The Nissan 370Z, powered by the VQ37VHR engine, is a beloved platform for enthusiasts looking to enhance performance. Achieving 500 horsepower is a common goal among tuners, and with the right upgrades, it’s entirely possible. This article will focus on two key areas: camshaft upgrades and ECU flashing using Stillen components.
Understanding the VQ37VHR Engine
The VQ37VHR engine is a 3.7-liter V6 known for its robust design and potential for tuning. To reach the 500 hp mark, it’s essential to understand its components and how they work together. The engine features:
- Aluminum alloy construction for reduced weight
- Variable Valve Event and Lift (VVEL) for improved performance
- High compression ratio for better power output
Camshaft Upgrades
Upgrading the camshaft is one of the most effective ways to increase horsepower. A performance camshaft can improve airflow and enhance engine efficiency. Here’s what to consider when selecting camshafts for your 370Z:
Choosing the Right Camshaft
When selecting a camshaft for the VQ37VHR, consider the following:
- Lift and Duration: Higher lift and longer duration can increase airflow.
- Compatibility: Ensure the camshaft is designed specifically for the VQ37VHR.
- Brand Reputation: Look for reputable brands like Stillen that offer quality camshaft options.
Installation Process
Installing a new camshaft requires precision and care. Here’s a brief overview of the installation process:
- Remove the engine cover and necessary components to access the camshaft.
- Disconnect the timing chain and remove the old camshaft.
- Install the new camshaft, ensuring proper alignment and torque specifications.
ECU Flashing with Stillen
After upgrading the camshaft, the next step is to flash the ECU to optimize the engine’s performance. ECU flashing adjusts the fuel maps and ignition timing to match the new camshaft specifications.
Benefits of ECU Flashing
Flashing the ECU provides several advantages:
- Improved throttle response and acceleration
- Enhanced fuel efficiency
- Maximized power output to reach the 500 hp goal
Flashing Process
The ECU flashing process typically involves the following steps:
- Connect the OBD-II scanner to the vehicle’s diagnostic port.
- Download the current ECU map for backup.
- Upload the new performance map provided by Stillen.
Additional Upgrades for Achieving 500 HP
While camshaft upgrades and ECU flashing are critical, additional modifications can also help reach the 500 hp target. Consider the following upgrades:
- High-performance intake and exhaust systems
- Upgraded fuel injectors and fuel pump
- Forced induction options like superchargers or turbochargers
Conclusion
Reaching 500 horsepower on a Nissan 370Z VQ37VHR is an achievable goal with the right upgrades. By focusing on camshaft enhancements and ECU flashing with Stillen, enthusiasts can unlock the full potential of their engines. Always remember to consider additional modifications to support your performance goals and ensure a balanced setup.
