The Scion FR-S is a beloved sports car known for its lightweight design and engaging driving experience. For enthusiasts looking to enhance performance, tuning the FR-S can yield impressive results. This article explores how to achieve 250 horsepower with a budget of $1,200 in modifications.
Understanding the Scion FR-S
The Scion FR-S, developed in collaboration with Subaru, features a 2.0-liter flat-four engine that produces 200 horsepower in its stock form. Its rear-wheel-drive layout and balanced chassis make it a favorite among driving purists. However, many owners seek to extract more power from this platform.
Performance Tuning Goals
To effectively tune the FR-S to 250 horsepower, it is crucial to focus on a combination of modifications that enhance airflow, increase fuel delivery, and optimize engine management. The following sections detail the recommended modifications to reach this performance target.
1. Cold Air Intake
One of the first modifications to consider is a cold air intake system. This upgrade allows the engine to breathe better by drawing in cooler, denser air, which can improve combustion efficiency.
- Recommended Product: Injen SP Series Cold Air Intake
- Estimated Cost: $300
2. Cat-Back Exhaust System
A cat-back exhaust system not only enhances the sound of the FR-S but also reduces back pressure, allowing for better exhaust flow. This modification can help increase horsepower and torque.
- Recommended Product: Borla Cat-Back Exhaust System
- Estimated Cost: $600
3. Tune the ECU
After installing the intake and exhaust, an ECU tune is essential to optimize the engine’s performance. A proper tune adjusts fuel maps and ignition timing to take full advantage of the new modifications.
- Recommended Product: EcuTek Tune
- Estimated Cost: $400
Budget Breakdown
Here’s a summary of the costs associated with each modification:
- Cold Air Intake: $300
- Cat-Back Exhaust System: $600
- ECU Tune: $400
Adding these costs together, the total comes to $1,300. While this slightly exceeds the $1,200 target, prices can vary, and deals may be found to bring the total within budget.
Expected Performance Gains
With these modifications, many FR-S owners report achieving around 250 horsepower at the crank. Performance gains can vary based on factors such as installation quality and tuning precision.
Additional Considerations
While the primary goal is to reach 250 horsepower, it is essential to consider other aspects of performance, including handling and braking. Upgrading suspension components and brake pads can enhance the overall driving experience.
Suspension Upgrades
Improving the suspension can help maintain control during spirited driving. Consider investing in coilovers or upgraded sway bars for better handling.
- Recommended Product: BC Racing Coilovers
- Estimated Cost: $1,000 (optional)
Brake System Enhancements
Upgrading the brake pads and rotors can improve stopping power, which is vital for safety and performance. High-performance brake pads offer better grip and heat resistance.
- Recommended Product: Hawk Performance Brake Pads
- Estimated Cost: $200 (optional)
Conclusion
Tuning the Scion FR-S to achieve 250 horsepower is an attainable goal with a budget of around $1,200. By focusing on key modifications such as a cold air intake, cat-back exhaust, and ECU tune, enthusiasts can significantly enhance their driving experience. Remember to consider additional upgrades for suspension and braking to ensure a well-rounded performance vehicle.
