05 models and vtec

Is there anybody out there with a 05 model?
I'm told that vtec kicks in after 6000 rpm, but I don't find any noticeable difference. I know the models have changed from older to new, but I'm just wondering what the fuss is all about, or is just me?

I got an 05 s2k but mine is F20C engine

I guess in US (not sure) 2005's are 2.2litres that might happen in those ones

i have an F22 '04 (US model) and mine kicks in as expected at 6K...

are you pressing the gas all the way to the floor??? - you should feel the "surge" as the cam profile switches over.

plus make sure the engine is warmed up first - since vtec operates on oil pressure...

these are the only 2 things i can think of...good luck

You have to be flooring it to really feel the vtec. But be careful when doing so it's addictive

u should also hear the scream from engine ! but if u change u r intake and exhaust the sound of those will cover the sound of vtec so is harder to notice.

I have a 2001 s2k and i dont even have to be flooring it to notice a very strong kick at 6k rpm. Its pretty noticable and doesnt require any special driving technique to feel. i dont know about the 2005 though

Enlighten us on this stament.

Are you saying that JDM S2K's (any year) have a different ECU that magically produces more torque from the F20c than the USDM? That motor has the exact same output regardless of market. The F22c produced only for USDM in 04-05 actually makes more peak torque and does so earlier than the JDM F20c in the 04-05.

Hi all

i've just put down deposit for a S2000 myself

i test drove a brand new model from Honda, had 1,300 miles on clock, the Vtec wasnt as great as everyone had said it was, i felt no noticeable change in power when foot to floor, and this was up to 8-9krpm!

i however, took out a 99 model, and the difference was suprising! the change when vtec kicked in was amazing, and the car just wanted to keep going!! reaching 70mph in 2nd! :P

i heard that the new models of the S2000 were detuned compared to the older models as so many S2000's were written off by inexperienced drivers??

dont know if thats true... but felt like it when driving these two cars

few pics of the S2000 i getting, and my mates black Civic TypeR :P

A new car that just had it's breakin period and propably was never or little driven hard will be much slower then one with many miles and used to be driven hard.

It could be that, not sure.

but have u guys read the reviews from v-tec temple ? they make it sound like the 2.2 liter engline is much better in performace torque and HP ... just based on that its said there the F22c is much better

I would like to know the difference between F22C and F20C2 engine
in terms of parts
so may be if I can find those parts I will change the my stock F20C2 parts with F22C in Us
then my car will be F22C as well

thats what I am thinking about but I saw the techincal data there is not much gain for all this hassle

is defenetely not worth it to me, it cost alot on the labour just to expand the holes, and if they didn't do good job, there is nothing u can do to reverse it.

Same question here.
I drive the 2004 2.0L European model wich does 9000 rpm.
I have driven it for 13500 km now and have manytimes tried mostly in 2nd and 3rd gear and paying attention when i should notice the v-tech kick in but i can't notice any difference.
When i start around 3500 rpm and pull it to 9000 rpm i notice the engine going harder the more revs you make but when the v-tech should kick in between 6000 and 7000 rpm i just don't know.
So is it like a real boost i should feel??
I don't.

Ok, in the meantime i gathered some info from an s2000 nut that the s2000 doesn't deliver a v-tec boost like with a integra type R for example.
That's because the s2000's v-tec is perfectly tuned and the integra's v-tec shows a dip on the graphics computer before the v-tec kicks in.
That's why the boost is most noticeable on an integra but not better because of it.
That's what i heard from someone that seems to know a lot about it.

To answer the question, yes VTEC does kick in around 6000rpm. Without wanting to explain in detail how it all works, there has to be a number of factors satisfied for VTEC to kick in: 1. Engine warm, 2. Oil pressure, 3. revs.

When VTEC actuates you should be able to hear a change in the engine note. If you are in 1st or 2nd gear you will probably notice the increased torque also. Higher gears the torque is not so noticeable to some people.

VTEC is more noticeable on the F20C s2000's compared to the F22C as the F20C has lower torque up until that point. The addtional displacement of the F22C allows a flatter torque level throughout the rev range. As the torque level is flatter, you don't notice the increase in torque as much when VTEC kicks in.

On some other Hondas the addtional torque VTEC provides is even more noticeable.

In the weekend i'll take the plastic cap off where the airintake is.
Then i will be able to really pinpoint where the v-tec kicks in.
I think the later models engine is a bit quiter and therefore a bit harder to notice.

My 2005 changes personality at 6,000 rpm. The surge is awesome.

This is entirely true. Just because you don't feel the v-tech kick in as you would in a GSR or Prelude or Type-R, doesn't mean that the v-tech is not there. The s2k is just tuned finer than the other cars. Ask any tuner if you are still concerned or worried, they will tell you the same thing, if you look at a stock s2k dyno and a stock Type-R dyno, you will probably notice a dip in the curve of the Type-R graph when v-tech kicks in, and the s2k will be a lot smoother at that point.

Ok, with the good weather today i took my s2000 for a spin with the plastic cap from the airintake off.
I noticed the v-tec a lot more, at least the sound of it.
Thought previously it kicked in just below 7000 rpm but now i can say for sure it's just below 6500 rpm.

I can imagine that some call the v-tec's s2000 a boost from their first impressions but when you have driven it for more then 10000 miles i guess you get a bit used to it and notice it less.

I guess i always expect to much and need to win the lottery to afford a supercar for my next big kick.

A superperformance Brock coup? anyone?

Personally I've never really felt any huge kick as the cam engages (at least before the SC went in). To me, it has always felt like the car just ISN'T running out of breath as most cars do as you get close to or above 7K, it just keeps revving. Same with the VTEC sound some people claim to hear... to me it just sounds like any high revving sportbike engine as it goes through it's range. Naturally, it gets louder and more high pitched the higher you go.
