The automotive world is constantly evolving, and enthusiasts are always on the lookout for ways to enhance their vehicles’ performance. One of the most effective methods for increasing power is through turbo upgrades. In this article, we will explore the impact of a 19T turbo upgrade on the performance of your Legacy.
Understanding Turbochargers
A turbocharger is a device that forces more air into the engine’s combustion chamber, allowing it to burn more fuel and produce more power. This process significantly enhances engine performance without a significant increase in engine size or weight.
What is a 19T Turbo?
The 19T turbo is a popular upgrade among automotive enthusiasts, particularly for Subaru Legacy models. It is known for its ability to provide a substantial increase in horsepower and torque compared to stock turbos.
Specifications of the 19T Turbo
The 19T turbo features a larger compressor and turbine wheel compared to smaller stock turbos. This allows for improved airflow and quicker spool times, resulting in better throttle response and overall performance.
Benefits of Upgrading to a 19T Turbo
Upgrading to a 19T turbo can yield several benefits for your Legacy, including:
- Increased Horsepower: A 19T turbo can provide a significant boost in horsepower, often exceeding 300 whp with supporting modifications.
- Improved Torque: Enhanced torque delivery can improve acceleration and responsiveness.
- Better Throttle Response: A larger turbo can spool faster, leading to improved throttle response.
- Enhanced Performance: Overall performance improvements make driving more enjoyable and engaging.
Installation Considerations
Installing a 19T turbo requires careful planning and consideration. Here are some key points to keep in mind:
- Supporting Modifications: To maximize the benefits of a 19T turbo, consider upgrading other components such as the intercooler, exhaust system, and fuel injectors.
- Tuning: Proper tuning is essential to ensure the engine runs efficiently and safely with the new turbo.
- Installation Expertise: It is advisable to have a professional install the turbo to avoid potential issues.
Performance Gains with a 19T Turbo Upgrade
Many Legacy owners who have upgraded to a 19T turbo report impressive performance gains. These gains can be quantified in several ways:
- Horsepower Increase: Owners often see increases of 50-100 whp over stock turbos.
- Torque Improvements: Torque can increase by 50-70 lb-ft, providing a noticeable difference in acceleration.
- Faster 0-60 Times: Many report improved 0-60 times, often in the low 5-second range.
Real-World Examples
Several Subaru Legacy owners have shared their experiences after upgrading to a 19T turbo. Here are a few real-world examples:
- Example 1: A 2005 Legacy GT owner upgraded to a 19T turbo and saw a jump from 250 whp to 320 whp after tuning.
- Example 2: Another owner reported improved throttle response and a decrease in 0-60 times from 6.5 seconds to 5.2 seconds.
- Example 3: A Legacy owner with supporting mods achieved a peak torque of 400 lb-ft, enhancing daily driving and spirited runs.
Potential Drawbacks
While upgrading to a 19T turbo has many benefits, there are potential drawbacks to consider:
- Increased Wear: Higher power outputs can lead to increased wear on engine components.
- Fuel Requirements: A 19T turbo may require higher octane fuel for optimal performance.
- Cost: The total cost of the upgrade, including supporting modifications and tuning, can be significant.
Conclusion
In summary, upgrading to a 19T turbo can significantly enhance the performance of your Subaru Legacy. With increased horsepower, improved torque, and better throttle response, the driving experience becomes more exhilarating. However, it is essential to consider supporting modifications and professional installation to ensure the best results. For those looking to elevate their Legacy’s performance, a 19T turbo upgrade is a worthy investment.
