The Nissan 350Z is a beloved sports car that has captured the hearts of enthusiasts around the world. With its sleek design and powerful VQ35DE engine, it provides an excellent platform for performance upgrades. In this article, we will explore how to take a stock 350Z and transform it into a beast producing 350 wheel horsepower (WHP) with an Injen intake, E85 conversion, and a turbocharger.
Understanding the VQ35DE Engine
The VQ35DE is a 3.5-liter V6 engine known for its reliability and performance potential. It features an aluminum alloy block and DOHC design, making it a great candidate for modifications. Before diving into upgrades, it’s essential to understand the engine’s capabilities and limitations.
Initial Modifications
Before achieving 350 WHP, several initial modifications are necessary. These upgrades will lay the groundwork for further enhancements and ensure the engine can handle the increased power.
- High-performance spark plugs
- Upgraded fuel injectors
- Performance exhaust system
- ECU tuning
High-Performance Spark Plugs
Upgrading to high-performance spark plugs will improve ignition efficiency and combustion, which is crucial for maximizing power output.
Upgraded Fuel Injectors
To support the increased fuel demand from the turbocharger, installing larger fuel injectors is necessary. This ensures that the engine receives the right amount of fuel for optimal performance.
Performance Exhaust System
A performance exhaust system helps reduce back pressure and improves exhaust flow, allowing the engine to breathe better and produce more power.
ECU Tuning
ECU tuning is essential to optimize the engine’s performance parameters. A professional tune will adjust fuel maps and ignition timing, ensuring the engine runs smoothly with the new modifications.
Injen Intake Installation
The next step in the build is installing an Injen cold air intake. This modification enhances airflow to the engine, resulting in improved throttle response and increased horsepower.
Benefits of the Injen Intake
The Injen intake offers several advantages:
- Increased horsepower and torque
- Better engine sound
- Improved fuel efficiency
E85 Conversion
Converting to E85 fuel is a game-changer for performance. E85 has a higher octane rating than regular gasoline, allowing for more aggressive tuning and increased power output.
Advantages of E85 Fuel
Using E85 fuel comes with several benefits:
- Higher horsepower potential
- Lower engine temperatures
- Reduced engine knock
Turbocharger Installation
The final step in achieving 350 WHP is the installation of a turbocharger. A quality turbo kit will significantly increase the engine’s power output while maintaining reliability.
Choosing the Right Turbo Kit
When selecting a turbo kit, consider the following:
- Turbo size and type
- Intercooler options
- Included components (manifolds, piping, etc.)
Installation Process
Installing a turbocharger requires careful planning and execution. It’s recommended to follow the manufacturer’s instructions and consult with professionals if needed.
Tuning for 350 WHP
After all modifications are complete, a final tune is crucial to ensure the engine runs optimally with the new turbo setup. A professional tuner will adjust the ECU settings to maximize power while maintaining reliability.
Conclusion
Transforming a stock Nissan 350Z into a 350 WHP powerhouse involves several modifications, including an Injen intake, E85 conversion, and turbo installation. With the right upgrades and tuning, you can unleash the full potential of the VQ35DE engine and enjoy an exhilarating driving experience.
