The 4G63 engine has long been a favorite among car enthusiasts, particularly in the Mitsubishi Eclipse and Lancer Evolution models. Known for its robust design and tuning potential, the 4G63 can be significantly upgraded with the right modifications. In this article, we will explore the power gains achieved through a turbo upgrade using the HKS Turbo Kit compared to the stock setup, as tested on a dynamometer.
Understanding the 4G63 Engine
The 4G63 is a 2.0-liter inline-four engine that features a DOHC design and a turbocharger in its performance variants. Its strong internals and ability to handle increased boost make it a prime candidate for upgrades. The engine’s architecture allows for significant modifications, leading to impressive power outputs when paired with aftermarket components.
The HKS Turbo Kit Overview
The HKS Turbo Kit is designed to maximize the performance of the 4G63 engine. This kit typically includes a larger turbocharger, upgraded intercooler, high-flow fuel injectors, and a performance exhaust system. The goal of the HKS Turbo Kit is to provide a substantial increase in horsepower and torque while maintaining reliability.
Stock vs. HKS Turbo Kit: Dyno Results
To understand the performance differences between the stock setup and the upgraded HKS Turbo Kit, we conducted a series of dyno tests. Below are the results showcasing the power gains achieved with the turbo upgrade.
- Stock 4G63 Engine: 190 horsepower, 205 lb-ft of torque
- Upgraded with HKS Turbo Kit: 280 horsepower, 300 lb-ft of torque
Power Gains Analysis
The results from the dyno clearly illustrate the advantages of upgrading to the HKS Turbo Kit. The increase of 90 horsepower and 95 lb-ft of torque demonstrates the effectiveness of the kit in enhancing the engine’s performance. This power boost not only improves acceleration but also enhances the overall driving experience.
Benefits of Upgrading to the HKS Turbo Kit
Upgrading to the HKS Turbo Kit offers several benefits beyond just power gains. These include:
- Improved Throttle Response: The larger turbocharger provides quicker spool times, resulting in enhanced throttle response.
- Better Heat Management: The upgraded intercooler helps to reduce intake temperatures, allowing for more efficient combustion.
- Increased Reliability: HKS components are designed for durability, ensuring that the engine can handle the increased power without compromising reliability.
- Enhanced Driving Experience: The overall performance improvement leads to a more enjoyable driving experience, especially during spirited driving or track use.
Considerations Before Upgrading
While the HKS Turbo Kit offers significant advantages, there are several considerations to keep in mind before proceeding with the upgrade:
- Cost: The HKS Turbo Kit and installation can be a significant investment.
- Supporting Modifications: Upgrading the turbo may require additional modifications, such as upgrading the fuel system and tuning the ECU.
- Potential for Increased Wear: Higher power outputs can lead to increased wear on engine components, necessitating regular maintenance and monitoring.
- Insurance and Legal Considerations: Modifications may affect insurance premiums and legality in certain regions.
Conclusion
The comparison between the stock 4G63 engine and the upgraded setup with the HKS Turbo Kit clearly shows that significant power gains can be achieved. With an increase of 90 horsepower and 95 lb-ft of torque, the HKS Turbo Kit transforms the driving experience, making it a worthy investment for those looking to enhance their vehicle’s performance. However, potential buyers should weigh the benefits against the costs and considerations before proceeding with the upgrade.
