The Mitsubishi Eclipse GST is a beloved platform among car enthusiasts, known for its potential to be modified into a powerful machine. With a budget of just $1,200, many would doubt the possibility of reaching 330 horsepower. However, through careful planning, strategic upgrades, and a bit of ingenuity, this goal can be achieved. In this article, we will explore the steps taken to build a $1,200 Eclipse GST that reached 330 hp.
Understanding the Mitsubishi Eclipse GST
The Mitsubishi Eclipse GST, produced in the late 1990s and early 2000s, features a turbocharged 2.0L inline-four engine known as the 4G63. This engine is renowned for its robust aftermarket support and tuning potential. With the right modifications, it can easily handle increased power outputs.
Setting the Budget
To achieve the target of 330 hp, it is crucial to set a clear budget. In this case, the entire build was capped at $1,200. This budget must cover parts, labor, and any unexpected expenses that may arise during the build process.
Budget Breakdown
- Engine upgrades: $600
- Turbocharger: $300
- Fuel system modifications: $200
- Miscellaneous parts: $100
Key Modifications for Power
To reach 330 hp, several key modifications were necessary. Each modification plays a critical role in enhancing performance and ensuring the engine can handle the increased power.
Upgrading the Turbocharger
The stock turbocharger on the Eclipse GST is capable but limited in power output. Upgrading to a larger turbocharger is essential for achieving higher horsepower. A popular choice among enthusiasts is the T28 turbo, which provides a significant increase in airflow and boost pressure.
Enhancing the Fuel System
To support the increased power from the turbocharger, the fuel system must also be upgraded. This includes installing larger fuel injectors and a higher-flow fuel pump. These components ensure the engine receives adequate fuel to match the increased air intake.
Improving Engine Management
A proper engine management system is vital for tuning the vehicle to its new specifications. Using a standalone engine management system or a quality ECU upgrade allows for precise tuning of fuel maps and ignition timing, maximizing power while maintaining reliability.
Supporting Modifications
In addition to the primary modifications aimed at increasing horsepower, several supporting modifications are necessary for the overall performance and reliability of the vehicle.
Exhaust System Upgrade
A free-flowing exhaust system is crucial for reducing back pressure and improving turbo response. Upgrading to a performance exhaust system ensures that exhaust gases exit the engine efficiently, contributing to overall power gains.
Intercooler Installation
Installing a larger intercooler helps to cool the intake air, which increases density and improves combustion efficiency. A front-mount intercooler is a popular choice that provides significant cooling benefits over the stock unit.
Tuning the Build
Once all modifications are installed, the final step is tuning the vehicle. This process ensures that the engine runs smoothly and efficiently at the new power levels. A professional tuner can help achieve the best results, ensuring that the vehicle is both powerful and reliable.
Real-World Testing and Results
After completing the build and tuning, it was time for real-world testing. The results were impressive, with the Eclipse GST reaching a peak output of 330 hp on the dyno. This achievement demonstrates the potential of the platform and the effectiveness of the modifications made within the budget.
Conclusion
Building a Mitsubishi Eclipse GST that reaches 330 hp on a $1,200 budget is both challenging and rewarding. With the right approach and modifications, it is possible to unlock the full potential of this iconic vehicle. The journey of this build showcases the creativity and determination of car enthusiasts in achieving their performance goals.
