There are two different types of K24Z engines, the K24Z3 and the K24Z7. Both engines are 2.4 liter I4 DOHC engines, but there are some differences between them. The K24Z3 engine is found in the Honda Accord while the K24Z7 engine is found in the Honda CR-V.

The K24Z3 engine has a power output of 185 hp while the K24Z7 engine has a power output of 190 hp. The compression ratio on the K24Z3 is 11:1 while on the K24Z7 it’s 10:1. The bore x stroke for the K24Z3 is 87mm x 99mm and for the K24Z7 it’s 86mm x 96mm.

There are many differences between the K24Z3 and K24Z7 engines.

The most notable difference is that the K24Z7 is a high-performance engine, while the K24Z3 is not. Other differences include the fact that the K24Z7 has more torque and power than the K24Z3, and it also has a higher redline.

Additionally, the K24Z7 has different intake and exhaust manifolds than the K24Z3, as well as different pistons and connecting rods. Finally, the ECU tune is different on the two engines, with the K24Z7 being tuned for more performance.

The Differences Between Honda K-Series Engines

Is the K24Z3 a Good Engine?

The K24Z3 engine is a 2.4L inline-four gasoline engine that was produced by Honda from 2006 to 2013. It was used in the eighth-generation Honda Accord (2003-2007) and ninth-generation Honda Accord (2008-2012). The K24Z3 engine is an evolution of the K20A2 engine used in the previous generation Accord.

The biggest difference between the K20A2 and K24Z3 engines is the stroke. The K24Z3 has a longer stroke than the K20A2, which increases displacement from 2.0L to 2.4L. This increase in displacement results in more torque and power, without sacrificing fuel economy.

In addition to the increased displacement, the K24Z3 also features a higher compression ratio (11:1 vs 10:1), revised intake and exhaust ports, sodium-filled valves, forged connecting rods, and a balance shaft delete kit. These changes help to improve performance and durability. Overall, the K24Z3 is a great engine that offers increased power and torque over its predecessor while still maintaining excellent fuel economy.

If you’re looking for a reliable and powerful engine for your Accord, then the K24Z3 is definitely worth considering.

What Car Does the K24Z7 Come In?

The K24Z7 engine is found in the 8th generation Honda Accord (2013-2017). It is a 2.4 liter, 4-cylinder engine that produces 185 horsepower and 181 lb-ft of torque. This engine is mated to a 6-speed manual or CVT transmission.

Does K24Z7 Have Vtec?

The short answer is yes, the K24Z7 does have VTEC. However, there is a bit more to it than that. Let’s take a closer look.

VTEC, or Variable Valve Timing and Lift Electronic Control, is a system found on many Honda engines that allows for increased performance by altering valve timing and lift. The K24Z7 engine uses what is known as “i-VTEC” which adds variable timing to the intake camshaft in addition to the traditional VTEC system found on other Honda engines. The result is an engine that produces more power and torque than a non-VTEC engine while still maintaining excellent fuel economy.

So if you’re looking for a little extra power from your Honda Accord or CR-V, be sure to check out models with the K24Z7 engine – they just might have what you’re looking for!

K24Z3 Vs K24Z7


K24Z3 Vs K24A2

If you’re looking to compare the K24Z3 vs K24A2 engines, there are a few key things to keep in mind. The K24Z3 is a 2.4L I4 engine that was introduced in the 2012 Honda Civic Si. It features VTEC+VTC and makes 205 hp @ 7000 rpm and 174 lb-ft @ 4400 rpm.

The K24A2 is a 2.4L I4 engine that was introduced in the 2006 Honda CR-V. It also features VTEC but makes slightly less power at 160 hp @ 5800 rpm and 161 lb-ft @ 4200 rpm. When it comes to performance, the K24Z3 definitely has an edge over the K24A2.

However, remember that the Civic Si is a performance-oriented vehicle while the CR-V is more of a utility vehicle. So if you’re looking for an engine upgrade for your CR-V, the K24A2 might be a better option since it’s designed for that type of vehicle.

Is the K24Z7 a Good Engine?

The K24Z7 engine is a 2.4-liter inline 4-cylinder engine that was produced by Honda from 2006 to 2011. This engine was used in the 8th generation Honda Civic Si and in the 9th generation Honda Accord. The K24Z7 engine produces 201 horsepower at 7000 rpm and 170 lb-ft of torque at 4400 rpm.

This engine is capable of revving up to 8000 rpm. The redline for this engine is 7600 rpm. The compression ratio for this engine is 11:1.

This engine has been praised for its high power output, fuel efficiency, and reliability. Many people consider the K24Z7 to be one of the best engines that Honda has ever produced.


If you’re looking at the K24Z3 and the K24Z7, you might be wondering what the difference is. The answer is that the K24Z7 has a higher redline and more aggressive cams. Other than that, they’re pretty much the same engine.

So if you’re looking for more power, go with the K24Z7.
