K24A Engine Mods & Tuning
There are many modifications and upgrades available for the K24A engine, ranging from intake and exhaust modifications to fuel and ignition system upgrades. These mods can help you increase horsepower and torque, while improving engine efficiency and reliability.
1. Intake Manifold:
Replacing the factory intake manifold with a modified one can help you increase air flow and improve engine performance. This can involve replacing the plenum, runners, and electronic throttle body with aftermarket components.
Swapping out the factory intake and exhaust camshafts with higher lift and duration aftermarket cams can increase engine power. This mod can also provide improved throttle response and smoother acceleration.
3. Exhaust System:
Installing a high-flow exhaust system can help improve engine output and reduce back pressure, resulting in more horsepower and torque. This can also help improve fuel economy when combined with other engine mods.
For more serious power gains, you can opt for a built motor. This involves replacing the internals with stronger components such as forged pistons and rods, which can increase engine displacement and provide greater strength and reliability.
1. Turbocharger/Supercharger Kits:
These kits are designed to increase the boost pressure of the K24, resulting in increased power and torque. Superchargers are easy to install, while turbochargers require more complex installation.
Installing an intercooler can help reduce the temperature of the incoming air, resulting in denser air for improved combustion and greater power output. This is a must-have mod for any forced induction setup.
3. Fuel System:
Forced induction setups generally require an upgraded fuel system to meet the increased demand for fuel. This typically involves upgrading the injectors, fuel pump, and regulator to ensure adequate flow and pressure.
No matter what mods you choose, it’s important that they are properly tuned to maximize engine performance. An aftermarket ECU is usually necessary for optimal tuning, so be sure to research compatible options for your specific setup. With the right modifications and tuning, you can unlock the potential of the K series engine and enjoy improved performance.
Common Problems with the Honda K24
The common problems associated with the Honda K24A engine include front main oil seal leak, timing chain tensioner, exhaust or intake camshaft wear, and oil pressure issues.
Front Main Oil Seal Leak:
The front main oil seal typically begins to leak after approximately 80,000 to 90,000 miles of use. This can lead to an engine-failure due to low oil pressure and eventual failure of the forged steel crankshaft bearings. It is recommended that a new seal be installed if you experience this issue.
Timing Chain Tensioner:
The timing chain tensioner can become stretched and cause the timing chain to slip. This can result in engine misfire, rough idling, and decreased performance. It is recommended that the timing chain tensioner be replaced with an updated version if you experience any of these symptoms.
Exhaust Camshaft Wear:
The exhaust camshaft in the K24 can wear out over time which can lead to incorrect intake valves timing and decreased performance. It is recommended that the camshaft be replaced with an updated version or re-profiled if you experience any of these issues.
Oil Pressure Issues:
The K24 engine is known to have oil pressure issues, as the oil passages can become clogged and restrict oil flow. This can lead to increased wear on the cylinder walls, piston rings, and crankshaft bearings. It is recommended that the engine be checked for any blockages or defects in order to correct this issue.
Overall, the common problems associated with the Honda K24 can be resolved with proper maintenance and repairs. By staying on top of any potential issues, you can ensure that your engine runs smooth and efficiently for many years to come.

How to increase the lifespan of your Honda K24A engine?
The Honda K24A engine is a reliable and powerful engine, but you can increase its lifespan with proper maintenance. Here are some tips to help keep your Honda K24A engine running like new for many years to come:
1. Change the oil regularly
Oil change intervals vary depending on the type of oil being used and the age of the engine. Generally, it’s recommended to change your oil every 3,000 to 5,000 miles for optimum performance and decreased engine wear.
2. Check your spark plugs
Spark plugs are a key component of your engine and should be checked routinely. Spark plug fouling can occur and lead to poor fuel economy and increased emissions.
3. Inspect your air filters
Your engine’s air filter is responsible for trapping dirt and debris before it can enter the combustion chamber. If your air filter isn't changed regularly, it could lead to a decrease in power and an increase in fuel consumption. Check your air filter every 6 months and replace when necessary.
4. Check your coolant levels
Coolant is essential for keeping your engine from overheating and should be checked regularly. Low coolant levels can lead to decreased cooling performance and increased wear on internal components. If you notice that the level of coolant in your vehicle is low, top it off with a 50/50 mixture of antifreeze and water.
5. Replace your timing belt
Timing belts should be replaced every 60,000 to 100,000 miles depending on the model of your vehicle. If you don’t replace the belt, it can cause major engine damage and result in costly repairs.
6. Check for fuel system leaks
Fuel system leaks can cause a decrease in engine performance, increased emissions and even fire hazards. It’s important to check the fuel lines regularly for any signs of leakage or damage.
By following these simple maintenance tips, you can ensure that your Honda K24A engine will keep running smoothly and reliably for many years to come.
