- ECU Tuning
- Upgraded Fuel System
Engine Modifications
Upgrading the engine is the most crucial step. This may involve installing a high-performance camshaft, pistons, and headers. The cost for these modifications can vary widely based on the specific parts and labor involved.
Performance Exhaust System
A performance exhaust system helps improve airflow, which is essential for achieving higher horsepower. Look for high-flow catalytic converters and mufflers designed for performance.
Cold Air Intake
A cold air intake system can significantly enhance engine performance by allowing cooler, denser air to enter the engine. This upgrade is relatively easy to install and offers a good return on investment.
ECU Tuning
ECU tuning adjusts the engine’s computer settings to optimize performance based on your new modifications. This is a critical step that can unlock additional horsepower and improve overall drivability.
Upgraded Fuel System
To support increased horsepower, an upgraded fuel system is necessary. This may include larger fuel injectors and a high-performance fuel pump to ensure your engine receives the necessary fuel flow.
