Upgrading the S2000 Ap1’s Intake Manifold for Better Power at High Rpm

The Honda S2000 AP1 is a beloved sports car known for its high-revving engine and agile handling. One of the most effective upgrades for enhancing performance at high RPM is the intake manifold. Upgrading the intake manifold can lead to significant improvements in airflow, throttle response, and overall engine efficiency.

Understanding the Intake Manifold

The intake manifold is a crucial component of the engine’s air intake system. It distributes the air-fuel mixture to the engine cylinders. In the S2000 AP1, the stock manifold is designed for a balance of performance and drivability. However, for enthusiasts looking to maximize power at higher RPMs, an aftermarket intake manifold can provide the necessary improvements.

Benefits of Upgrading the Intake Manifold

  • Improved Airflow: Aftermarket manifolds are designed to enhance airflow, allowing the engine to breathe better at high RPM.
  • Increased Power: More efficient airflow translates to more power, particularly in the upper RPM range.
  • Better Throttle Response: Upgraded manifolds can improve throttle response, making the car feel more responsive during acceleration.
  • Weight Reduction: Some aftermarket options are lighter than the stock manifold, contributing to better overall performance.

Choosing the Right Intake Manifold

When selecting an intake manifold for the S2000 AP1, it’s essential to consider several factors:

  • Material: Common materials include aluminum and composite. Aluminum is durable, while composite can offer weight savings.
  • Design: Look for designs that optimize airflow and fit well with the engine’s characteristics.
  • Brand Reputation: Choose reputable brands known for quality and performance.
  • Compatibility: Ensure the manifold is compatible with your specific model and any other modifications you have made.

Installation Process

Installing an aftermarket intake manifold on the S2000 AP1 requires some mechanical skill. Here’s a general overview of the installation process:

  • Gather Tools: You will need basic hand tools, including wrenches, sockets, and screwdrivers.
  • Remove Stock Manifold: Start by disconnecting the battery, removing the engine cover, and then carefully detaching the stock intake manifold.
  • Prepare New Manifold: Clean the mating surfaces and install any necessary gaskets or seals on the new manifold.
  • Install New Manifold: Position the new manifold and secure it in place, ensuring all connections are tight and leak-free.
  • Reconnect Components: Reattach any hoses, sensors, and the battery before starting the engine.

Tuning After Installation

After upgrading the intake manifold, tuning the engine is crucial to fully realize the performance benefits. Proper tuning ensures that the air-fuel mixture is optimized for the new manifold, preventing issues such as lean conditions or poor performance.

  • ECU Remapping: A professional ECU remap can adjust fuel maps and ignition timing for improved performance.
  • Dyno Testing: Consider having the car dyno-tested to measure power gains and ensure everything is functioning correctly.
  • Monitor Performance: Keep an eye on engine parameters to ensure reliability and performance after the upgrade.

Conclusion

Upgrading the intake manifold on the Honda S2000 AP1 is a powerful modification that can significantly enhance performance at high RPM. With improved airflow, increased power, and better throttle response, this upgrade is a favorite among enthusiasts. By carefully selecting the right manifold, following proper installation procedures, and tuning the engine, drivers can unlock the full potential of their S2000.
