Datsun 510 Intake Manifold Swap: Adding 10-15 Hp with $400 Parts

by

The Datsun 510 is a classic car beloved by enthusiasts for its lightweight design and racing pedigree. One of the most effective ways to boost performance is by swapping the intake manifold. This article will guide you through the process of swapping the intake manifold on a Datsun 510, helping you add 10-15 horsepower with an investment of around $400.

Understanding the Datsun 510

The Datsun 510, produced from 1968 to 1973, is known for its nimble handling and strong engine options. The stock intake manifold is functional but can restrict airflow, limiting the engine’s potential. Upgrading to a performance intake manifold can significantly enhance horsepower and torque.

Benefits of an Intake Manifold Swap

Swapping the intake manifold on your Datsun 510 offers several key benefits:

  • Increased Airflow: A performance manifold improves airflow to the engine, enhancing combustion efficiency.
  • Improved Throttle Response: Better airflow results in quicker throttle response, making the car more enjoyable to drive.
  • Higher Horsepower: Expect a gain of 10-15 horsepower with the right parts.
  • Enhanced Engine Sound: A new manifold can change the engine’s sound, adding to the overall driving experience.

Choosing the Right Intake Manifold

When selecting an intake manifold for your Datsun 510, consider the following factors:

  • Material: Aluminum manifolds are lighter and offer better heat dissipation compared to cast iron.
  • Design: Look for a manifold designed for performance, with a focus on maximizing airflow.
  • Compatibility: Ensure the manifold is compatible with your engine’s specifications.
  • Brand Reputation: Choose reputable brands known for quality and performance.

Here are a few recommended intake manifolds that fit the Datsun 510 and can be found within the $400 budget:

  • Weber DCOE Manifold: This manifold is designed for use with Weber carburetors and offers excellent performance gains.
  • Fidenza Racing Intake Manifold: Known for its lightweight design and improved airflow characteristics.
  • Holley Performance Intake: A reliable choice that can deliver significant horsepower increases.

Tools and Materials Needed

Before starting the swap, gather the necessary tools and materials:

  • Tools: Socket set, wrenches, torque wrench, screwdrivers, gasket scraper, and pliers.
  • Materials: New intake manifold, gaskets, and any necessary hardware.

Step-by-Step Installation Guide

Step 1: Preparation

Begin by disconnecting the battery and removing any components that obstruct access to the intake manifold. This may include the air cleaner, throttle linkage, and fuel lines.

Step 2: Remove the Old Manifold

Carefully remove the bolts securing the old intake manifold. Use a gasket scraper to clean the surfaces on the engine to ensure a good seal for the new manifold.

Step 3: Install the New Manifold

Position the new intake manifold onto the engine, ensuring it aligns correctly with the bolt holes. Install new gaskets and secure the manifold with the appropriate bolts, tightening them to the manufacturer’s specifications.

Step 4: Reassemble Components

Reattach any components you removed earlier, including the air cleaner and throttle linkage. Double-check all connections and ensure there are no leaks.

Step 5: Final Checks

Reconnect the battery and start the engine. Allow it to warm up and check for any irregularities in performance. Take the car for a test drive to experience the improvements firsthand.

Maintenance and Considerations

After completing the intake manifold swap, consider the following maintenance tips:

  • Regular Inspections: Check for leaks and ensure all components remain secure.
  • Clean Air Filter: A clean air filter will help maintain optimal airflow to the engine.
  • Monitor Performance: Keep an eye on engine performance and make adjustments as necessary.

Conclusion

Swapping the intake manifold on your Datsun 510 is a cost-effective way to enhance performance, adding 10-15 horsepower with a budget of around $400. By following the steps outlined in this guide, you can enjoy the benefits of improved throttle response and a more exhilarating driving experience.
