K24 Engine FAQs

1. What vehicles can the K24 engine be swapped into?

The K24 engine is commonly swapped into various Honda models, including the Civic, Accord, CR-V, Element, and even the Acura RSX. Enthusiasts often choose the K24 engine because of its compatibility with many Honda vehicles, as well as its performance potential for swaps and builds.

2. How much does a K24 engine cost?

The cost of a K24 engine can vary greatly depending on factors such as the engine’s condition (new or used), the specific model, and whether it includes additional parts like the transmission or ECU. On average:

• Used K24 engines: $1,000 to $3,000
• New or rebuilt K24 engines: $3,000 to $5,000 or more

Additional parts like the transmission, wiring harness, and ECU may also be included in engine packages, which can increase the overall price.

3. Can I turbocharge a K24 engine?

Yes, the K24 engine can be turbocharged. It is one of the most popular choices for turbocharging because of its strong internals, good airflow characteristics, and tuning potential. However, adding a turbocharger requires supporting modifications, such as a stronger fuel system, better cooling, and upgraded internals (pistons, rods) to handle the increased boost and power.

4. What is the difference between K20 and K24 engines?

The K24 engine is larger in displacement (2.4 liters) compared to the K20 (2.0 liters). The K24 has a longer stroke, which provides more low-end torque, while the K20 has a shorter stroke and revs higher, making it more ideal for high-revving performance. The K24 generally has better torque output and is preferred for engine swaps when more low-end power is desired.

5. Are there any known issues with the K24 engine?

The K24 is a reliable engine, but like any engine, it is not immune to issues. Common problems include:

• Oil consumption: Some K24 engines, especially earlier models, may experience oil burning.
• Timing chain tensioner failure: In some cases, the timing chain tensioner can fail, causing a rattling sound or engine damage if left unchecked.
• VTEC solenoid failure: Over time, the VTEC solenoid can malfunction, leading to issues with the VTEC system.

Regular maintenance and care can mitigate these issues.

6. How much power can a K24 engine handle?

The K24 engine is capable of handling significant power, especially when modified. Stock K24 engines can safely handle up to 250-300 horsepower without major internal upgrades. With a turbocharger or supercharger and supporting modifications (such as stronger pistons, rods, and better cooling), K24 engines can produce upwards of 500 horsepower.

7. How long do K24 engines last?

With proper maintenance, a K24 engine can last over 200,000 miles. Regular oil changes, timely maintenance, and addressing any issues as they arise can significantly extend the lifespan of the engine.
