The AMS 20G turbo upgrade is a popular choice among enthusiasts looking to enhance the performance of their Subaru Legacy. This article explores the power gains associated with this upgrade, the mechanics behind it, and what it means for your driving experience.
Understanding the AMS 20G Turbo Upgrade
The AMS 20G turbo is designed to replace the factory turbocharger in the Subaru Legacy models, offering significant improvements in power and efficiency. This upgrade is particularly favored for its ability to maintain reliability while delivering enhanced performance.
What Is a Turbocharger?
A turbocharger is a forced induction device that compresses the intake air, allowing for more air and fuel to enter the engine. This results in increased power output without significantly increasing engine size. The AMS 20G turbo is specifically engineered to maximize these benefits for the Subaru Legacy.
Power Gains from the AMS 20G Turbo Upgrade
The power gain from installing an AMS 20G turbo can vary based on several factors, including the vehicle’s current setup, tuning, and supporting modifications. However, most users report substantial increases in horsepower and torque.
- Typical power increase: 50-100 horsepower
- Torque increase: 70-90 lb-ft
Factors Influencing Power Gains
Several factors can influence the amount of power gained from the AMS 20G turbo upgrade:
- Engine tuning: Proper tuning is essential to maximize performance and ensure engine safety.
- Supporting modifications: Upgrades such as a high-flow fuel pump, intercooler, and exhaust system can enhance power gains.
- Turbocharger condition: The overall condition of the existing engine components can affect performance.
Installation and Compatibility
Installing the AMS 20G turbo requires mechanical expertise and the right tools. It is recommended that the installation be performed by a professional or someone with significant experience in automotive modifications.
Compatibility with Subaru Legacy Models
The AMS 20G turbo is compatible with various Subaru Legacy models, particularly those equipped with the EJ20 and EJ25 engines. It is crucial to confirm compatibility with your specific model year and engine type before purchasing.
Tuning Your Legacy for Optimal Performance
