Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- Socket set and wrenches
- Torque wrench
- Camshaft installation tool
- Engine oil
- New camshaft and lifters

Step-by-Step Installation Guide
Step 1: Prepare the Engine
Start by disconnecting the battery and removing any components that obstruct access to the engine, such as the intake manifold and valve covers. Make sure to label and keep track of all bolts and parts removed.
Step 2: Remove the Old Camshaft
Remove the timing chain cover and the old timing chain. Use a camshaft installation tool to carefully extract the old camshaft. Be cautious not to damage any surrounding components during this process.
Step 3: Install the New Turbo Cam
Before installing the new Turbo Cam, apply a thin coat of engine oil to the camshaft and lifters to ensure proper lubrication. Carefully slide the new camshaft into place, making sure it aligns with the timing chain. Reinstall the timing chain and cover, following the manufacturer’s torque specifications.
Step 4: Reassemble the Engine
Reattach the valve covers and intake manifold, ensuring that all gaskets are in good condition to prevent leaks. Double-check that all bolts are tightened to the correct specifications.
Step 5: Final Checks
Before starting the engine, reconnect the battery and check all fluid levels. Ensure that the oil and coolant are topped off. It’s also a good idea to spin the engine manually to ensure everything is functioning correctly before cranking it.
Testing and Tuning
After installation, it’s crucial to test and tune your engine to maximize the benefits of the new camshaft. Follow these steps:
- Start the engine: Listen for any unusual noises that may indicate a problem.
- Check for leaks: Look for any oil or coolant leaks around the camshaft and other components.
- Tune the engine: You may need to adjust the carburetor or fuel injection settings for optimal performance.
- Test drive: Take the vehicle for a test drive to feel the difference in performance.
