The Datsun 240Z is a classic sports car that has captured the hearts of enthusiasts for decades. One of the most effective ways to increase its performance is through intake upgrades. In this article, we will explore some of the best intake upgrades for the Datsun 240Z that can help you achieve a horsepower increase of 10-15 HP for under $500.
Why Upgrade the Intake?
Upgrading the intake system of your Datsun 240Z can lead to improved airflow, better engine efficiency, and increased horsepower. A well-designed intake system allows your engine to breathe more easily, which can enhance performance and responsiveness.
Best Intake Upgrades
- 1. Cold Air Intake System: A cold air intake system can significantly improve airflow to the engine. It typically features a larger diameter pipe and a high-flow air filter, which can help you achieve that desired horsepower increase.
- 2. Short Ram Intake: A short ram intake is another popular option. It replaces the factory air intake with a shorter, more direct path to the engine, reducing air resistance and improving throttle response.
- 3. High-Performance Air Filter: Sometimes, simply upgrading to a high-performance air filter can make a noticeable difference. Look for filters that are washable and reusable, as they can provide better airflow compared to standard filters.
- 4. Intake Manifold Upgrade: Upgrading the intake manifold can improve the distribution of air-fuel mixture to the cylinders, enhancing overall engine performance.
- 5. Throttle Body Spacer: Adding a throttle body spacer can increase the volume of air entering the engine, leading to improved performance. This is a cost-effective option that can complement other intake upgrades.
Cold Air Intake System
A cold air intake system is designed to draw cooler air from outside the engine bay, which is denser and can lead to more power. Many aftermarket options are available that fit the Datsun 240Z, and installation is generally straightforward.
Benefits of Cold Air Intake
- Increased horsepower and torque
- Improved throttle response
- Enhanced engine sound
Short Ram Intake
The short ram intake is an excellent choice for those looking for a simple yet effective upgrade. By reducing the length of the intake path, it allows for quicker airflow to the engine.
Advantages of Short Ram Intake
- Improved throttle response
- Easy installation
- Cost-effective performance upgrade
High-Performance Air Filter
Upgrading to a high-performance air filter is one of the simplest modifications you can make. These filters are designed to allow more air into the engine while filtering out harmful particles.
Benefits of High-Performance Air Filters
- Better airflow compared to stock filters
- Washable and reusable
- Longer lifespan than standard filters
Intake Manifold Upgrade
An upgraded intake manifold can improve the distribution of air and fuel to the engine cylinders. This modification can lead to smoother power delivery and increased horsepower.
Why Upgrade the Intake Manifold?
- Better air distribution
- Increased horsepower potential
- Enhanced engine efficiency
Throttle Body Spacer
A throttle body spacer is a simple and affordable modification that can improve airflow into the engine. It creates a larger volume of air available for combustion, which can enhance performance.
Benefits of Throttle Body Spacers
- Increased air volume
- Improved throttle response
- Cost-effective upgrade
Conclusion
Upgrading the intake system on your Datsun 240Z can lead to noticeable performance gains without breaking the bank. By choosing one or more of the upgrades mentioned above, you can achieve a 10-15 HP increase for under $500. Whether you opt for a cold air intake, short ram intake, or simply upgrade your air filter, each modification will contribute to a more enjoyable driving experience.
