Honda K20 vs K24 – Detail Comparison

In the world of automobiles, Honda is one of the giants that has been ruling this industry for years. Honda K20 and K24 both have been favorites among many car enthusiasts. However, a common question that bugs many is, “Honda K20 vs K24: Their ultimate differences?”

The K24 offers more low-end torque than the K20 but higher deck height 9.1 inch.

The K series has some of the most significant differences like the total capacity, overall horsepower, and even the structural designs. Therefore, you must be aware of these differences before picking one of these engines. In some cases, K20 performance overruns the K24, and there are times when K24 takes the lead. 

So, here in this blog, our automotive experts will let you know all the ins and outs of these two versions of the Honda K series and how they possibly differ.

The Journey of Honda K Series

When purchasing a motor engine, you would want to know its background. The previous model that the K series replaced was the Honda B series.

The Honda B series was quite famous during the 1990s but were detected with flaws and drawbacks, which were creating issues for many car owners.

That’s when Honda launched the first version of the K series, the “K20”. However, some of the features of the Honda B series were precisely the same in the K series. This is why many even think K20 is the updated version of the B series.

For instance, the displacement was updated from 1.6 to 2.0L; the torque was modified to clockwise rotation. The rotation was also modified in the K series; the rotation was anticlockwise in the B series. Moreover, despite having the same 4 cylinders, the engine arrangements were slightly different.

However, both Honda K20 and K24 became two individuals with specific characteristics and unique performances that soon became the favorites of many automobile owners.

Honda K20 vs K24: The Most Significant Differences

The Honda K series is more like the B series with a compact design. Moreover, the models come with four cylinders and have great potential in terms of performance. But there is some significant difference between K20 and K24, which you will know as you go through this blog.

Total Capacity

The first difference you will see when you keep the two engines for comparison is that the K20 has a total 2.0L displacement. In comparison, K24 comes with 2.4L displacement. So, in terms of capacity, K24 plays the first-hand.


Both the dimensions of K20 and K24 are pretty much different. When you compare these two versions, you will notice that the first model is kind of square in shape. Moreover, in K20, the displacement engine dimensions are around 86mm bore and 86mm stroke. At the same time, the K24 has an 87mm bore and a 99mm stroke.


If you’re working onthe K24 and K20 engines, you should definitely consider the total power the engines will deliver. However, the K20 engine takes the lead here as it can quickly provide 221 Hp, whereas K24 can only exert 160 Hp, which isn’t sufficient to provide the required performance.

Torque is another essential factor you must consider as the overall engine performance depends significantly on the spinning. In this case, Honda K24 takes the upper hand as it has a comparatively more snipping effect than K20 with 6500 RPM and 6100 RPM, respectively.


K20 is more common in Civic, RSX, Integra, Stream, and Accord vehicles. K24 is primarily implemented in CR-V, TSX, Odyssey, Accord, and Element.

Therefore, next time someone asks, “Is K20 better than K24?” The answer entirely depends on which purpose you’re using.

The Basic Similarities Between K20 and K24

Similar is quite evident for these two remarkable versions of Honda as they are from the same series.

If you inspect carefully, you’ll notice:

  • The deck heights in both models are above 200mm. The sizes may vary, but their overall appearance and design are pretty much the same.
  • Moreover, K20 and K24 get along well with VTEC and i-VTEC system control for better performance.
  • They also have four-stroke and four cylinders engine motors, along with turbochargers and hot-rodders that perform pretty much the same.
  • You may indeed find some operating system differences, but they are not very notable. So, we can say that both K20 and K24 have the same operating system and installation process.

Which Is Better: Honda K20 or K24?

Each of the models has its perks and drawbacks. So, which one’s better depends on where and for what purpose you use them.

For instance, if you own a large and heavy-duty car, K24 should always be your choice as it can easily take on heavy-duty tasks. On the contrary, if you’re choosing an engine for a small car, you must choose the K20 as it’s more compatible and can operate with enhanced performance.

Similarly, if you’re looking for an engine that provides better energy (horsepower), you have to pick the K20 since it provides more horsepower than K24.

The structure preferences also play a significant role when choosing your desired K series engine. If you prefer a square shape, then the K20 gets ahead. However, if you’re okay with any type of shape and want something significant, the K24 is the better option.

In contrast, if you want your car engine to be the best in all ways possible, you must first know the differences between the engines and how durable they will be in the future.

Bottom Line

Honda K20 vs K24, which one to pick? It entirely depends on your usage and the features you want these K series engines to provide. Therefore, we recommend you go through the differences before purchasing. This will clear out all the uncertainties and give you a categorical justification for picking the best one.
