Understanding the Subaru Legacy GT
The Subaru Legacy GT features a turbocharged 2.5-liter flat-four engine, which provides a solid base for performance modifications. The goal of this article is to outline the potential upgrades that can be made to increase horsepower while staying within a reasonable budget.
Performance Upgrades Overview
- ECU Tune
- Intake System
- Exhaust System
- Intercooler Upgrade
- Boost Control
1. ECU Tune
An ECU (Engine Control Unit) tune is one of the most effective ways to increase horsepower. By remapping the engine parameters, a tune can optimize fuel delivery and boost pressure.
- Cost: $500
- Expected HP Gain: 30-50 HP
2. Intake System
Upgrading the intake system allows for better airflow into the engine, which can lead to improved performance. A high-performance air intake can help the engine breathe better.
- Cost: $300
- Expected HP Gain: 10-20 HP
3. Exhaust System
A performance exhaust system reduces back pressure and enhances exhaust flow. This upgrade not only improves horsepower but also gives the car a more aggressive sound.
- Cost: $600
- Expected HP Gain: 15-25 HP
4. Intercooler Upgrade
Upgrading the intercooler can help maintain lower intake temperatures, which is crucial for performance, especially when increasing boost pressure. A larger intercooler can significantly improve efficiency.
- Cost: $700
- Expected HP Gain: 20-30 HP
5. Boost Control
Installing a boost controller allows for precise adjustments to boost levels. This upgrade can help maximize power output while maintaining engine reliability.
- Cost: $400
- Expected HP Gain: 20-40 HP
