Installing a lightweight flywheel on your Scion FR-S can significantly enhance acceleration and overall performance. This guide will walk you through the steps necessary to complete this modification safely and effectively.
What You Will Need
- Lightweight flywheel
- Socket set
- Torque wrench
- Flywheel lock tool
- Engine oil
- Safety glasses
- Mechanic’s gloves
Preparation Steps
Before starting the installation, ensure you have all necessary tools and parts ready. Park your Scion FR-S on a level surface and engage the parking brake. Disconnect the battery to avoid any electrical issues.
Removing the Engine Cover
Begin by removing the engine cover to access the flywheel. Use a socket wrench to unscrew the bolts securing the cover and carefully lift it off.
Accessing the Transmission
Next, you will need to remove the transmission. Start by disconnecting the driveshaft from the rear differential. Then, unbolt the transmission mount and support the transmission with a jack.
Removing the Old Flywheel
With the transmission removed, you can now access the flywheel. Use a flywheel lock tool to prevent the engine from rotating while you unbolt the flywheel. Remove the bolts in a crisscross pattern to avoid warping.
Installing the Lightweight Flywheel
Position the new lightweight flywheel onto the crankshaft. Ensure it is aligned correctly and then insert the bolts. Tighten the bolts in a crisscross pattern to the manufacturer’s specified torque settings.
Reassembling the Transmission
Once the flywheel is securely in place, reattach the transmission. Ensure that all bolts are tightened properly and that the driveshaft is reconnected to the rear differential.
Final Steps
Replace the engine cover and reconnect the battery. Start the engine to ensure everything is functioning correctly. Listen for any unusual noises that may indicate a problem.
Benefits of a Lightweight Flywheel
A lightweight flywheel offers several advantages for your Scion FR-S, including:
- Improved engine response
- Faster acceleration
- Reduced rotational mass
- Enhanced throttle response
Conclusion
Installing a lightweight flywheel on your Scion FR-S is a straightforward process that can lead to significant performance improvements. With the right tools and careful attention to detail, you can enhance your vehicle’s acceleration and driving experience.
