The Nissan 350Z is a beloved sports car known for its sleek design and powerful performance. This article chronicles the journey of building a 350Z equipped with the VQ35DE engine, transforming it from a stock vehicle to a powerhouse with 500 horsepower. Below, we will outline the modifications made, the challenges faced, and the ultimate results of this exhilarating build.
Introduction to the VQ35DE Engine
The VQ35DE engine is a 3.5-liter V6 that powers the Nissan 350Z. It is known for its strong performance and tunability. Understanding the engine’s capabilities is crucial for anyone looking to modify their 350Z effectively.
Initial Stock Performance
When the build began, the stock VQ35DE engine produced approximately 287 horsepower and 274 lb-ft of torque. While this was respectable for a sports car, the goal was to significantly increase these numbers through various modifications.
Modifications Overview
The journey to 500 horsepower involved a series of modifications across various systems of the car. Below is a comprehensive list of the modifications made during the build:
- Cold air intake system
- High-performance headers
- Full cat-back exhaust system
- Upgraded fuel injectors
- Aftermarket fuel pump
- ECU tuning
- Upgraded intercooler
- Supercharger installation
- Performance camshafts
- Upgraded cooling system
- Lightweight flywheel
- High-performance clutch
Step-by-Step Modifications
1. Cold Air Intake System
The first modification was the installation of a cold air intake system. This upgrade allowed the engine to breathe better, improving throttle response and overall performance.
2. High-Performance Headers
Next, high-performance headers were added to reduce exhaust back pressure. This modification enhances exhaust flow and contributes to a noticeable increase in horsepower.
3. Full Cat-Back Exhaust System
A full cat-back exhaust system was installed to further improve exhaust flow and sound. This upgrade not only adds power but also gives the car a more aggressive exhaust note.
4. Upgraded Fuel Injectors and Pump
With the increase in airflow, upgraded fuel injectors and a higher-capacity fuel pump were necessary to ensure the engine received the correct fuel mixture for optimal performance.
5. ECU Tuning
After all the hardware modifications, an ECU tune was performed. This step is crucial as it calibrates the engine management system to optimize performance based on the new modifications.
6. Supercharger Installation
The centerpiece of the build was the installation of a supercharger. This forced induction system dramatically increases the engine’s power output, pushing it towards the 500 horsepower goal.
7. Performance Camshafts
To maximize the benefits of the supercharger, performance camshafts were installed. These camshafts improve airflow and engine efficiency, further increasing horsepower.
8. Upgraded Cooling System
With the increase in power comes the need for better cooling. An upgraded cooling system was installed to prevent overheating during high-performance driving.
9. Lightweight Flywheel and High-Performance Clutch
Finally, a lightweight flywheel and high-performance clutch were added to improve throttle response and ensure the drivetrain could handle the increased power without slipping.
Results of the Build
After completing all the modifications, the 350Z was taken to a dynamometer for testing. The results were impressive, with the engine producing a staggering 500 horsepower and 450 lb-ft of torque at the wheels.
Conclusion
The journey from a stock Nissan 350Z to a 500 horsepower monster was filled with challenges and learning experiences. Each modification contributed to the overall performance and driving experience. This build log serves as a guide for enthusiasts looking to enhance their own VQ35DE engines.
