Preparation Steps

Begin by preparing your workspace and the vehicle. This will make the installation process smoother.

  • Park the vehicle on a flat surface and engage the parking brake.
  • Disconnect the negative battery terminal to prevent any electrical issues.
  • Remove the engine cover if applicable.

Removing the Stock BOV

With the preparation complete, you can now remove the stock BOV from the FD RX-7.

  • Locate the stock BOV on the intake manifold.
  • Disconnect the vacuum line from the stock BOV.
  • Remove the bolts securing the stock BOV using the socket set.
  • Carefully pull the stock BOV off the manifold and set it aside.

Installing the HKS Sequential BOV

Now it’s time to install the HKS Sequential BOV. Follow these steps carefully.

  • Take the new HKS BOV and position it on the intake manifold.
  • Align the mounting holes and secure the BOV with the provided bolts.
  • Use a torque wrench to tighten the bolts to the manufacturer’s specifications.
  • Reconnect the vacuum line to the new BOV, ensuring a snug fit.

Connecting the Silicone Couplers

To ensure proper airflow, you need to connect the silicone couplers to the BOV and intake piping.

  • Slide the silicone coupler onto the BOV outlet.
  • Attach the other end of the coupler to the intake piping.
  • Secure both ends with clamps to prevent any leaks.

Final Steps

With the BOV installed, it’s time to complete the process and check your work.

  • Double-check all connections and ensure everything is secure.
  • Reconnect the negative battery terminal.
  • Start the engine and listen for any unusual sounds.
  • Take the vehicle for a test drive to experience the performance gains.

Tuning Considerations

After installation, consider tuning your RX-7 for optimal performance with the new BOV.

  • Check for any boost leaks and resolve them immediately.
