How to Reach 300 Hp in Your 1g Eclipse: Best Forced Induction Setup Under $3,000

by

The 1G Mitsubishi Eclipse is a beloved platform for car enthusiasts looking to achieve impressive power numbers without breaking the bank. With the right forced induction setup, reaching 300 horsepower is entirely feasible for under $3,000. This article will guide you through the best components and strategies to maximize your 1G Eclipse’s performance.

Understanding Forced Induction

Forced induction refers to the process of forcing more air into the engine’s combustion chamber, allowing for more fuel to be burned and, consequently, more power to be produced. The two main types of forced induction are supercharging and turbocharging. For the 1G Eclipse, turbocharging is the preferred method due to its efficiency and effectiveness.

Choosing the Right Turbocharger

When selecting a turbocharger for your 1G Eclipse, consider the following factors:

  • Size: A turbo that is too large can cause lag, while one that is too small may not provide enough boost.
  • Type: Look for a journal bearing or ball bearing turbo; ball bearing turbos typically spool faster.
  • Brand: Reputable brands such as Garrett, Holset, and Precision offer reliable options.
  • Garrett GT28RS
  • Precision 5858
  • Holset HX35

Supporting Modifications

To ensure your engine can handle the added boost, several supporting modifications are essential:

  • Fuel System Upgrade: Upgrade to a higher-flow fuel pump and larger fuel injectors (around 550cc).
  • ECU Tuning: A proper tune is critical for maximizing performance and preventing engine damage.
  • Intercooler: Install a front-mount intercooler to reduce intake temperatures.
  • Exhaust System: Upgrade to a 3-inch exhaust system for improved airflow.

Budget Breakdown

Here’s a breakdown of estimated costs for each component needed to reach 300 hp:

  • Turbocharger: $800 – $1,200
  • Fuel Pump: $100 – $200
  • Fuel Injectors: $200 – $300
  • Intercooler: $200 – $400
  • Exhaust System: $300 – $500
  • ECU Tuning: $300 – $500

Installation Tips

Installing these components can be a challenging task. Here are some tips to help you through the process:

  • Research: Familiarize yourself with the installation process for each component.
  • Tools: Ensure you have the necessary tools, including wrenches, sockets, and a boost gauge.
  • Help: Don’t hesitate to ask for help from experienced friends or professionals.
  • Patience: Take your time to avoid mistakes that could lead to costly repairs.

Final Thoughts

Reaching 300 hp in your 1G Eclipse is an achievable goal with the right forced induction setup and supporting modifications. By carefully selecting your turbocharger and components, you can create a powerful and reliable setup that enhances your driving experience. Remember to budget wisely and consider professional help for installation and tuning to ensure optimal performance.
