Dual Stage Vtec?
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...
its not technically dual stage its just your secondaries opening
97ek hatch
lol
my gsr hits vtec over 6 times...wrap your mind around that
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
Who knows?
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

One is for full throttle, the other is for part throttle. That ecu will probably blow your **** up too.
Damn, vtec owns the world. Lolol.

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.
VTACH FTW.
<---Click it.
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.
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.
this explains vtec better
1st stage
2nd stage
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 lolthis explains vtec better
1st stage
2nd stage
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...
So apparently he ****ed up my vtec...is what u r sayin
no, vtec' ****ed you up
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
Bcuz i have been buying a **** load of oil recently...
are you eating it?
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 =)
ha, i dunno about eating, but the car sure has been getting low on oil alot. No leaks or anything though...
THATS WEIRD.
umm its called u are buring oil
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.
Who knows?
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 ?
idk but on this gsr i drove one time , i could of sworn vtec hit at 4500 then again at 6
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
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!
I want that sh!t sooooo bad...too bad I'm poor.
why not just make vtec hit all the time lmao
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
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
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.
Who knows?
