... JDM Motor/Tranny 5spd (55,000 KM) JWT ECU JWT Single Pop Charger JWT Aluminum Flywheel JWT Severe Duty Clutch JWT Sport 500's (Turbos) Greddy Profec-B Boost Controller Stillen Side mount Intercoolers CZP Downpipes 2.5" Testpipes Borla Exhaust SSR D5-R Rims 18x9.5F 18x10R a lot more parts not mentioned due to lack of character count........

[muskaa9]

how much you pay for it

[montoyabiz]

are you sure u dont have a knock sensor issue? or any kind of ECU code.. (your CE light is on) You probably are on "safety boost" .. U barely reached "10psi" which is more like a 7psi (safety boost) (stock gauge not being accurate)... you should check your codes.

[DriftZ07]

were u relly on 13 psi of boost or was it stock boost on that run?

the stock gauge looks like its 13 but its relly 9?

[robertuemura]

I Have a Profec-B Boost contoroller, and @ the time of the shoot, My Profec-B was at 130 on Hi and 100 on Lo. (13psi) & (10psi)

My stock gauge isn't accurate for some reason. I don't know... why..though. I have to have EXACT Motorsports take a look at it 4 me.

[nathandonner2]

You may already know this, but the stock boost gauges on z's are notorious for being a few psi under the actual number. car sounds good and definately seems quick nice job

[x3Dopeyx3]

do u think a a stock 300zx tt could take on a 300hp integra?

[robertuemura]

If Integra is Boostin or All Motor, either way it should be able to play with the stock TT Z.

[CanabusSmoker420]

lol what you sayin in the beggining? all i hear is yoosh. wtf language is that???

[robertuemura]

Japanese...lolz.....I'm..sayin­....Yooosh..Nippon...Power

[robertuemura]

My Parts Video is up now....

2 parts.........

[lltt916]

what type of guages do you have?

they look really nice, wher ei can get them

[rob10s2]

i think those are z32 stock guages

[robertuemura]

Wrong.....Stock Gauges w/ Polished Aluminum Gauge Rings

[suprachink]

yeah, my z got that "check" warning let on when  i was trying to push it hard. a mechanic told me coz its running lean, a/f ratio need to be retunned . correct?

[robertuemura]

yep, but i have no cats and a lot of parts!! So Which One is to blame?? (LoL)

[aidemsined]

i dont think you get a CE for running lean. evet detonation sensor doesnt do CE.

you might wanna look into that - im running stage3 with downpipes and testpipes (no cat no precats)- no CE codes (knock on wood)

bottom line read the actual code and see what it is. dont let that car die man

[robertuemura]

I have full exhaust, (downpipes)(which kill O2sensors) which make my engine light come on and off depending on how much exhaust is blowing by my O2 sensors. watch ur 02 sensors...cause u'll eventually end up in my shoes. Right Now my engine light is off too

[robertuemura]

& I think My Profec-B Boost Controller reads 25% (13psi) and 15% (10psi)

[ir655]

Can't trust those gauges...need an after market oil press. gauge to get more accurate readings. Nice Vid again.

[ZTHIRTY2]

fuckin love it man! im tradin in my z32 na to a turbo one wit all the mods u can think of!!! nice z

[JTuneR]

might wanan check your oil? ^-^ just a thaught, dont want to see a z getting hurt

[robertuemura]

Video was takin in Z with 1700 miles on Synthetic AMSOIL 4.5 Quarts
