The Toyota GR86 has gained popularity among car enthusiasts for its engaging driving experience and performance potential. One of the most effective ways to enhance the performance of the GR86 is through intake and exhaust modifications. In this article, we will explore the costs, installation processes, and expected power gains from these modifications.
Understanding Intake and Exhaust Mods
Before diving into specifics, it’s essential to understand what intake and exhaust modifications entail. The intake system is responsible for bringing air into the engine, while the exhaust system expels gases after combustion. Enhancing these systems can lead to improved airflow, resulting in better engine performance.
Intake Modifications
Upgrading the intake system on your GR86 can lead to significant power gains. There are various types of intake modifications available, each with its own benefits and costs.
Types of Intake Mods
- Cold Air Intake: This system draws cooler air from outside the engine bay, improving combustion efficiency.
- Short Ram Intake: This option is designed for quicker throttle response by shortening the intake path.
- High-Performance Air Filters: These filters can enhance airflow without replacing the entire intake system.
Cost of Intake Mods
The cost of intake modifications can vary widely based on the type of system chosen. Here’s a breakdown of typical costs:
- Cold Air Intake: $300 – $600
- Short Ram Intake: $200 – $400
- High-Performance Air Filters: $50 – $150
Installation Process
Installing an intake system is generally straightforward and can often be done with basic tools. Here’s a simple guide:
- Gather necessary tools: socket set, screwdrivers, and pliers.
- Remove the factory intake system by disconnecting hoses and clamps.
- Install the new intake system by following the manufacturer’s instructions.
- Reconnect any hoses and ensure everything is secured properly.
Expected Power Gains
After installing an intake modification, drivers can expect power gains ranging from 5 to 15 horsepower, depending on the system and other modifications made.
Exhaust Modifications
Exhaust modifications are equally crucial for enhancing the performance of the GR86. Upgrading the exhaust system can improve exhaust flow, reduce back pressure, and enhance engine sound.
Types of Exhaust Mods
- Cat-Back Exhaust System: This system replaces the entire exhaust from the catalytic converter back, providing significant performance improvements.
- Axle-Back Exhaust System: This option replaces the rear section of the exhaust, offering a more affordable upgrade.
- High-Performance Mufflers: Upgrading just the muffler can enhance sound and performance without a full system replacement.
Cost of Exhaust Mods
Similar to intake modifications, the costs for exhaust upgrades can vary based on the type of system. Here’s a typical cost breakdown:
- Cat-Back Exhaust System: $600 – $1,200
- Axle-Back Exhaust System: $300 – $700
- High-Performance Mufflers: $100 – $300
Installation Process
Installing an exhaust system can be more complex than an intake, but it’s still manageable for those with some mechanical skills. Here’s a basic installation guide:
- Gather required tools: jack stands, socket set, and exhaust clamps.
- Lift the car and secure it on jack stands for safety.
- Remove the factory exhaust system by unbolting it from the catalytic converter and removing hangers.
- Install the new exhaust system, ensuring all connections are tight and secure.
Expected Power Gains
With exhaust modifications, drivers can expect power gains of approximately 10 to 20 horsepower, depending on the system and the overall setup of the vehicle.
Combining Intake and Exhaust Mods
For optimal performance, many GR86 owners choose to combine both intake and exhaust modifications. This approach maximizes airflow and can lead to even greater power gains.
Benefits of Combining Mods
- Enhanced throttle response and acceleration.
- Improved engine sound and driving experience.
- Potential for increased horsepower and torque.
Cost Considerations
When planning for both intake and exhaust modifications, it’s essential to budget accordingly. The total cost can range from $1,000 to $2,000 or more, depending on the chosen components and installation fees.
Installation Tips
For those looking to install both modifications, consider the following tips:
- Plan the installation to allow for easy access to both systems.
- Consider professional installation if unsure about the process.
- Test drive the vehicle after installation to ensure everything is functioning correctly.
Conclusion
Upgrading the intake and exhaust systems on your Toyota GR86 can significantly enhance performance, sound, and driving enjoyment. By understanding the costs, installation processes, and potential power gains, you can make informed decisions about your modifications. Whether you choose to tackle the installation yourself or seek professional help, these upgrades are sure to elevate your GR86 experience.
