VVT-i (Variable Valve Timing with intelligence) is a similar system developed by Toyota and has several variants among which VVTL-i (Variable Valve Timing and Lift intelligent system) is analogous to VTEC.
Subsequently, Is VTEC bad for engine?
Not hitting vtec ATLEAST once a day can cause both problems to the driver, and the car. Without hitting vtec daily- the driver can develop a “light” foot. The car also suffers because it enjoys crossing over the line at 6000 RPM and making that nice growling noise.
then, Which is better i VTEC or VTEC?
Intelligent Variable Timing (and lift) Electronically Controlled (iVTEC), is a system that combines VTEC and VTC into one unit. The VTEC part of the system allows valve overlap to be adjusted at any moment, resulting in much greater efficiency and slightly better performance. …
Thereof Which is better VVTi or VTEC? And a Honda engineer came up with a solution or as we all know it better ‘i-VTEC‘. It is Variable Valve Timing and Lift Electronic Control with intelligence. … The VVTi only alters the timing while i-VTEC alters the timing as well as lift of the valves. Also, the VVTi technology works only on the intake valve.
Is VTEC only for Honda?
So yes, VTEC is Honda only and yes, there are other technologies that achieve the same, or very similar, goals.

Is it good to hit VTEC?
In a straight line, ‘hitting VTEC’ often results in noticeably more power and a satisfying sound as the cam profiles shift. … The clip below answers that age-old question and to our surprise, yes, you can hit VTEC in reverse, not that doing so serves any real purpose.
Can you feel VTEC kick?
Registered. Yes I can, its at 4500 rpm, under that the engine is basically silent, then it roars up to redline, you can see the spedometer needle actually goes faster from 50-60mph then it does from 40-50 because the higher rpms in second gear.
Is DOHC better than VTEC?
Just wondering what are the main differences between DOHC vtec and SOHC i-vtec. Essentially speaking the biggest difference is the number of camshafts the engines have. DOHC engines are designed to rev higher, have peakier power outputs and PERHAPS high horsepower application.
How much does a VTEC engine cost?
The JDM Honda B16A VTEC Engine Transmission Civic SiR B16A2 engine price for Honda Civic is around $ 2500.00.
Is DOHC VTEC?
The original VTEC system was introduced in Honda’s DOHC (Dual OverHead Camshaft) engines in the 1989 Honda Integra XSi and was first available in the United States in the 1991 Acura NSX. … The i-VTEC® system combines the original VTEC with Honda’s VTC (Variable Timing Control).
Is a VTEC engine good?
Honda claims that there has never been a warranty claim against their VTEC systems – as in, the solenoids and variable valve/timing system is quite reliable. This isn’t at all to say that these engines don’t fail – of course they do – however they have a very good track record for reliability if maintained correctly.
Does Nissan have VTEC?
NVTCS equipped Nissan engines do not have as high of engine speeds as VTEC equipped engines so NVTCS is simpler, quieter, and requires no special maintenance.
Who invented VVTi?
VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 5-valve per cylinder 4A-GE engine.
Are Honda VTEC engines good?
Honda claims that there has never been a warranty claim against their VTEC systems – as in, the solenoids and variable valve/timing system is quite reliable. This isn’t at all to say that these engines don’t fail – of course they do – however they have a very good track record for reliability if maintained correctly.
At what speed does VTEC kick in?
It depends on the engine. Most Hondas had vtec crossover in the low to mid 5000rpm range. You had 2 camshaft profiles, 1 optimized for low-mid rpm driveability and fuel economy and another for mid-high rpm power.
How do I know if my VTEC is working?
SO MAKE SURE YOUR CAR IS WARMED UP AND YOU HAVE A SUFFICENT OIL LEVEL. When the wires touch you should definately feel a differance, well, that is if your vtec is working.
Does VTEC burn oil?
The answer is yes, you will. Its a Honda, they generally consume oil in vtec.
Why is vtec so good?
The VTEC system essentially combines low-RPM fuel efficiency and stability with high-RPM performance. And the transition occurs seamlessly, allowing for smooth performance across the entire powerband. The switching operation between the two cam lobes is controlled by the engine computer.
Does Honda make a V8?

Does vtec have a sound?
vtec is allowing more air and gas to enter into the combustion chamber, creating a bigger bang. You hear this. Usually, the “noise” is slightly higher pitched (when in vtec), if you have a raspy exhaust, it is only going to sound raspier.
Are DOHC engines good?
A DOHC, four valves per cylinder configuration allows better airflow at high engine speeds, resulting in better top end power. DOHC engines also allow the spark plug to be placed right in the middle of the combustion chamber which in turn promotes efficient combustion.
Why does Honda still use SOHC?
The biggest reason to use them is because DOHC engines are more expensive to produce (which price would get pushed back onto the consumer), there are more moving parts in them (which means they will fail sooner), and they can still do VTEC in either version.
How does SOHC VTEC work?
In the SOHC VTEC-E implementation, only one intake cam-lobe is implemented on the camshaft. … This promotes a swirl action during the intake cycle. VTEC is used to activate the inactive valve, making the engine work in 16-valve mode in more demanding and higher rpm conditions.
