A carburetor upgrade is a classic way to enhance the engine's breathing and overall responsiveness.
• Intake and Exhaust Systems: Upgrading the intake and exhaust systems can significantly improve engine performance. A cold air intake will allow your engine to breathe easier by bringing in cooler, denser air. Pair this with a performance exhaust system, which reduces backpressure and helps expel exhaust gases more efficiently. These upgrades not only boost power but also give your Civic a more aggressive sound. An aftermarket header can further optimize exhaust flow, maximizing the benefits of the exhaust system upgrade.
• Ignition System: An upgraded ignition system can improve combustion efficiency, leading to better throttle response and power. Consider installing a high-performance ignition coil, spark plugs, and ignition wires. These components provide a stronger spark, ensuring more complete combustion of the air-fuel mixture. This upgrade is especially beneficial when combined with other engine modifications, such as a carburetor upgrade or performance camshaft.
• Camshaft Upgrade: Swapping the stock camshaft for a performance camshaft can dramatically alter the engine's power curve. A performance camshaft increases valve lift and duration, allowing more air and fuel into the cylinders. This results in a broader powerband and increased horsepower. When choosing a camshaft, consider your driving style and desired performance characteristics. A more aggressive camshaft will deliver more top-end power but may sacrifice some low-end torque.

These modifications can transform your engine's performance, making your Honda Civic 81 Hatchback much more fun to drive. Remember, it's always a good idea to consult with a professional mechanic or tuner to ensure that your modifications are installed correctly and safely.

Suspension and Handling

Improving the suspension and handling of your Honda Civic 81 Hatchback is crucial for enhancing its overall driving experience. The original suspension setup, while adequate for daily driving, can be significantly improved for better cornering and stability. Here are some popular suspension and handling upgrades:

• Lowering Springs: Lowering springs are a simple and effective way to improve your Civic's handling. They lower the car's center of gravity, reducing body roll and improving cornering ability. Lowering springs also give your Civic a more aggressive stance. When choosing lowering springs, consider the ride height and spring rate. A moderate drop of around 1 to 1.5 inches is typically a good balance between improved handling and ride comfort.
• Shock Absorbers/Struts: Upgrading the shock absorbers or struts is essential for maximizing the benefits of lowering springs. Performance shocks provide better damping control, reducing bouncing and improving overall stability. Brands like Bilstein and Koni offer high-quality shocks that are designed to work well with lowering springs. Adjustable shocks allow you to fine-tune the suspension to your specific driving preferences.
• Sway Bars: Upgrading the sway bars can significantly reduce body roll and improve cornering performance. Sway bars connect the left and right wheels, increasing the stiffness of the suspension and reducing the amount of body roll during turns. Aftermarket sway bars are typically thicker and stiffer than the stock sway bars, providing a noticeable improvement in handling. Consider upgrading both the front and rear sway bars for balanced handling.
• Bushings: Replacing worn or soft bushings with polyurethane bushings can improve suspension response and handling. Polyurethane bushings are stiffer than the stock rubber bushings, reducing suspension flex and improving steering precision. This upgrade is especially beneficial for older cars like the Civic 81 Hatchback, where the original bushings may be worn out. Replacing the bushings in the control arms, sway bars, and steering rack can make a significant difference in handling.

Upgrading the suspension and handling components of your Honda Civic 81 Hatchback will not only improve its performance but also make it more enjoyable to drive. A well-tuned suspension system will give you more confidence behind the wheel, whether you're cruising around town or tackling twisty roads.

Brakes

Don't forget about the brakes! Upgrading the braking system on your Honda Civic 81 Hatchback is essential for safety and performance. The original brakes, while adequate for normal driving, may not be sufficient for spirited driving or racing. Here are some popular brake upgrades:

• Brake Pads: Upgrading to performance brake pads is a simple and effective way to improve braking performance. Performance brake pads offer a higher coefficient of friction, providing more stopping power and better resistance to brake fade. Choose brake pads that are designed for your specific driving style and needs. For street driving, a good set of performance street pads will provide a noticeable improvement over the stock pads. For track use, consider more aggressive track-oriented pads.
• Brake Rotors: Upgrading to performance brake rotors can further enhance braking performance. Slotted or drilled rotors offer better heat dissipation and improved wet weather performance. Slotted rotors help to remove brake dust and gases, while drilled rotors provide additional cooling. Consider upgrading to larger rotors for even more stopping power. This upgrade typically requires new calipers and brackets.
• Brake Lines: Replacing the stock rubber brake lines with stainless steel braided brake lines can improve brake pedal feel and responsiveness. Stainless steel brake lines do not expand under pressure like rubber lines, providing a firmer and more consistent pedal feel. This upgrade is especially beneficial for older cars like the Civic 81 Hatchback, where the original rubber lines may be deteriorating.
• Brake Master Cylinder: Upgrading the brake master cylinder can improve braking performance, especially when combined with other brake upgrades. A larger master cylinder can provide more fluid volume, resulting in a firmer and more responsive pedal feel. This upgrade is especially beneficial for cars with upgraded calipers or larger brake rotors.

By upgrading the braking system on your Honda Civic 81 Hatchback, you'll not only improve its stopping power but also enhance your safety on the road. A well-balanced braking system is crucial for confident and controlled driving, especially when you're pushing the limits of your car's performance.
