The Nissan 370Z, equipped with the VQ37VHR engine, has gained a reputation for its performance and tuning potential. However, as enthusiasts push the limits of this platform, maintaining reliability becomes crucial. This article explores essential cooling and drivetrain upgrades that enhance performance while ensuring the longevity of your 370Z.
Understanding the Importance of Cooling Upgrades
High-performance builds generate significant heat, especially under stress. The stock cooling system may struggle to keep temperatures in check, leading to potential engine damage. Upgrading the cooling system is vital for maintaining optimal operating temperatures during spirited driving or track days.
Upgrading the Radiator
A high-performance radiator is one of the first upgrades to consider. Aftermarket options often feature larger cores and improved flow characteristics, which help dissipate heat more effectively than the stock unit.
- Consider brands like Mishimoto or CSF for quality upgrades.
- Look for radiators with a larger core size for better cooling efficiency.
Installing an Oil Cooler
Engine oil plays a critical role in lubrication and cooling. An oil cooler helps maintain lower oil temperatures, which is especially important during high-performance driving. This upgrade can prevent oil breakdown and ensure consistent engine performance.
- Choose an oil cooler that fits within the engine bay without obstructing airflow.
- Consider a thermostatic oil cooler to regulate oil temperature effectively.
Upgrading the Intercooler
If your 370Z is equipped with a forced induction system, an upgraded intercooler is essential. A larger intercooler reduces intake temperatures, improving performance and reliability.
- Look for a front-mount intercooler for optimal airflow.
- Consider options with high-efficiency cores for better heat dissipation.
Enhancing Drivetrain Reliability
The drivetrain of the 370Z is another critical area for upgrades, especially when increasing power output. Ensuring that the components can handle the added stress is essential for reliability.
Upgrading the Clutch
A high-performance clutch can significantly enhance the engagement and durability of your drivetrain. Stock clutches may slip under increased power levels, leading to poor performance and potential damage.
- Consider options from brands like Exedy or ACT for reliable performance.
- Look for multi-disc clutches for improved torque handling.
Replacing the Differential
The differential is crucial for power transfer to the wheels. Upgrading to a limited-slip differential (LSD) can improve traction and stability, especially during aggressive driving.
- Choose a clutch-type LSD for better performance on the track.
- Consider gearing options that suit your driving style and powerband.
Driveshaft Upgrades
An upgraded driveshaft can reduce rotational mass and improve power transfer efficiency. Lightweight options can enhance acceleration and responsiveness, making them a worthy investment for performance builds.
- Look for aluminum or carbon fiber driveshafts for weight savings.
- Ensure compatibility with your existing components for a seamless installation.
Conclusion
Maintaining reliability in high-performance 370Z VQ37VHR builds involves careful consideration of cooling and drivetrain upgrades. By investing in quality components, enthusiasts can enjoy enhanced performance without sacrificing the longevity of their vehicles. Always consult with professionals and conduct thorough research before making modifications to ensure the best results for your build.
