Nameless RB26

RS_91

JReed

JReed

i did a search but nothin came up. so which is it 5200 or 4000

kommon_sense

nah, the ex has regular vtec.

I hear mine kick in around 5000-5500rpm. As I understand it, there has to be a number of conditions met before vtec kicks in, so I don't know that anyone can tell you exactly the magic number.

when u stomp it , it should kick in at 5,700 but not quite sure when u slowly go into it. atleast thats what HONDA said

Mr. Thunderlips

Uh, I don't think so dude. EX is D16Y8, normal VTEC motor by most standards. Now, if we're talking the HX model...That's another story.

Racerage1

HX=VTEC-E
EX=VTEC

on your car it should kick in at 5500 rpm if its warmed up..but on SOHC's you can barely notice the changeover...

its really hard to tell when vtec kicks in a sohc, but I would think around 4500-5000?

clm

What he said. VTEC on my D16Y8 is barely noticeable when it kicks in around 5400 RPM.

on my old Z6, i could hear VTEC engage at about 5500 RPM's. to actually hear anything, you'll need a short ram or CAI.

VTEC only works on the intake side of SOHC's.

WongFeihung

in my si, I hear it around 4500..but i cant feel nothin LOL. yea, if you really want to hear it, get an intake.

vladd

5500 rpm. get a short ram intake and you'll hear it.

GARBhatch.

exactly on my friends ex you can't hear any solenoids kickin in. like he said if its warmed up and the ecu determines that road speed is correct, then it will engage v-tec. just know its there.

f1uxx

its about 4500 on my 98 sohc vtec

ok, the HX is the vtec-e, my bad.

The GreenD16

5700rpm i believe

clutch33

I have a 2000 civic vogue silver Ex, andI think it kicks in around 4.5-5.2 or so.

vladd

i have a 98 y8 too, its 5.5 man...

Turbo'dMex-A-Keen

On 96-00 its between 5,5 - 5,7 just depends on the pressure and tempature; no 96-00 kicks in at anything lower than 5,5 unless u have a vtec controller which i wouldnt recommend u setting it to any lower than 5 unless u want lag.
