The FA20 engine has gained a reputation for its performance and tuning potential among automotive enthusiasts. One of the most effective upgrades for this engine is the installation of an Invidia downpipe, which can significantly increase horsepower and torque. In this article, we will explore the power gains achieved by upgrading to an Invidia downpipe, taking the FA20 engine from 268 to an impressive 310 horsepower.
Understanding the FA20 Engine
The FA20 engine is a 2.0-liter flat-four engine developed by Subaru and Toyota. It features a DOHC design with direct fuel injection, which enhances efficiency and performance. This engine is found in various models, including the Subaru BRZ and Toyota 86, and has become popular for its balance of power and handling.
What is a Downpipe?
A downpipe is a component of the exhaust system that connects the turbocharger to the rest of the exhaust. It plays a crucial role in improving exhaust flow, reducing back pressure, and enhancing overall engine performance. Upgrading to an aftermarket downpipe, such as the Invidia downpipe, can lead to substantial power gains.
Power Gains from Invidia Downpipe
When installing an Invidia downpipe on an FA20 engine, enthusiasts have reported significant increases in horsepower. The stock FA20 engine typically produces around 268 horsepower, but with the addition of the Invidia downpipe, this figure can rise to approximately 310 horsepower. This increase is achieved through several factors:
- Improved exhaust flow
- Reduced turbo lag
- Enhanced throttle response
Benefits of Upgrading to an Invidia Downpipe
Upgrading to an Invidia downpipe offers several benefits beyond just horsepower gains. These include:
- Sound Improvement: The Invidia downpipe enhances the exhaust note, providing a more aggressive sound that many enthusiasts appreciate.
- Weight Reduction: Aftermarket downpipes are often lighter than stock components, contributing to a reduction in overall vehicle weight.
- Increased Efficiency: Better exhaust flow can lead to improved fuel efficiency under certain driving conditions.
Installation Process
Installing an Invidia downpipe requires some mechanical knowledge and tools. Here’s a brief overview of the installation process:
- Gather necessary tools: socket set, wrenches, and a torque wrench.
- Lift the vehicle securely using jack stands.
- Remove the stock downpipe by disconnecting the exhaust and any sensors.
- Install the Invidia downpipe, ensuring proper alignment and securing all bolts.
- Reconnect any sensors and exhaust components.
- Lower the vehicle and start the engine to check for leaks.
Tuning Considerations
After upgrading to an Invidia downpipe, it is essential to consider tuning the engine to maximize performance. A proper tune can optimize fuel maps and ignition timing, ensuring that the engine runs efficiently with the new downpipe. This step is crucial to avoid potential issues such as engine knock or running too lean.
Conclusion
Upgrading to an Invidia downpipe is one of the most effective modifications for the FA20 engine, providing impressive power gains from 268 to 310 horsepower. With the added benefits of improved sound, weight reduction, and increased efficiency, it’s a modification that many enthusiasts consider essential. If you are looking to enhance your FA20 engine’s performance, the Invidia downpipe is a worthwhile investment.
