The outstanding VTEC (Variable Valve Timing and Electronic Control) system from Honda gives the EX engine—which has the same 1.7 liters of displacement as the DX and LX engines—a boost.

Does VTEC increase a car’s speed?
Honda created the Variable Valve Timing & Lift Electronic Control (VTEC) technology to improve the overall performance, efficiency, and fun factor of their vehicles. The technology has become a well-known meme as a result of its frequent use in Fast and Furious movies. Few people are aware of the mechanics behind the expression “VTEC just kicked in, yo!” What you need to know about the system is provided here.
A Honda 1.7 engine: interference or not?
The 1.7L interference engine in the 2001–2005 Civic could sustain significant damage if the timing belt snapped.
Which Civics have VTEC?
Three separate Honda Civic models all have one of the two available VTEC-equipped engines that are available for new Honda Civics. The two engines in question are both four-cylinder, lightweight K20 engines, which are well respected for their performance. The small four-cylinder engines developed by the K20 series are possibly the best ever made, including astounding power-to-weight ratios, cleverly simple designs, and incredibly high reliability.
The naturally aspirated K20C2 in the base trims of the Civic sedan and the turbocharged K20C1 in the Civic Type R are the two K20 engines that make use of VTEC in the 2021 Civic. The K20C2 maximizes engine efficiency by using an updated i-VTEC technology for both the intake and exhaust valves. The K20C1 uses VTEC only on the engine’s exhaust side, while a turbocharger forces air into the engine’s intake side at a high pressure. This configuration places a high priority on power and increases the engine’s horsepower and torque without requiring more displacement.
When does the VTEC start working?
In 3-Stage VTEC, the timing and lift of the intake valves are managed by three separate cam profiles. Since there isn’t much room in this version of VTEC because it was built around a SOHC valve head, it can only change how the intake valves open and close. In this application, conventional VTEC performance and low-end VTEC-E fuel economy advantages are combined. In 12-valve mode, which is used between idle and 2500–3000 RPM depending on the load, one intake valve fully opens while the other very minimally does so to avoid fuel from accumulating behind the valve. This 12 Valve mode causes the intake charge to swirl, improving low end performance and fuel economy by increasing combustion efficiency. Depending on the load, one of the VTEC solenoids engages at 3000–5400 RPM, causing the second valve to lock onto the camshaft lobe of the first valve. This technique, also known as 16-valve mode, mimics a typical engine operating mode and enhances the mid-range power curve. Both VTEC solenoids are now engaged at 5500–7000 RPM, causing both intake valves to use the middle portion of the camshaft. Peak power is produced at the highest end of the RPM range by the third lobe, which is optimized for high performance.
In a more recent version of 3-Stage i-VTEC, VTC and PGM-FI were merged to allow the ECU to regulate the whole spectrum of modes and archive higher performance and fuel economy advantages. The Honda CR-Z can continuously transition between low-end and standard modes between 1000 and 2250 rpm and engage high cam mode from 2250 rpm and above on SOHC.
What distinguishes a Honda Civic EX from a Honda Civic LX?
Both the LX and EX come standard with front-wheel drive and an automatic transmission. The 2.0-liter, four-cylinder engine in the 2021 Honda Civic LX produces 158 horsepower. The 1.5L turbo engine in the 2021 Honda Civic EX, meanwhile, has a displacement of and produces 174 horsepower.
What is Honda VTEC?
June 20, 2020. Variable valve-timing system, or VTEC, has been a feature of Honda and Acura vehicles since 1989. The 1991 Acura NSX was the first vehicle in the United States to feature VTEC, which is an acronym for variable valve timing and lift electronic control.
How much does a Honda Civic engine replacement cost?
It can be difficult to decide whether to spend money on pricey auto repairs, yet these circumstances can occasionally arise.
An engine for a Honda Civic can be rebuilt for between $3,000 and $6,000. Nevertheless, the cost mostly relies on the year and particular problem of the car.
During repairing the engine, keep in mind that most automobiles lose 20% of their value after the first year, so you could not get your money’s worth. However, if you don’t care about the vehicle’s value, restoring the engine will be less expensive than buying a new one and will guarantee that it will continue to run for a while.

Honda stopped utilizing VTEC when?
The 2017 Honda Civic Si will include a turbocharged engine, which is a first for the trim, and will go on sale next month for around $20,000. The 1.5-liter engine has the same 205 horsepower as the old 2.4-liter four with naturally aspirated gas. However, compared to the normally aspirated engine, torque is up 18 lb-ft to 192. The Civic Si should be enjoyable to drive because it has more power accessible lower in the rpm range and a standard six-speed manual transmission.
A sport-tuned suspension with firmer springs and antiroll bars helps to improve car control. Honda claims the new Si is substantially lighter than the previous version (without providing details). A two-mode adaptive damper system (sport and normal), a limited-slip differential, and larger 12.3-inch front brake rotors are all included as standard equipment.
The coupe and sedan both feature subdued design (at least compared to the Type R). The Si gets wider side vents at the back, black trim on the front fascia, 18-inch, 10-spoke wheels, and center-exit exhaust. No flashy body kits or extraneous wings are present.
It will be interesting to see how the 2017 Civic Si stacks up against rivals like the Ford Focus ST, Subaru Impreza WRX, and Volkswagen Golf GTI. With starting costs in the mid-$20,000 range and greater power than the Si, the competition may damage Honda’s new Si. Alternately, the Si could triumph despite lacking VTEC. As soon as we can get behind the wheel, we’ll let you know.
What VTEC engine is the best?
The B18C6 is one of the best-rated Honda VTEC engines. This 1.8L 4-cylinder engine was installed in Honda Integra and Acura Integra Type R models sold worldwide from 1999 to 2001. For a car that was so light, its 195 horsepower and 130 pound-feet of torque were excellent. Additionally, it had a redline of 8400 RPM, while VTEC began to operate at 5700 RPM.
Because it was simple to alter and had that distinctive DOHC VTEC sound when you approached the VTEC engagement point, the B18C platform rose to great popularity. This results in a lot of power in the higher RPM ranges, making the cars they are in feel sportier and more enjoyable.
The B18C is still recognized as one of the best VTEC motors ever made, and it continues to be in high demand all over the world. If you’re looking for an excellent, low-mileage B18C, be prepared to pay more.
Whether a timing belt or chain is present on a 2003 Honda Civic.
All 2005 Honda Civics have a timing belt and interference engine, with the exception of the Si and Hybrid variants. The Si and Hybrid models are interference and have a timing chain. Check out the information in the table below.
When should a Honda Civic’s timing belt be changed?
To replace your timing belt, however, you should generally wait somewhere between 60,000 and 100,000 miles.
