when does Vtech kick in?

i just swapped a D16Zc engine in my 92 civic and i was just wondering when my vtech is supposed to kick in?oh yea its the sohc

ITs not VTECH its VTEC.
On that engine you wont feel the vtec, its a stock sohc vtec.
Vtec kicks in at around 5000, you wont feel anything, peace.

when it goes BWAAAAAA!

i never bothered with vtec.. but hey.. does anyone know if the vtec controller adds significant value to the overall egine control?

It will kick in around 5000, but yeah dude when it kicks in it will haul. Once your in v-tec(h) no one will take you.

what a vtec controller will do will just engage the vtec sooner and you will have somewhat more power at lower rpm. But i dont necesarily no what you mean by engine control

making the vtec kick in earlier wont give u better low end power it takes some away. at low end u dont want agressive cam so that is y honda made the vtec kick in at a certain point. u dont need a vtec controler unless u get diferent cams

i was just trying to make it sound sophisticated..haha anyways i dont use vtec so i was just curious in case someone asks me the same thing

Once your in v-tec(h) no one will take you.

Yeah. With 125 bhp and "v-tec(h)," even Vipers will think twice. :rolleyes:

I dont know who gave u the idea that i wont feel the vtec cuz right before i hit 5000 it goes just like it as said before "bwaaaaaaaaaa" your thinking of differnt engine cause you could sure as hell feel when my vtec kicks in. but for everyone else thanks for the input and yea u guys were right i really do feel it close to 5000

Okay, sense there is a lot of crap in this thread, I am going to post to clear some things up. First off, Flyinlow06, you have a SOHC motor. No, you won't really "feel" it kicking in the way you would on a DOHC. You barly feel it kick in with a SOHC vtec, it's not more pronounced like it is with a DOHC motor. You can feel it on a DOHC for the most part, but not on a SOHC.

Either way, I, as well as some of the other members, get sick of this "vtec ownz" attitude people have. They try and discribe it as this amazing power kick that will waste all other cars on the road and propel them like a rocket ship. That's why you get all those half-ass jokes in here. Look, vtec is a great engineering design and I am not knocking it in any way. It does what it's suppose to do. High lift cams work great for high end power but ideal like crap. Low lift cams don't have the higher rpm power. Vtec allowed for both profiles from the same cam, kind of the best of both worlds. The good ideal and better ideal of a low lift cam, and when the vtec cross-over point comes, the better airflow and resulting increaed power of a high lift cam.

Basically, if you have a DOHC you'll can feel it kick it, with a SOHC, you won't notice much at all by comparison. You have a SOHC ZC, which is basically a D16Z6 ex motor. You won't really notice a whole hell of a lot. I mean, it makes a difference, but it's not this all great noticable improvement on a SOHC. You'll notice a little something compared to your old non-vtec sohc motor, but not this great "BAAAAA." That "BAAAAAA" sound isn't nessarily the vtec engadging. Any car will go "BAAAAAAA" when you punch it and go, go drive an LS and you'll see what I mean. Now, go get in a 99-00Si or a GSR. Drive that, you'll see what me mean you won't notice much on a SOHC vtec. Yes, it's there, but the switchover is not as noticable as it is with a DOHC.

Am I the only one in here who knows zc engines don't have vtec? Jesus...
Flyinlow06, no vtec buddy, sorry.

Actually Ricochet, the DOHC ZC doesn't have Vtec, you're right....but there is a SOHC ZC does. The ZC code is confusing, and th. There are non-vtec DOHC ZC's, non-vtec SOHC ZC's, and a Vtec SOHC ZC. The last one is basically the same as a USDM D16Z6 ex motor. However, in some countries it was called the ZC instead. It's not the motor commenly refered to as the ZC though, that's the DOHC one you are thinking of. For all intesive purposes though, I wouldn't usually call that motor a "ZC" even if that's what's stamped on the block. It's basically a d16z6.

to sum it all up:

SOHC: Not going to feel a difference
DOHC: Not a huge difference but you will notice it

to sum it all up:

SOHC: Not going to feel a difference
DOHC: Not a huge difference but you will notice it

Yeah, that's a good short summary of the often asked question of "will I feel vtec".

Like said earlier, you only really "feel it" on lets say a GSR or an SI, but really what you notice is the sound. And i know any car will make a bwaaa when you punch it but its that sound change when you step on it and you get to 5000-6000 and you really hear it.

VTEC (http://www.leecao.com/honda/vtec/)

Nice little link

Lots of info for nOObs. Especially misconceptions about VTEC.

this was a good post i am no longer goin to mention i have a vtec cause there is no point

SOHC =(

Was the "Misconceptions about VTEC" article supposed to end with this statement: "VTEC is a waste of money."? Considering that the entire site is devoted to explanations of VTEC, the statement seems a bit misplaced...

I have a JDM GSR (B18C) in my 92 hatch.
I dont know if my engine is an unexplained wonder but you CAN FEEL VTEC, and it pulls HARD. I thought it was funny as hell I was giving a friend of mine a ride so he could feel how good it feels and vtec didnt activate, dont know why. Anyways he was like, shit this hatch is faster than I thought. I told him vtec didnt activate, cause I can tell the difference. So anyways on the next light I gunned it again, and it worked and the smile on his hace was priceless.
maybe its the extra upgrades I have which are just i/h/e and hi flo cat but thats my story and Im sticking to it :)

there are different types of vtec and each user will feel it more then others and wat not... i would rather think of vtec as a temporary option until the owner of the vehicle starts to mod the car and then eventually upgrade... maybe even upgrade to forced air and remove the vtec altogether...

There was no JDM GSR...yes, there is a JDM equivelent to the GSR motor wise....It was the ntegra SiR. Now, both the SiR and the Type-R in Japan had engine codes of B18C and compression ratios of 10.6:1. However, as we know, the type-r put out more power. However, if you have the jdm equilvent to a GSR motor, it's not a JDM GSR, there was no GSR in Japan...it's a JDM SiR B18C motor. That was their "GSR" in Japan. Just thought I'd correct you.

the only reason I said that was because everytime I say B18C people ask wether its a gsr or type r, b18c1 or b18c5, and that helps clarify but thanks anyways.

Ok, I know what you are trying to say. In the US, the GSR had a B18C1 and the Type-R a B18C5, so he block code was different. In Japan, the SiR and Type-R had a B18C block code (no number after it), so it get confusing to some.

I'm just a stickler for correct termanoligy sometimes. Tell them it's a JDM B18C SiR motor, then they'll know it's the non-type-r and you'll be correct, lol.

thats cool man, to be honest I didnt know about the SiR all I knew was that jdm type R and "GSR" had same engine codes except the only thing that was the same was the block. Now I know my "GSR" ir really an SiR. This gives me a good reason to get that little SiR sticker that Ive wanted to get for ever for my tailgate but havent done it because I thought it would be rice to put a sticker of something I dont have.

LOL!

hahaha I think im going to pee myself,

o man, those are the best pics in the world. that post didn't even need any words or explanation, it's brilliant. i can attest to the fact that vtec is noticable, my brother has a b16 in his crx, and i can tell when teh vtec kicks in at 5300 rpms. not the matter that it's faster, just the engine sounds different and soooo much better.

yup funny pics i always wanted to see how i look when it kicks in while i drive now.... i kno =P

And I thought Vtec was a tame animal, Now I know its a wild beast

just to give you an idea, on a wet road I gun it in 2nd gear and when vtec kicks in I loose traction... its pretty sweet!!

Yeah but, You can do that in non-vtec cars as well.

Yep, did that when the roads were wet. Hardly spun though.

I know if you have enough power you can spin through third in a wet road, in fact I can do it if I revved hard and shifted into third but Im just saying the difference in power when vtec activates is enough to cause me to loose traction even after I already had traction in second gear (on a wet road)

3rd gear wet road sure you can churp i churp 2nd on dry road everyday when its gunned

Yeah but, You can do that in non-vtec cars as well.

i agree. i think that guy doesn't even own a vtec-powered vehicle.

or he's just retarded. :chair:

right I dont have a vtec in my jdm b18c and Im retarded and thats why Im majoring in mechanical engineering.

by the way to clarify Im not talking about chirping in second gear. I can spin all the way through second gear if I dont control throttle on a dry road. Im talking about going 20mph in second gear and floor it. and if I do have traction I will loose it once vtec activates. Im not saying you cant do that in other cars, we were talking about feeling the difference between before and after vtec. is that hard to understand?

See thats y i hardly post becuase all i ask is a simple question and what i get is a bunch of arguing but for the people that posted without being sarcastic, thanks, i just wanted to know if anyone that syas i wont feel the vtec has ever driven in a car with a ZC? because its really strange when a lot of people are saying that i wont feel a thing, because honestly guys when i drive it or any other people do they all feel it.But NO disrespect at anyone and thanks for the input

ok i have a D16Y8, and I'm sorry, I didn't even know I HAD vtec until i was clarified that the EX model of 96-98 were vtec equipped. Nothing sounds different, my car doesn't warp into lightspeed, or anything else remotely close to "feeling" anything. That's not vtec you're feeling in your ZC...

You are a tool.

That's because it is a SOHC, vtec changeover is a lot fiestier in a DOHC.

I have a 2002 Honda accord se with the 2.3 ulev vtech motor and i can feel the vtech kick in at 4500 rpms

are we done here? This thread seems to be going the wrong way....
