K24Z vs K24A

Which engine should you choose?

The K24 engine is the "go to" choice for any K-Swap project these days. There are many variants of the the K24 engine. There are "performance" oriented version and "economy" oriented versions. As a rule of thumb. The K24 engines found in the Honda Accord or Honda CRV are of the economy variety, whilst the K24 engines found in the Acura TSX or later Honda Civic Si are of the performance variety. Generally I advise to avoid using any of the "economy" versions of the K-Series engines, unless it is simply as a "engine core" for doing a fully built engine. 

The original K24A2 or JDM K24A is the most commonly swapped version of the K-Series engine. However, the newer and less commonly swapped K24Z version is becoming more popular.

We have focused on the K24Z as the primary supported version of the K24 engine for our K996 and K997 kit. That being said, we do support the K24A engine as well. There are a lot of pros and cons to consider when choosing which engine version of the K24 engine to go with so we will try and help break that down for you.  

The reason we chose the K24Z engine is for these fundamental reasons:

• It is the newest version of the last version of the K24 engine produced, therefore it is the easiest to find in good condition with low mileage
• It has a single exhaust port which makes for turbo kit packaging very compact and efficient while not sacrificing performance
• The engine block has 4 bolts vs 3 bolts for the main engine mount allowing for a more solid / reliable means of engine mounting
• If you truly want push the limits of the K-Series engine - You can still do a traditional Frankenstein head swap such as the K20/K24 Frankenstein 
• It has a higher resolution crank position trigger 60 teeth vs 12 teeth for more precise engine management control

These are just some of the reasons we chose to focus our kit around the K24Z engine, but we are happy to work with you if you want to use the traditional K24A engine instead.
