Upgrading your KA24DE engine with a JWT S3 camshaft can lead to significant performance gains. This guide will walk you through the installation process step-by-step, helping you achieve an increase of up to 25 horsepower for around $450.
What You Will Need
- JWT S3 Camshaft
- Basic hand tools (wrenches, sockets, etc.)
- Torque wrench
- Engine oil
- Camshaft installation tool (optional)
- Timing chain kit (recommended)
- Gasket set
Preparation Steps
Before you start the installation, ensure you have a clean workspace and all necessary tools and parts ready. It’s also a good idea to disconnect the battery to prevent any electrical issues during the process.
1. Remove the Engine Cover
Start by removing the engine cover. This usually involves unscrewing a few bolts that hold it in place. Set the cover aside in a safe location.
2. Disconnect the Necessary Components
Next, disconnect the throttle body, intake manifold, and any sensors that may obstruct access to the camshaft. Label the connections to ensure easy reassembly.
3. Drain Engine Oil
Drain the engine oil to prevent any spills when removing the camshaft. Make sure to use a suitable container to catch the oil.
Removing the Old Camshaft
With the engine prepared, you can now focus on removing the old camshaft. Follow these steps carefully to avoid damage.
1. Remove the Timing Chain Cover
Unscrew and remove the timing chain cover. This may require some effort, as the gasket can stick. Be gentle to avoid damaging the cover.
2. Remove the Timing Chain
Once the timing cover is off, remove the timing chain. Make sure to note how it is positioned for reinstallation.
3. Take Out the Old Camshaft
Now you can access the camshaft. Carefully remove the old camshaft by unscrewing the retaining bolts. Keep these bolts safe for the new installation.
Installing the JWT S3 Camshaft
With the old camshaft removed, it’s time to install the new JWT S3 camshaft. Follow these steps closely for a successful installation.
1. Prepare the New Camshaft
Before installation, apply a small amount of engine oil to the journals of the new camshaft. This will help with lubrication during the initial startup.
2. Install the New Camshaft
Carefully place the new camshaft into the engine. Make sure it aligns properly with the timing chain and the journals.
3. Secure the Camshaft
Using the retaining bolts from the old camshaft, secure the new camshaft in place. Be sure to torque these bolts to the manufacturer’s specifications.
Reassembly
Now that the camshaft is installed, it’s time to reassemble the engine components you previously removed.
1. Reinstall the Timing Chain
Reattach the timing chain, ensuring it is properly aligned and tensioned according to specifications.
2. Replace the Timing Chain Cover
Secure the timing chain cover back onto the engine, using a new gasket to prevent leaks.
3. Reconnect All Components
Reconnect the throttle body, intake manifold, and any sensors you disconnected earlier. Double-check all connections to ensure nothing is left loose.
Final Steps
With everything reassembled, it’s time to finalize the installation.
1. Fill with Engine Oil
Refill the engine with fresh engine oil. Check the oil level to ensure it’s within the proper range.
2. Reconnect the Battery
Reconnect the battery and ensure all electrical connections are secure.
3. Start the Engine
Start the engine and allow it to idle for a few minutes. Listen for any unusual noises and check for leaks.
Conclusion
Installing a JWT S3 camshaft in your KA24DE can significantly boost performance. With this guide, you should be able to complete the installation for around $450 and enjoy the benefits of an additional 25 horsepower. Happy driving!
