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.
Subsequently, How much HP does VTEC give?
Its four-cylinder B16A produced 160 horsepower from just 1.6 liters—100 horsepower per liter—an unheard-of power density for automotive engines.
then, 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.
Thereof 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).
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.

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.
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.
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.
Why is VTEC famous?
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.
Can you put a VTEC in any car?
yes, it will run just fine. though if you want vtec to work you will need to wire it up either straight to the ecu through the firewall (plug underneath the battery box, almost directly at the ecu) or through the shock towers to make it look OEM.
Who makes Honda engines?
Honda produces small engines at 5 production facilities worldwide. Our production capacity is well over 7 million units. Engines for the U.S. market are primarily sourced from the U.S., Japan, and Thailand.

What is the fastest VTEC motor?
High-rpm flogging is not required but makes for storming good fun as the 2.0L turbo 4-cyl. pounds out 306 hp before reaching the 7,000-rpm redline. With a specific output of 153 hp/L, this VTEC engine is the most powerful street-legal Honda ever to reach America.
What’s the difference between VTEC and 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.
Is the VTEC a good engine?
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.
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.
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.
Is VTEC 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.
What is more reliable SOHC or DOHC?
Compared to SOHC designs, DOHC engines have a more complex chain or belt drive system. This decreases overall reliability and adds to maintenance expense. As with SOHC designs, DOHC engine height is increased and overall weight also tends to be higher.
What cars have DOHC engine?
Most DOHC engines have four valves per cylinder, however DOHC engines with two valves per cylinder include the Alfa Romeo Twin Cam engine, the Jaguar XK6 engine, the early Ford I4 DOHC engine and the Lotus Ford Twin Cam engine. The camshaft usually operates the valves directly via a bucket tappet.
Are SOHC engines good?
SOHC is more fuel-efficient since its power consumption is low. The spark plugs are not located at the center of the cylinder. They are not strategically located, thus hindering the performance of the SOHC engine. SOHC has a better low-end torque.
