1. Engine modifications:
- Install a turbocharger or supercharger: This is one of the most effective ways to increase power output, but it can be expensive.
- Upgrade the intercooler, intake, and exhaust systems: This will help to improve airflow and increase engine efficiency.
- Install high-performance spark plugs, ignition coils, and fuel injectors: This will help to optimize ignition and fuel delivery for better performance.
- Tune the ECU: This will allow you to adjust the engine's air-fuel mixture, timing, and other settings to maximize performance.
2. Drivetrain modifications:
- Replace the clutch with a high-performance unit: This will help to reduce driveline losses and improve acceleration.
- Install a short shifter kit: This will give you shorter throws between gears for quicker shifting.
- Upgrade the driveshaft and axles: This will help to reduce weight and improve drivetrain efficiency.
3. Suspension and braking modifications:
- Install coilovers or lowering springs: This will lower the car's centre of gravity and improve handling.
- Upgrade the shocks and struts: This will help to improve ride comfort and control.
- Install larger brake rotors and calipers: This will improve stopping power and reduce fade.
4. Weight reduction:
- Remove unnecessary weight from the car, such as the spare tire, jack, and rear seats.
- Replace heavy parts with lightweight alternatives, such as aluminum or carbon fibre.
5. Aerodynamic modifications:
- Add a front splitter, rear diffuser, and side skirts to improve the car's aerodynamics.
The cost of these modifications will vary depending on the specific parts you choose and the labour involved in the installation. You should budget at least several thousand dollars for significant performance improvements.
It's important to note that some modifications may not be legal in all jurisdictions, so be sure to check with your local laws before making any changes.
