Vtec?

[Dabbalz]

honda vtec is controlled by oil pressure, it allows a pin to be inserted into the larger cam lobes so with larger cam lobes, the engine gets in more air and gets it out quicker, speeding up the combustion process.

they have vvt in quite a few cars, alfaromeo 145/146 and 156 its called the cam variator and does the same as our vvt, it just advances and retards the ignition timing, same as toyota vvt (not to be confused with vvtl - which is toyotas version of vtec ...the l meaning lift...they also use a larger cam lobe ) .... completely different to honda vtec

Thank god for that, someone giving a true answer to the question! This is exactly what i was going to say.
I had the Celica VVTi and wanted the VVTL-i when it came out, the Lift control engines were the result of a team up with Yamaha.

The Vtec on my honda VFR800 works different, it operates as an 8valve engine below 7000rpm for more torque but then as you hit 7000rpm it turns into a 16valve for higher power up to the 12000rpm limit.

Hope people stop commenting about it being like a turbo etc or even VVT been the same as Vtec as yes Vtec has VVT but it's the low & high lift cam lobes that are the main feature.

Variable valve Timing & Lift Electronic Control (VTEC)
Variable Valve Timing & Lift - Intelligence (VVTL-i)

This is just for info, not to p**s on your parade as I think v-tecs have their place .

Nissan engines:
SR16VE - 173hp @ 7800rpm / 119lb torque @ 7200rpm
SR16VE N1 - 197hp @ 7800rpm / 134lb torque @ 7600rpm

What cars did those come in.

It's not pissing on my parade. I'm impressed. I know there are a few engines that match the torque output. But in general, Honda engines make decent torque.
The problem is, people compare a 160bhp 1.6 vtec to things like redtops, the 2.0 16valve in ibizas, golfs etc, because the power output is similar, then complain how low the torque is.

Instead of praising the Honda for making a lot more power per cc, they slate it for not making the torque of a bigger cc engine.

I also think vtec has it's place. Unfortunately for me (and I've owned a load of hondas) that the ep3 is where it all started to go wrong. The b16/b18 engines are a couple of the best engines available for their time.

I was impressed by my mates civic , couldnt believe how quick it was for a 1.8 n/a engine

So has the pinto engine, and your point is?


It's like bad sex all that wait and your faced with triangle nipples

The pinto isn't overrated either though.

My point is, that when your turbo seat wasnt even an afterthought to vw, Honda had some of the best engines/technology on the Market. How you can say that's overrated is beyond me.

The current I-vtec engines make plenty more power than there other na counterparts (and I don't even like the newer engine) so how can you say it's overrated?

Because it's slower than all the 2.0 turbo cars on the Market. Shocker. A 2.0 na car is slower than it's turbo'd counterpart. That must make it overrated then

My mate reckons you are all wrong, he says you are all hating on it because it's Honda and everyone on here drives Seats. The guy knows what he is talking about and I believe what he has to say, so I think I am going to go ahead and see what he can do trying to get it to fit. Not saying I don't believe advice on here, it's just that you are all going to be vey bias against Honda.

You are having a laugh right?

is 106 lb/ft any good??? lol i not a massive v-tech fan i think its a very good system and does work BUT it is mainly noise you cant compare the torque figures produced to any turbo or super charged car good old forced induction wins every time

*cheeper to get good gains from
*better gains to be had
*higher figures to be seen
*and they sound so much nicer with the turbo whistling away!

moral of the story turbo charge cars are much more fun and better end of close thread bla bla bla

i thought i saw your name on a loaf of hovis comes to mind


try it please i'll tell you what ill go and get a mate who build these engines for a living to see if he agrees i worked for honda for 3 years doing all sorts and in that time managed to learn a thing or two have you not watched the youtube vid???????

your mate is a spoon were not hating on him atall most of us are saying we like the v-tech i like v-tech i just prefer turbos

Those are power figures not torque. Although the mivec engine does have a slightly better torque output. (it uses mivec to achieve it though, which is similar to vtec)

And rotary engines are 2.6 everywhere in the real world. Theyre only 1.3s on the internet

Good luck with that.

Will be good to see the new camshafts you need to have made with the second high lift lobes, the machined cylinder head casting you'll need to produce to fit the cams, along with the different cam/valve interfaces (vtec uses rocker arms on some setups), the oil channels you'll need to run to the middle rocker arm (high lift VTEC one) and of course the relevant solenoid/ECU interface to run it.

Seriously, it'd be easier to turbo a 1.8 VTEC engine and drop that in instead. And would give much better results!

there still 1.3 engines mate just equivalent to a 2.6 and twice as juicy
