The Miata has long been celebrated for its lightweight and agile handling. However, many enthusiasts seek to boost its performance further. Installing a supercharger can significantly enhance the power output of your Miata. In this guide, we will walk you through the step-by-step installation of both Vortech V-3 Si and Jackson Racing Roots supercharger kits.
Tools and Materials Needed
- Socket set
- Wrenches
- Torque wrench
- Phillips and flathead screwdrivers
- Drill and drill bits
- Supercharger kit (Vortech V-3 Si or Jackson Racing Roots)
- Installation manual
- Coolant
- Oil
- Vacuum hose
- Zip ties
- Safety goggles
- Gloves
Preparation
Before starting the installation, ensure you have all the necessary tools and materials. It’s also important to work in a well-ventilated area and wear safety goggles and gloves for protection.
1. Disconnect the Battery
Begin by disconnecting the negative terminal of the battery to prevent any electrical issues during installation.
2. Remove the Engine Cover
Use a socket set to remove the bolts securing the engine cover. Carefully lift it off and set it aside.
3. Drain the Coolant
Locate the drain plug on the radiator and drain the coolant into a suitable container. This step is crucial as you will need to remove hoses later.
Installing the Vortech V-3 Si Supercharger
4. Install the Bracket
Follow the instructions in the Vortech manual to install the supercharger bracket. Ensure it is securely fastened to the engine.
5. Mount the Supercharger
Attach the Vortech V-3 Si supercharger to the bracket. Use the provided bolts and a torque wrench to secure it according to the specifications in the manual.
6. Connect the Intake Piping
Connect the intake piping from the supercharger to the throttle body. Ensure all clamps are tight to prevent air leaks.
7. Install the Fuel Pump and Injectors
Replace the stock fuel pump with a high-flow pump as specified in the Vortech kit. Also, install the high-flow injectors to accommodate the increased fuel requirements.
8. Connect the Oil Lines
Attach the oil lines from the engine to the supercharger. Make sure to use the correct fittings and ensure there are no leaks.
9. Refill Coolant and Oil
Refill the coolant and oil in the engine. Check for any leaks before proceeding.
Installing the Jackson Racing Roots Supercharger
10. Install the Roots Supercharger Bracket
Begin by installing the bracket for the Jackson Racing Roots supercharger. Follow the specific instructions provided in the kit for proper alignment and securing.
11. Mount the Roots Supercharger
Carefully mount the Jackson Racing Roots supercharger onto the bracket. Use the appropriate hardware to secure it tightly.
12. Connect the Intake Manifold
Attach the intake manifold to the supercharger, ensuring a good seal. Check all bolts and clamps for tightness.
13. Upgrade the Fuel System
Similar to the Vortech installation, upgrade the fuel pump and injectors to meet the demands of the Roots supercharger.
14. Install the Cooling System
Install the additional cooling system components that come with the Jackson Racing kit to ensure optimal performance under boost.
15. Final Checks
Double-check all connections, hoses, and bolts. Refill coolant and oil as necessary, and ensure there are no leaks.
Testing the Installation
Once the installation is complete, reconnect the battery and start the engine. Monitor the gauges for oil pressure and coolant temperature. Take the vehicle for a test drive, gradually increasing the RPMs to ensure everything is functioning correctly.
Conclusion
Installing a supercharger on your Miata can significantly enhance its performance. Whether you choose the Vortech V-3 Si or the Jackson Racing Roots kit, following these steps will help ensure a successful installation. Always refer to the specific installation manuals provided with your kit for the most accurate guidance.
