The H22 engine, a popular choice among Honda enthusiasts, offers a solid foundation for performance upgrades. One of the most impactful modifications you can make is swapping out the stock camshaft for a performance camshaft. This guide will walk you through the steps of performing an H22 camshaft swap, detailing the costs involved and the potential power gains you can expect.
Understanding the H22 Engine
The H22 engine, known for its high-revving nature and robust design, is a 2.2-liter inline-four engine produced by Honda. It was primarily used in models like the Honda Prelude and Accord. The engine is well-regarded for its tuning potential, making it a favorite among car enthusiasts.
Benefits of a Performance Camshaft
Upgrading to a performance camshaft can significantly enhance your H22’s performance. Here are some of the benefits:
- Increased Power: A performance camshaft can improve horsepower and torque.
- Better Throttle Response: Enhanced cam profiles can lead to quicker acceleration.
- Improved Engine Sound: Performance camshafts often create a more aggressive engine note.
- Higher RPM Capability: Many performance cams allow for higher rev limits.
Choosing the Right Camshaft
When selecting a performance camshaft for your H22, consider the following factors:
- Intended Use: Determine if your car will be used for daily driving, track racing, or show purposes.
- Lift and Duration: Higher lift and longer duration can yield more power but may affect drivability.
- Brand Reputation: Choose reputable brands known for quality and performance.
- Compatibility: Ensure the camshaft is compatible with your specific H22 variant.
Tools and Materials Needed
Before starting your camshaft swap, gather the necessary tools and materials:
- Tools:
- Socket set
- Torque wrench
- Screwdrivers
- Camshaft timing tool
- Engine hoist (if needed)
- Materials:
- Performance camshaft
- New camshaft seals
- Gasket maker or new gaskets
- Engine oil
Step-by-Step Camshaft Swap Process
Step 1: Preparation
Start by disconnecting the battery and draining the engine oil. This step ensures safety and prevents spills during the swap.
Step 2: Remove Engine Components
To access the camshaft, you will need to remove several components:
- Intake manifold
- Valve cover
- Timing belt and covers
- Camshaft gears
Step 3: Remove the Old Camshaft
Once the components are removed, carefully take out the old camshaft. Pay attention to the orientation and position of the timing marks.
Step 4: Install the New Camshaft
Position the new performance camshaft in place, making sure it aligns with the timing marks. Replace the camshaft seals to prevent leaks.
Step 5: Reassemble the Engine
Reinstall all the components you removed in reverse order. Make sure to torque all bolts to the manufacturer’s specifications.
Step 6: Final Checks
Before starting the engine, double-check all connections and ensure everything is secured properly. Refill the engine with oil and reconnect the battery.
Step 7: Start the Engine
Start the engine and let it idle for a few minutes. Listen for any unusual noises and check for leaks. After a successful startup, take the car for a test drive to feel the improvements.
Cost Breakdown
The cost of a camshaft swap can vary based on several factors, including the camshaft brand and whether you perform the work yourself or hire a professional. Here’s a rough estimate:
- Performance Camshaft: $300 – $800
- Gaskets and Seals: $50 – $100
- Tools (if not owned): $100 – $300
- Labor (if hiring): $200 – $500
Expected Power Gains
After completing the camshaft swap, you can expect significant power gains. Depending on the camshaft chosen and supporting modifications, power increases can range from:
- 10-30 horsepower: With a mild performance camshaft.
- 30-50 horsepower: With a more aggressive camshaft and tuning.
Conclusion
Swapping the camshaft in your H22 engine is a rewarding project that can enhance performance and driving enjoyment. With careful planning, the right tools, and a quality performance camshaft, you can achieve impressive power gains and take your Honda to the next level.
