The RB20DET engine is a popular choice among car enthusiasts, known for its potential to produce impressive power and performance. One of the most effective upgrades for this engine is the installation of a Trust Greddy intake manifold. This upgrade can significantly enhance airflow, improve throttle response, and ultimately lead to better performance. In this article, we will guide you through the step-by-step process of installing a Trust Greddy intake manifold on your RB20DET.
Tools and Materials Needed
- Trust Greddy intake manifold
- Socket set
- Wrench set
- Torque wrench
- Gasket scraper
- New gaskets
- Throttle body cleaner
- Rags
- Vacuum line caps
Preparation
Before starting the installation, ensure that your vehicle is parked on a flat surface and the engine is cool. Disconnect the negative battery terminal to prevent any electrical issues during the process.
Remove the Existing Intake Manifold
Begin by removing the existing intake manifold. Follow these steps:
- Disconnect all electrical connectors from the throttle body and sensors.
- Remove the air intake duct and any associated piping.
- Unbolt the throttle body from the manifold and set it aside.
- Remove any vacuum lines connected to the intake manifold.
- Unbolt the intake manifold from the engine block using the socket set.
- Carefully lift the old manifold off the engine.
Clean the Engine Surface
Once the old manifold is removed, use a gasket scraper to clean the engine surface thoroughly. Ensure that no old gasket material remains, as this can cause leaks when the new manifold is installed.
Installing the Trust Greddy Intake Manifold
Now that the engine surface is clean, it’s time to install the Trust Greddy intake manifold. Follow these steps:
- Place the new gasket onto the engine surface, ensuring it aligns with the bolt holes.
- Carefully position the Trust Greddy intake manifold onto the gasket.
- Hand-tighten the bolts to hold the manifold in place.
- Using a torque wrench, tighten the bolts to the manufacturer’s specifications in a crisscross pattern to ensure even pressure.
Reattach the Throttle Body
After securing the manifold, reattach the throttle body:
- Align the throttle body with the intake manifold and place it on the new manifold.
- Use the socket set to secure the throttle body bolts.
- Reconnect all electrical connectors and vacuum lines that were previously disconnected.
Final Steps
With the intake manifold and throttle body securely in place, it’s time to complete the installation:
- Reconnect the air intake duct and any associated piping.
- Double-check all connections and ensure everything is secure.
- Reconnect the negative battery terminal.
Testing the Installation
Before taking your vehicle for a drive, it’s essential to test the installation:
- Start the engine and let it idle for a few minutes.
- Check for any vacuum leaks around the intake manifold and throttle body.
- Listen for any unusual noises that could indicate a problem.
- Once satisfied, take the car for a test drive to assess performance.
Conclusion
Installing a Trust Greddy intake manifold on your RB20DET can significantly enhance your vehicle’s performance. By following the steps outlined in this guide, you can ensure a successful installation and enjoy the benefits of improved airflow and throttle response. Always remember to take your time and double-check your work for the best results.
