The Nissan R32 GT-R is a legendary vehicle, known for its impressive performance and engineering. One of the key modifications enthusiasts often pursue to enhance power and response is the installation of upgraded camshafts. In this article, we will explore the benefits of installing HKS 272 or 272+ camshafts in the R32 GT-R.
Understanding Camshafts
Camshafts play a crucial role in the engine’s performance by controlling the timing and duration of the intake and exhaust valves. Upgrading to performance camshafts can significantly improve engine breathing, leading to better power and throttle response.
Benefits of HKS 272 and 272+ Camshafts
The HKS 272 and 272+ camshafts are designed to maximize the performance of the RB26DETT engine found in the R32 GT-R. Here are some key benefits:
- Increased Power Output: These camshafts allow for a higher lift and longer duration, resulting in increased airflow and power.
- Improved Throttle Response: Enhanced valve timing leads to quicker engine response, making the car feel more lively.
- Optimized RPM Range: The HKS 272 and 272+ camshafts are tuned to perform well across a broad RPM range, providing flexibility for different driving styles.
Installation Process
Installing HKS camshafts in an R32 GT-R requires careful planning and execution. Here’s a step-by-step guide to help you through the process.
Tools and Materials Needed
- Socket set
- Torque wrench
- Camshaft locking tool
- New camshaft seals
- Engine oil
Step-by-Step Installation
- Preparation: Ensure the engine is cool and disconnect the battery.
- Remove the Valve Covers: Unbolt the valve covers and set them aside.
- Remove the Old Camshafts: Use the camshaft locking tool to hold the camshafts in place while removing the sprockets and old camshafts.
- Install New Camshafts: Place the HKS camshafts in their respective positions and torque the sprockets to the manufacturer’s specifications.
- Reassemble: Replace the valve covers with new gaskets and reconnect any disconnected components.
- Check Timing: Verify the timing is set correctly before starting the engine.
Tuning Considerations
After installing the HKS 272 or 272+ camshafts, it is essential to tune the engine for optimal performance. A proper tune will ensure that the air-fuel mixture is adjusted to match the new camshaft profile, maximizing power and efficiency.
Choosing a Tuner
Selecting a qualified tuner who understands the RB26DETT engine and the effects of camshaft upgrades is crucial. Look for tuners with experience in performance modifications and positive reviews from other R32 GT-R owners.
Potential Issues and Solutions
While upgrading camshafts can yield significant performance gains, there are potential issues to be aware of:
- Idle Quality: After installing aggressive camshafts, the engine may experience a rough idle. This can often be resolved through proper tuning.
- Increased Noise: Performance camshafts can lead to more engine noise. Ensure that all components are properly lubricated to minimize wear and noise.
- Compatibility with Other Mods: Ensure that your other modifications, such as turbo upgrades and exhaust systems, are compatible with the new camshafts for optimal performance.
Conclusion
Upgrading to HKS 272 or 272+ camshafts in your R32 GT-R can provide significant improvements in power and throttle response. With careful installation and tuning, you can unleash the full potential of your iconic Nissan sports car. Whether you are a seasoned enthusiast or a newcomer to performance mods, this upgrade is a worthwhile consideration for enhancing your driving experience.
