What is VTEC do? The VTEC (Variable Valve Timing & Lift Electronic Control) system uses separate camshaft profiles for low and high-end performance, and the engine computer selects between profiles. The VTEC system essentially combines low-RPM fuel efficiency and stability with high-RPM performance.
How do I activate VTEC?
Does VTEC add HP?
Like most other variable-valve timing systems, VTEC varies oil pressure to shift between different cam profiles. At higher engine speeds, the cam profile allows greater valve lift, which allows more air into the cylinder. This helps generate more horsepower.
What does VTEC solenoid do?
What does the VTEC solenoid do? Given that VTEC is Honda's fancy name for their variable valve timing system, its job is to advance the timing when extra power is necessary for the upper rev range. The role of the VTEC solenoid is to control the flow of oil to the internal galleries of the overhead camshaft.
Do Hondas still have VTEC?
Today Honda still makes VTEC engines, but given the growth of turbocharging and the fact that other automakers have been using their own forms of variable valve timing for many years, the feeling isn't quite as special.
Related guide for What Is VTEC Do?
What is VTEC on Honda?
VTEC® stands for Variable Valve Timing and Lift Electronic Control, a mechanism used exclusively in Honda engines. VTEC® improves the engine's efficiency without sacrificing power. This is done by matching the air-fuel intake valves and exhaust valves to the engine's speed.
Does VTEC save gas?
VTEC (Variable Valve Timing & Lift Electronic Control) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM.
At what speed does VTEC kick in?
our vtec kicks in at around 4200 to 4500 rpm depending on eninge temp, oil presure and other things. the s2000 vtec kicks in at 6000 rpm.
Is VTEC like a turbo?
Unlike VTEC, a turbocharger doesn't suddenly "kick in" at an exact RPM - it provides varying amounts of boost over a wide RPM range. VTEC is a "digital" device. It is either on or off resulting in a sudden transition and change in engine performance and sound at the engagement point.
Why are Hondas so fast?
In Honda's VTEC engine, the camshaft has two different lobe sizes: Two standard-sized outer lobes and a larger center lobe. As the engine begins to spin more quickly, the center lobe takes over and the valves open sooner and closer later, which results in a sudden burst of speed and better performance.
How much power can a VTEC make?
Vtec is simply the ability to switch between two cam profiles. It doesn't give you power, it doesn't make your powerband larger or broader (at this point), it doesn't allow you to rev higher. It simply is a way to switch between a street profile and a performance profile.
How do I know if my VTEC solenoid is bad?
How much does it cost to replace a VTEC solenoid?
The average cost for a Variable Valve Timing Control Solenoid Replacement is between $198 and $253 but can vary from car to car.
What is so special about Honda VTEC?
The VTEC system uses two camshaft profiles and hydraulically selects between the two. The incredible feature of this technology is that the engine can have the low-speed and high-speed camshafts in the same engine. In fact, the main idea with Honda i-VTEC is to have the maximum engine performance at every RPM range.
Are VTEC engines still made?
Gone is Honda's VTEC variable valve timing and lift. The automaker's camshaft variable timing control (VTC) technology, which is limited to the intake camshaft and is always active, optimizing engine performance and efficiency at any given rpm, replaces the VTEC technology.
Do all Civics have VTEC?

When did Honda introduce VTEC?
The Confidence Needed to Innovate. Honda's new Integra, equipped with the DOHC/VTEC engine, was introduced to the market in April 1989. The VTEC technology drew considerable praise as the world's first valve mechanism capable of simultaneously changing the valve timing and lift on the intake and exhaust sides.
Are VTEC engines reliable?
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.

Can you turbo a R18?
There are 2 different EFR turbochargers to choose from depending on your power/boost goals, as well as price point. For example, if you've installed a Full-Race R18 turbo kit with EFR 6258 and 6 months later you're itching for more power, you can just turn the boost up a little, OR install an EFR 6758 and re-tune…
Which is better i VTEC or VTEC?
