Tools and Materials Needed
To successfully install the HKS intake and turbo kit, you will need the following tools and materials:
- Socket set
- Wrenches
- Screwdrivers
- Torque wrench
- Pipe cutters (if necessary)
- Heat-resistant silicone hoses
- Vacuum line
- ECU tuning software (if applicable)
Having these tools on hand will streamline the installation process and help avoid any unnecessary delays.
Step-by-Step Installation Guide
1. Preparing the Vehicle
Before starting the installation, make sure the vehicle is parked on a flat surface and the engine is cool. Disconnect the battery to prevent any electrical issues during the process.
2. Removing the Stock Intake
Begin by removing the stock air intake system. This typically involves:
- Loosening the clamps on the intake hose
- Disconnecting any sensors connected to the intake
- Removing the air filter box
Set aside the stock components as they may be needed for future reference or reinstallation.
3. Installing the HKS Intake
With the stock intake removed, you can now install the HKS intake system. Follow these steps:
- Position the new intake pipe in place and secure it with the provided clamps.
- Attach the high-flow air filter to the end of the intake pipe.
- Reconnect any sensors as required.
Ensure all connections are tight to prevent any air leaks.
4. Removing the Stock Turbocharger
Next, you will need to remove the stock turbocharger. This step includes:
- Disconnecting the oil and coolant lines from the turbo.
- Removing the turbo mounting bolts.
- Carefully lifting the turbo out of the engine bay.
Take care during this process to avoid damaging any surrounding components.
5. Installing the HKS Turbocharger
With the stock turbo removed, you can now install the HKS turbocharger:
- Place the new turbo in position and secure it with the mounting bolts.
- Reconnect the oil and coolant lines, ensuring they are tight and leak-free.
- Install the new intercooler and connect the piping as per the kit instructions.
Double-check all connections before proceeding to the next step.
6. Connecting the ECU
The final step in the installation process is connecting the ECU. This may involve:
- Plugging in the ECU tuning software.
- Adjusting the fuel maps and boost settings as per the new setup.
- Ensuring all electrical connections are secure.
Consult the HKS manual for specific tuning recommendations to optimize performance.
Testing and Tuning
After completing the installation, it is essential to test the vehicle to ensure everything is functioning correctly. Start the engine and listen for any unusual sounds. Check for leaks around the intake and turbo connections. Once you are satisfied, take the car for a test drive to assess performance.
Conclusion
Installing the HKS intake and turbo kit on your Mitsubishi Evo VIII can lead to a remarkable increase in horsepower and overall performance. By following the steps outlined in this guide, you can enhance your driving experience and enjoy the benefits of increased power. Always remember to consult professionals if you are uncertain about any part of the installation process.
