What turbos do Subarus use?
Subaru vehicles are renowned for their performance, reliability, and unique engineering, particularly their use of turbocharged engines in many models. If you're a Subaru enthusiast or a car owner curious about the turbos used in these vehicles, this article will provide a detailed breakdown of the types of turbos Subaru employs and what makes them special.
Subaru's Turbocharged Legacy
Subaru has a long history of using turbocharged engines, especially in their performance-oriented models like the WRX, WRX STI, and the Forester XT. Turbochargers are a key component in enhancing engine performance by forcing more air into the engine, allowing for more fuel to be burned and thus generating more power. Subaru's turbos are specifically designed to complement their signature Boxer engine layout, ensuring optimal performance and reliability.
Types of Turbos Used in Subaru Vehicles
Subaru uses a variety of turbochargers across its lineup, depending on the model and its intended purpose. Here are the most common types:
- IHI Turbochargers: Subaru frequently uses IHI turbos, such as the VF series (e.g., VF39, VF48). These are commonly found in models like the WRX STI and are known for their reliability and performance.
- Mitsubishi Turbochargers: Some Subaru models, particularly older ones, use Mitsubishi turbos like the TD04 and TD05. These are smaller turbos that provide quick spool times, making them ideal for daily driving and low-end torque.
- Garrett Turbochargers: Garrett turbos are often used in aftermarket applications for Subaru vehicles. While not typically factory-installed, they are a popular upgrade for enthusiasts looking for higher performance.
- Twin-Scroll Turbochargers: In some models, such as the JDM (Japanese Domestic Market) Subaru Legacy, twin-scroll turbos are used. These turbos improve efficiency and reduce turbo lag by splitting the exhaust pulses into two separate scrolls.
Each of these turbo types is selected based on the specific needs of the vehicle, whether it's for high performance, fuel efficiency, or a balance of both.
Why Subaru Turbos Stand Out
Subaru's turbos are uniquely paired with their Boxer engines, which have a horizontally opposed cylinder layout. This design lowers the vehicle's center of gravity, improving handling and stability. The combination of a Boxer engine and a turbocharger provides a smooth power delivery and a thrilling driving experience, making Subaru vehicles a favorite among car enthusiasts.
Maintenance Tips for Subaru Turbochargers
To ensure the longevity and performance of your Subaru's turbocharger, follow these maintenance tips:
- Use high-quality synthetic oil and change it regularly to keep the turbo well-lubricated.
- Allow the engine to warm up before driving aggressively to prevent thermal shock to the turbo.
- Let the engine idle for a minute or two after driving hard to allow the turbo to cool down gradually.
- Inspect and replace the air filter as needed to prevent debris from entering the turbo.
- Schedule regular maintenance with a trusted mechanic to catch any potential issues early.
Proper care and maintenance can significantly extend the life of your turbocharger and keep your Subaru running at peak performance.
Conclusion
Subaru's use of turbochargers is a testament to their commitment to performance and innovation. Whether you're driving a WRX STI with an IHI VF48 turbo or a Forester XT with a Mitsubishi TD04, these turbos are designed to deliver power and reliability. By understanding the types of turbos Subaru uses and maintaining them properly, you can enjoy the full potential of your vehicle for years to come.
