Dual Stage Vtec?

[rude_lude911]

I have a huge question that I'm confused on cuz i'm hearing too many yes's and no's. Is it true that there is a dual stage vtec? I just bought a skunk2 p72 ecu off eBay and the settings were: Vtec:4500 and 5800 and redline @ 9600.

A friend said that it's impossible cuz vtec doesn't engage twice after engaged...
Another said yeah, but it's called the butterfly setup, having to do something with your intake system...

Any of you guys know anything about this, lmk...

[killerdx]

its not technically dual stage its just your secondaries opening

lol

my gsr hits vtec over 6 times...wrap your mind around that

[Z0_o6]

IMRC- Intake Manifold Runner Control

it basically varies the length and diameter of the intake manifold runners by having two separate routes for the air to go through. It uses butterfly valves to do so, and is engaged at the earlier of the two RPM's

[southside]

yea i dont realli kno the difference either but my understanding is that vtec engages at like 4500-5000rpm but it gets louder at like 6000rpm unlike b16 and type r they scream at like 4500 thats how everyone expland it to me

[josh green]

One is for full throttle, the other is for part throttle. That ecu will probably blow your **** up too.

[Maniaç]

Damn, vtec owns the world. Lolol.

[rude_lude911]

One is for full throttle, the other is for part throttle. That ecu will probably blow your **** up too.

probably so...I mean i've got a B20Vtec setup and i usually use my LS ecu for it. But my vtec hits hard as hell cuz the guy who did my B20vtec setup ran more electric currents to it.

[Whiteboy™]

VTACH FTW.

ok i hope u were playing about that?

[rude_lude911]

ok i hope u were playing about that?

nah, tell me something i dont know. Cuz i mean after completing the setup, it ran perfect. And my vtec was engaging at 4500 like its suppose to. Then after about three weeks, it wouldn't engage for nothing. I mean no vtec at all. Then took it back to him and it wasn't the wiring or ecu cuz i used a stock p72. But he rewired it to where it would engage and he said he ran more positive currents to it so it would hit harder.

[Benefit]

lmao for real

LOL LOL LOL LOL LOL LOL

am sorry but by adding more power ur vtec aint going to hit HARDER. my 2 cent take ur car somewhere elsa.

lol have u checked ur head light and vtec fluide? hahaha

btw if ur car wasnt hitting vtec check the oil if u are low vtec wont kick

lol wish i could rep u lol

[Benefit]

yea if oil is low , it will go into a safe mode and wont send oil to the head...

but also could be your solenoid going out...i know mines is and will only engage sometimes...

i "heard" it for the first time today...going to go buy another one tomorrow...

[rude_lude911]

So apparently he ****ed up my vtec...is what u r sayin

[Benefit]

no, vtec' ****ed you up

[drmcivicsi]

idk i havent seen the car. but by adding a big power supply aint going to make it hit harder. vtec is vtec unless u get a built head

go there he can help u, or mainstream/turbodave

[rude_lude911]

Bcuz i have been buying a **** load of oil recently...

[Benefit]

are you eating it?

[drmcivicsi]

lol sell the car man if u dont know what u are doing ur self sell it. cuz by ur post we all know u are a cheap ricer that took it to someone that didnt know what they were doing b/c it was cheap go die in a fire =)

[rude_lude911]

are you eating it?

ha, i dunno about eating, but the car sure has been getting low on oil alot. No leaks or anything though...

[Benefit]

THATS WEIRD.

[drmcivicsi]

ha, i dunno about eating, but the car sure has been getting low on oil alot. No leaks or anything though...

umm its called u are buring oil

[vancem3m3]

it takes a GSR p72 ecu and a GSR manifold to get the duel stage vtec. the first one you hear is your vtec oil pressure switch the second sound you hear is the butterflies opening up on the inside of the manifold witch gives more air and with more air more power and sound if you dont have this manifold you dont get duel stage i switched to a skunk2 and it made more power and vtec hit loud and hard 4800 rpms

uhh no. you have it backwards. the imrc activates first. also the vtec pressure switch makes no noise, the solenoid causes the actual changeover.

This guy is wrong, there is a dual stage vtec.

This guy is right, there's a butterfly in your intake manifold that opens up or something at a certain RPMs..

can u plz tell me how vtec is duel stage ?

[Benefit]

idk but on this gsr i drove one time , i could of sworn vtec hit at 4500 then again at 6

[drmcivicsi]

when u hit 4200k u heard the vtec pressure switch kicking in at 5XXXk vtec kicks in how it that dual stage? between 4200k and 5,xk thats not vtec

[JDM onlyy]

can u plz tell me how vtec is duel stage ?

Okay, well its not DUAL stage technically. Its that little intake runner thing. The only time VTEC really hits is when the solenoid actually engages, so I guess technically no there isn't.

But there is a 3-stage VTEC! :D
I want that sh!t sooooo bad...too bad I'm poor.

[Benefit]

why not just make vtec hit all the time lmao

[xlilvi3tx]

lol well u basically getting the same thing u already know right now. lol some people is tellin u vtec hits twice and some people tellin u it hits once. i have heard that there is dual stage vtec on gsrs somewhere but i dont know if its true

[JDM onlyy]

why not just make vtec hit all the time lmao

Cause then wouldn't you just have a higher lift LS?

VTEC is made for the higher part of your powerband...so that the engine can keep making power.

that sounds about right

[Z0_o6]

there is so much misinformation in this thread it is disgusting. 3 stage vtec is strictly SOHC, so it is actually cheaper because it is on undesirable motors. you can't make vtec "hit" all of the time because then you defeat the purpose. and, again, you don't hear the switch. you hear the result of the solenoid allowing the flow of oil to change the camshaft profiles, inherently making the engine sound different.

edit: i just don't get what is so ****ing magical about vtec. it is nothing but ingenuitive thinking being applied to and engine to gain the "have your cake and eat it too"

i guess thinking outside the box is amazing to some uneducated simpletons.

I never said it was on a GSR you dipsh!t. I just said there is one and I wanted it. Get your sh!t straight

Edit: Who said VTEC was that amazing? If you don't like VTEC that much then sell your RSX...I never said it was the almighty powerful and great VTEC, its just cool to have. It does give a significant power gain and yeah it is pretty smart. (ingenuitive isn't a word...) But you weren't the genius that created it were you? No, so stop acting like a smart ass and just give out straight info without the BS...Thank you and good day.

LOL at reading comprehension. so you would rather have a SOHC economy-based engine over a GSR because it "has more vtecs" ??

[JDM onlyy]

Lol haha, yes I would rather have a SOHC economy-based engine over a GSR, not because it "has more VTECs"...its because it gets 58 mpg...Lol. Like I said, I'm poor. I need to save as much gas as I can. And it still makes as much power as a d16z6 so I think its alright... :tongue1:

[drmcivicsi]

not u it sounds like u know what u saying

[Z0_o6]

58 mpg wouldn't be too bad. hell you'd at least be using it for the right reasons... unlike some geniuses around here.

i want vtecs

Lol, yeah...With gas prices these days, it sounds like heaven. :D

I choose my motors for reasons...not cause everyone is doing it...or because it has more "VTAK" Lol.

damn i missed my chance on a rebuttal for this stuff. ninja edit slipped right by me.

but here goes anyways... RSX was sold back in april. ingenuitive was my spinoff of ingenuity, typed faster than i thought. it is straight info, straight from honda. :tongue1::tongue1::lmfao:

Bah...come on hondabuilder I expected better from you. If you want to argue symantics, iVTEC has 2 stages, because you've you got your VTC and then your standard VTEC.

[wunquikser]

VVL >> vtec

my shiet kicks in twice..

[mxglory258]

LOLOLOLOL This thread is amazing. Vtec was created for a gas saver, power if you need it, gas saving under 4.5k

I thank you for creating this thread. Myself, and my dad, who knows NOTHING about vtec, are laughing almost un controllably.

[Z0_o6]

well since you wanna argue sEmantics... :D

VTC is not a "stage" of vtec, is continuously varies the phase angle of the intake camshaft, therefore is a completely different mechanism that operates hand in hand with VTEC. iVTEC is nothing but a marketing name.

[Doppelgänger]

VTEC = Various Ticking Engine Components ....... duh.


I put VTWE cams in my Mazda (because the cams themselvs are made by the same company). It worked great. But they'll only work really good after i change my oil to VTEC enhanced oil. Regular oil does not work as well with engines that have VTECH. You must use Dynotech 62c05wv oil to get the most out of your VTECH.

[gtikid]

why not just make vtec hit all the time lmao
