The Subaru BRZ, known for its lightweight chassis and rear-wheel-drive layout, has become a favorite among car enthusiasts. With the FA20 engine, it delivers a balanced performance right off the showroom floor. However, for those looking to push the limits, upgrading the turbo and ECU tuning can unlock remarkable potential, transforming the BRZ into a 10-second quarter-mile machine.
Understanding the FA20 Engine
The FA20 engine is a 2.0-liter flat-four engine that produces a respectable amount of horsepower and torque. Its design contributes to a low center of gravity, enhancing the vehicle’s handling characteristics. However, the stock power output can be significantly improved with the right modifications.
Upgrading the Turbocharger
One of the most effective ways to increase the power of the FA20 engine is by upgrading the turbocharger. A larger turbo can provide more air to the engine, resulting in increased horsepower and torque. Here are some popular turbo upgrade options:
- Garrett GT2860RS Turbo
- Blouch 1.5XTR Turbo
- ATP GT28RS Turbo
Each of these turbochargers offers different performance characteristics, so it’s essential to choose one that aligns with your performance goals. Additionally, installing a larger intercooler can help keep intake temperatures down, allowing for more efficient power delivery.
ECU Tuning for Maximum Performance
After upgrading the turbo, the next critical step is ECU tuning. The engine’s computer must be reprogrammed to optimize performance with the new turbo setup. Tuning can adjust fuel maps, ignition timing, and boost levels to ensure the engine runs efficiently and safely.
- Accessport by COBB Tuning
- EcuTek ProECU
- Hondata FlashPro
Using one of these tuning solutions, a professional tuner can help achieve the desired performance metrics while maintaining reliability. Proper tuning is crucial to avoid engine damage and ensure that the car performs at its best.
Supporting Modifications
To support the increased power from the turbo and ensure the engine runs smoothly, several additional modifications are recommended:
- Upgraded fuel injectors
- High-flow fuel pump
- Performance exhaust system
- Upgraded clutch and transmission components
These supporting modifications help manage the increased power and ensure the vehicle can handle the demands of high-performance driving.
Achieving the 10-Second Quarter Mile
With the right combination of upgrades and tuning, achieving a 10-second quarter mile is within reach for BRZ owners. Here are some key factors to consider:
- Weight reduction: Remove unnecessary components to lighten the car.
- Tire selection: Choose high-performance tires for better traction.
- Launch control: Utilize launch control systems for optimal starts.
- Driver skill: Practice and refine your driving technique for consistent runs.
By focusing on these elements, drivers can maximize their chances of hitting that coveted 10-second mark in the quarter mile.
Conclusion
The Subaru BRZ, with its FA20 engine, can be transformed into a formidable contender at the drag strip with the right upgrades. By investing in a larger turbocharger, proper ECU tuning, and supporting modifications, enthusiasts can achieve impressive performance numbers, including a 10-second quarter mile. Whether for street use or track days, these enhancements elevate the driving experience to new heights.
