The Toyota GR Corolla G16E-GTS has quickly gained a reputation among car enthusiasts for its impressive performance and handling. However, for those looking to push the limits even further, upgrading the intake system and remapping the engine can yield significant horsepower gains. In this article, we will explore how to achieve a 50+ horsepower boost with an upgraded HKS intake and remap on your GR Corolla G16E-GTS.
Understanding the GR Corolla G16E-GTS Engine
The GR Corolla is powered by a 1.6-liter turbocharged inline-three engine, which is known for its lively performance and responsiveness. The G16E-GTS engine features a direct injection system and is designed for high performance, making it an excellent candidate for upgrades. Before diving into modifications, it’s essential to understand the engine’s capabilities and limitations.
Benefits of Upgrading the Intake System
Upgrading the intake system is one of the most effective ways to increase horsepower. The stock intake system is designed for efficiency and noise reduction, but it can restrict airflow, limiting the engine’s potential. An upgraded HKS intake system offers several advantages:
- Improved Airflow: A performance intake allows for better airflow into the engine, leading to increased power and throttle response.
- Enhanced Sound: Aftermarket intakes provide a more aggressive engine sound, enhancing the driving experience.
- Weight Reduction: Many performance intakes are lighter than stock components, contributing to overall vehicle weight reduction.
Choosing the Right HKS Intake
HKS offers a variety of intake systems designed specifically for the GR Corolla. When selecting the right intake, consider the following factors:
- Type of Intake: Options include short ram intakes and cold air intakes. Short ram intakes provide quicker throttle response, while cold air intakes can offer better performance at higher speeds.
- Material Quality: Look for intakes made from high-quality materials that can withstand high temperatures and pressures.
- Compatibility: Ensure the intake is specifically designed for the G16E-GTS engine to guarantee a proper fit.
Installation Process
Installing an upgraded HKS intake is a straightforward process that can typically be completed in a few hours. Here’s a general outline of the installation steps:
- Gather Tools: You will need basic hand tools, including screwdrivers, pliers, and a socket set.
- Remove the Stock Intake: Disconnect the battery, remove any engine covers, and carefully detach the stock intake system.
- Install the HKS Intake: Follow the manufacturer’s instructions to install the new intake, ensuring all connections are secure.
- Reconnect the Battery: Once installed, reconnect the battery and check for any leaks or issues.
Engine Remapping for Maximum Performance
After upgrading the intake, the next step is to remap the engine. Remapping adjusts the engine’s fuel and timing settings to maximize the benefits of the new intake system. Here are the key aspects of the remapping process:
- ECU Tuning: The vehicle’s Engine Control Unit (ECU) needs to be reprogrammed to optimize performance with the new intake.
- Dyno Testing: It’s recommended to perform dyno testing to ensure the vehicle achieves the desired horsepower gains and to make any necessary adjustments.
- Professional Help: Consider seeking assistance from a professional tuner with experience in working with the GR Corolla to achieve the best results.
Expected Results
With the combination of an upgraded HKS intake and a proper remap, many GR Corolla owners report gains of 50+ horsepower. However, results may vary based on factors such as:
- Quality of Installation: A professional installation can lead to better results than a DIY approach.
- Environmental Conditions: Weather and altitude can affect engine performance.
- Additional Modifications: Other upgrades, such as exhaust systems or intercoolers, can also impact overall performance.
Conclusion
Upgrading the intake system and remapping the engine of your GR Corolla G16E-GTS can significantly enhance performance, providing an exhilarating driving experience. By following the steps outlined in this article, you can achieve a remarkable horsepower boost, making your GR Corolla even more thrilling on the road. Always remember to consider professional assistance for installation and tuning to ensure you maximize your vehicle’s potential.
