1. Tune-up:
* Spark plugs & wires: Worn plugs and wires can hinder engine performance. Replace them with new ones that match your engine specifications.
* Air filter: A clogged air filter restricts airflow, impacting power. Ensure your air filter is clean or replace it if necessary.
* Fuel filter: A clogged fuel filter can restrict fuel flow. Replacing it can improve fuel delivery and combustion.
2. Intake & Exhaust:
* Intake manifold: Consider cleaning your existing intake manifold or exploring affordable aftermarket options for a slight improvement.
* Exhaust system: A free-flowing exhaust system can increase power. Check for leaks or blockages. Replacing the exhaust system can be expensive, but a simple muffler replacement can improve sound and flow.
3. Engine Management:
* Timing: Proper ignition timing is crucial for optimal combustion and power. If you're comfortable with this, adjust it according to the manufacturer's specifications.
* Fuel/air mixture: A lean or rich mixture can negatively impact performance. Consult a mechanic for proper fuel/air mixture adjustments.
4. Accessories:
* Underdrive pulleys: These can slightly reduce accessory load, freeing up some horsepower for torque.
Important Notes:
* Maintenance: Always prioritize basic maintenance to ensure your engine runs optimally.
* Professional Help: If you're not comfortable with mechanical work, consult a trusted mechanic for advice and repairs.
* Safety First: Always prioritize safety while working on your vehicle.
Remember: These are low-cost, relatively minor modifications that can make a slight difference. For significant torque increases, consider more substantial upgrades like engine modifications or turbocharging, but these can be costly.
