The Toyota 86 is a beloved sports car known for its engaging driving experience and balanced handling. One of the popular modifications among enthusiasts is the installation of a lightweight flywheel. This upgrade can significantly enhance the car’s response and performance, making it a worthwhile investment for those looking to improve their driving experience. In this article, we will explore the benefits of a lightweight flywheel and provide a detailed guide on how to install one for around $300.
What is a Lightweight Flywheel?
A lightweight flywheel is a performance part that reduces the rotational mass of the engine’s flywheel. This reduction allows the engine to rev more quickly, improving throttle response and overall performance. The stock flywheel in the Toyota 86 is relatively heavy, which can hinder performance, especially in high-revving situations.
Benefits of Installing a Lightweight Flywheel
- Improved Throttle Response: A lighter flywheel allows the engine to rev more freely, leading to quicker throttle response.
- Enhanced Acceleration: With less mass to move, the engine can accelerate faster, improving overall speed and performance.
- Better Engine Rev Matching: A lightweight flywheel makes it easier to match engine RPMs during downshifts, enhancing driving smoothness.
- Increased Engine Rev Range: The engine can reach higher RPMs more quickly, allowing for a broader power band.
Tools and Materials Needed
- Lightweight flywheel (specific to Toyota 86)
- Torque wrench
- Socket set
- Ratchet
- Jack and jack stands
- Clutch alignment tool
- Engine oil (for lubrication)
- Safety glasses and gloves
Step-by-Step Installation Guide
Step 1: Preparation
Before starting the installation, ensure that you have all the necessary tools and materials. Park the Toyota 86 on a flat surface and engage the parking brake. Disconnect the battery to prevent any electrical issues during the installation.
Step 2: Lift the Vehicle
Using a jack, lift the front of the vehicle and secure it with jack stands. Make sure the car is stable before proceeding to work underneath it.
Step 3: Remove the Transmission
To access the flywheel, you will need to remove the transmission. Start by disconnecting the driveshaft and any electrical connections attached to the transmission. Remove the bolts securing the transmission to the engine and carefully slide the transmission away from the engine.
Step 4: Remove the Stock Flywheel
With the transmission removed, you can now access the stock flywheel. Remove the bolts securing the flywheel to the engine using a socket wrench. Carefully take off the flywheel, ensuring that the clutch assembly is not damaged in the process.
Step 5: Install the Lightweight Flywheel
Before installing the lightweight flywheel, apply a thin layer of engine oil to the contact surfaces to ensure smooth operation. Align the new flywheel with the mounting holes and secure it using the bolts removed earlier. Use a torque wrench to tighten the bolts to the manufacturer’s specifications.
Step 6: Reassemble the Transmission
Once the lightweight flywheel is securely in place, reattach the transmission. Make sure to reconnect the driveshaft and any electrical connections. Ensure that all bolts are tightened to the specified torque settings.
Step 7: Lower the Vehicle and Reconnect the Battery
Carefully lower the vehicle back to the ground using the jack. Once the car is on a flat surface, reconnect the battery. Start the engine and listen for any unusual noises that may indicate an installation issue.
Conclusion
Installing a lightweight flywheel in your Toyota 86 can significantly enhance your driving experience by improving throttle response and acceleration. With the right tools and a bit of mechanical knowledge, this modification can be completed for around $300. Enjoy the newfound performance and responsiveness of your vehicle!
