In the automotive world, there is a lot of talk about Vtec killers. But what exactly is a Vtec killer? Well, it’s basically a car that can outperform a Honda with a Vtec engine.

There are a few different ways that this can be done, but the most common way is by having more power. Now, this doesn’t necessarily mean that the Vtec killer will always beat the Honda in a race, but it will usually come out on top in terms of acceleration and top speed.

Vtec Killer is a device that allows you to use a non-vtec engine in a vtec car. This can be useful if you want to use a cheaper, less powerful engine in your car. It can also be used to increase the power of your engine by using a more powerful one.

VTEC Killer: Pros, Cons & Gain’s Expectations

What is Vtec Killer

If you’re a car enthusiast, you’ve probably heard of VTEC. But what is VTEC and how does it work? And what is a VTEC killer?

VTEC stands for Variable Valve Timing and Lift Electronic Control. It’s a system that was developed by Honda to improve engine performance. VTEC allows the engine to switch between two different camshaft profiles.

One profile is designed for low-rpm operation, while the other is designed for high-rpm operation. At low rpm, the engine runs on the low-lift/low-duration cam profile for improved fuel economy. When the engine reaches a certain rpm (usually around 4500-5000), it switches to the high-lift/high-duration cam profile for increased power output.

A VTEC killer is an aftermarket device that disables the VTEC system. This can be done in one of two ways: by physically disconnecting the VTEC solenoid, or by tricking the ECU into thinking that the engine is always operating at low rpm (even when it’s not). There are a few reasons why someone might want to disable their vehicle’s VTEC system.

The most common reason is that they’ve swapped out their stock engine for a larger, more powerful aftermarket engine. In this case, they’ll usually also install larger camshafts with different lift and duration profiles than what came in stock on their vehicle. Since these aftermarket camshafts don’t have provision for switching between low and high lift/duration profiles like the stock ones do, there’s no need for the VTEC system to be active – hence why people will disable it using aVTec killer.

Another reason why someone might want to use aVTec killer is if they’re having issues with their vehicle’s emissions control system. Specifically, they might be getting “check engine” lights due to the triggering of one or more of their vehicle’s emission monitors – such as those related to catalytic converter efficiency or fuel evaporation rates. In some cases, simply disabling the VTEC system will cause these emission monitors (s) to reset and go back into compliance mode – thus avoiding costly repairs or replacement of parts.

So there you have it – that’s whatVTec killers are and why people use them.

Who Created Vtec Killer

Vtec Killer is a performance engine modification created by Japanese tuner HKS. The Vtec Killer kit includes an ECU chip, modified intake and exhaust manifold, and larger injectors. When installed on a Honda engine, the Vtec Killer allows the engine to produce more power without activating the Vtec system.

This results in increased performance at lower RPMs, making the car more responsive and fun to drive.

Is Vtec Killer Legal

Vtec Killer is a legal tuning option for Honda vehicles in the United States. Vtec Killer is an aftermarket camshaft that allows the engine to run without the use of Honda’s Vtec system. This results in increased power and torque throughout the entire rpm range.

The tradeoff is that fuel economy will suffer and emissions will increase.

Vtec Killer K20A3

The K20A3 engine is a 2.0L DOHC inline-four engine produced by Honda. It was first introduced in the 2002 Acura RSX and was also used in the 2006-2011 Honda Civic Si. The K20A3 produces 200 hp at 7,000 rpm and 140 lb⋅ft of torque at 5,800 rpm.

The Vtec Killer tag comes from the fact that this engine can be modified to produce significantly more power than a stock Honda K20A or K24A engine while still retaining excellent reliability. When compared to other engines in its class, the K20A3 has often been praised for its high power output and low cost of ownership. There are several ways to increase the power output of a K20A3 engine.

One popular method is to install a larger turbocharger or supercharger. This will typically result in an increase of around 50-60hp over the stock power figure. Other methods include porting and polishing the cylinder head and installing aftermarket camshafts.

These modifications will usually result in an additional 20-30hp over-stock figures.


A Vtec Killer is a device that allows a non-vtec engine to run a vtec head. This means that you can have the benefits of vtec without having to buy a vtec engine.
