How often do you VTEC your engine

I Vtec it almost every time I take her out for the day. As for rev limiter, I try to avoid that. I'd say.... once every month, maybe twice since I usually drive my car every friday-sunday.

Doubtful Vtec hurts the motor. Not sure what the rev limiter kicking in might do though in the long run.
 
Geez, if youre not gonna Vtec your NSX (or any other Honda), why get a model with Vtec in it?

Vtec --> Harmfull --> No way

Ever noticed the red part on the rev.counter? rtm
 
LoL, the odor could be from many sources. Can you be a little more descriptive? Oil burning? Smell from the catch? Smell from inside the cab? Smell from your shorts after hitting Vtec coming out of a corner? :tongue: lol

Seriously though, it won't hurt. Smell could be anything. We need more details.
 
The Engine is very robust and can tolerate most you throw at it, from heresay you will require more seals doing so. I personaly only take it up to 6-7k few times month when weather permits to keep the gears lubbed and functional.
 
Once a day or so I take it to redline.

I had the same question back when I bought my Integra Type-R. How much I could redline it, how much does it hurt it, etc. The sales guy(who was actually a really smart guy with direct ties to Honda in Japan) said redline it to your hearts content. It WILL NOT hurt a thing. It was designed to do that redline safely without stressing the engine.

When I tracked my old ITR, I would keep it in VTEC for 30 minutes at a time at track events. A few hundred miles of almost all VTEC. Doesn't hurt a thing.

I have heared similar about integras and oil leaks, might not hurt anything but does promote premature wear.

If your redlining an S2000 2000/01 and you take it to 9k and oops 4th spark plug stop allowing oil to feed and the engine starts nocking.lol

Glad we driving an NSX:biggrin:
 
I VTEC and redline the car practically every day I drive it. Don't drive it everyday, but when I do, I like the feel it gives. Not doing it twenty times a day though because normal traffic usually won't allow for it.
 
Not trying to be a wise ass or anything but why would those two model years S2k's have an oil feed issue because of the 4th spark plug???

8 ENGINE FAILURE IN #4 CYLINDER
A small number of owners, approximately three dozen are known, report major engine failure due to the #4 Cylinder Scoring.

One of the frustrating things about this major failure is how some customer’s are treated when it does happen. For some it has become necessary to prove they were not a fault! For others, repairs were painless.

If you hear an engine noise that is very distinct and sounds like tapping. The engine will not last long after you hear the noise. You can hear the noise in the cabin, but it best noticed with the hood up, the noise will come from the bad cylinder area. If your engine makes a bad tapping sound, Honda should pull the plugs and see if all are a nice gray white or one shows black from incomplete combustion. If a plug is blackened, they should put a scope inside the spark plug holes and see if they can see some cylinder damage.

The cylinder wall scuff problem in Honda S2000 typically has shown up in the #4 cylinder. Naturally, Honda has not shared with the public what is causing the problem, assuming they know. But it’s likely a piston / cylinder / lube / cooling related thing. Factors such as metallurgy, tribology, material compatibility may be the issue. Why only number 4? Something is different about what that hole experiences compared to the others.

If you're too low on oil, the first thing to give in is classically the rod bearings, followed by the mains. The top end and pistons/cylinder walls fail from the lack of lubrication much later than pressure fed bottom end bearings. In a way the bottom end bearings act like a fuse for the other stuff.

If the engine failure is due to over revving, the top end would tend to get hurt - bent valves and such. But the bottom end may survive. It certainly won't develop the cylinder wall scuff problem from an over rev.

BTW, as of March 2003 there have been at least two known engine failures which has the new 4-hole oil banjo bolt installed (which some owners felt would cure the problem).
 
The original question was about VTEC. Since VTEC engagement occurs at 5,800 RPM, I engage it every time I drive my NSX. I don't redline it that often, but I do often. I used to redline my RX4, my RX7, my Jaguar 4.0 S-type, etc. Hell I redline my Ridgeline occasionally.

I can't believe anyone here is afraid redlining the car regularly will hurt it. What good are sports cars if they can't be rev'd?

90% of the issue is owners not maintaining their oil level. I have an 02 S2000 also that only has the one oil squiter according to the engine # on the block and have never had a problem and I drive the car like any other Honda should be driven, in VTEC where it makes the most power.

Over-rev and the oil squiter issue are 2 different things. With the S2000's tight gearbox some owners have downshifted into the wrong gear and oops the crank just split your block in half and all your valves are all bent now that would suck!

I have not heard any issues with the NSX but Ive only had it for a month or so now.
 
Only after I let my engine warm up for at least 20 minutes....then it depends upon the traffic. Freeway onramps are a great place for engaging Vtec:biggrin:
 
I V-tak from 6k to 9k all the time. I even v-tak when I use the restroom. It'll be fine. V-tak pulls hard on a S2000 it must be nice on a NSX. The only other car I drove that you can really feel the pull like the S2000 is on a Celica GTS. You can feel it on that car too. Although I believe its only like 6K to 7k.

As long as you keep the fluids & spark plugs in top condition you'll be fine. ONly problem I can think or is you'll run into leaks with gaskets because its more stress on the engine.


How often do you VTEC or red line your engine? If do this too often would it hurt the engine?
 
I can smell some odor after VTEC the engine, is this normal?

you probably have a spool valve gasket leak ( vtec ).

when you hit or when ou drive the car in general in the high rpm range, things start leaking.

take it to your local nsx guru and get them to give the car a once over.

oil leaks are very easy to find. isolating the leak is a bit tricky but nothing that cant be managed with with a dye in the oil.

if you have a Honda with vtec... the general rule put forth by Honda is is that you vtec is prerequsit to shifting. :smile:

happy motoring, vtecing.

Yeh this was according to the author not my words. I see what your saying, however UK Honda has put this on recall why is not USA getting the recall?
 
V-tak pulls hard on a S2000 it must be nice on a NSX. .

Actually it's really really smooth transition when Vtec kicks in on the nsx. Doesn't do that massive pull the way the S2k does at all. From what I hear/read, the "exaggerated" vtec feel in cars like the S2k is due to detuning below Vtec from the factory. Gives you that "Vtec power" feel when it kicks in. I could be wrong though.....

Yea the VTEC actually doesn't give the NSX a pull, we get pulls below VTEC actually :smile:

the last good thing the D.O.T. has done was not put speed limits on on-ramps, but lets keep this on the DL. if you say it outloud they'll be up tomorrow!

The warm up is key! My S2000 has a temperature limited rev limiter. Under operating temp, the car will not rev above ~4500rpm. Once warm you can take it to 9000. I have not found this with my '91 NSX.

I just do not run it hard until warm. Then I give it what it can take.
