by

The Nissan 240SX is a beloved platform among car enthusiasts, particularly for its tuning potential and performance upgrades. One of the most effective upgrades you can make is installing JWT S3 camshafts. This article will guide you through the installation process step-by-step, ensuring you get the most out of your Nissan 240SX.

What You Will Need

  • JWT S3 Camshafts
  • Socket set
  • Torque wrench
  • Camshaft installation tool
  • Engine oil
  • New camshaft seals
  • Gasket sealant
  • Basic hand tools

Preparation

Before you begin the installation process, make sure your workspace is clean and organized. Gather all necessary tools and parts. It’s also important to have a repair manual for your specific model year of the Nissan 240SX for reference.

Step 1: Remove the Engine Cover

Start by disconnecting the negative battery terminal to prevent any electrical issues. Next, remove the engine cover by unscrewing the bolts that hold it in place. This will give you access to the camshaft area.

Step 2: Remove the Valve Cover

Once the engine cover is off, you will need to remove the valve cover. Carefully unbolt the valve cover and lift it off. Make sure to keep track of the bolts and any gaskets that may come off with it.

Step 3: Align the Timing Marks

Before removing the old camshafts, you must align the timing marks on the crankshaft and camshaft gears. This step is crucial to ensure that your engine timing is correct when you install the new camshafts.

Step 4: Remove the Old Camshafts

Using your socket set, carefully unbolt the old camshafts from their positions. Take note of the order and placement of the bolts, as you will need to follow the same procedure when installing the new camshafts.

Step 5: Install the JWT S3 Camshafts

Now it’s time to install the JWT S3 camshafts. Before placing them in, apply a bit of engine oil to the camshaft journals to ensure smooth operation. Carefully position the new camshafts and bolt them in place using the original bolts.

Step 6: Replace Camshaft Seals

With the new camshafts in place, it’s a good idea to replace the camshaft seals. Remove the old seals and install the new ones, applying a small amount of gasket sealant to ensure a proper seal.

Step 7: Reinstall the Valve Cover

After everything is secure, it’s time to reinstall the valve cover. Make sure to use a new gasket or the old one if it is still in good condition. Tighten the bolts to the manufacturer’s specified torque settings.

Step 8: Reattach the Engine Cover

Once the valve cover is back on, reattach the engine cover. Make sure all bolts are tightened properly and that there are no loose components.

Step 9: Reconnect the Battery

Reconnect the negative battery terminal. This step completes the installation process, but it’s important to perform a final inspection before starting your engine.

Step 10: Start the Engine

Start your Nissan 240SX and listen for any unusual sounds. If everything sounds good, take your car for a test drive to experience the performance boost from your new JWT S3 camshafts.

Conclusion

Installing JWT S3 camshafts on your Nissan 240SX is a rewarding project that enhances your vehicle’s performance. By following these steps carefully, you can ensure a successful installation and enjoy the benefits of increased horsepower and torque.
