How Much Horsepower Can You Expect from a 2g Eclipse Turbo Conversion?

The 2G Eclipse, produced by Mitsubishi and sold under the Eagle and Plymouth brands, has garnered a dedicated following among car enthusiasts. One of the most popular modifications for these vehicles is the turbo conversion. This article explores how much horsepower you can expect from a 2G Eclipse turbo conversion.

Understanding the 2G Eclipse

The second generation of the Mitsubishi Eclipse was produced from 1995 to 1999. It came with various engine options, including the naturally aspirated 2.0L inline-4 and the more powerful 2.0L turbocharged engine. The turbo model, known as the GS-T or GSX, already had a significant horsepower advantage over its non-turbo counterparts.

What is a Turbo Conversion?

A turbo conversion involves adding a turbocharger to a naturally aspirated engine. This modification increases the engine’s airflow, allowing for more fuel to be burned, resulting in increased power output. For the 2G Eclipse, this means transforming the non-turbo engine into a more powerful turbocharged version.

Expected Horsepower Gains

The horsepower gains from a turbo conversion on a 2G Eclipse can vary significantly based on several factors, including the quality of the parts used, the tuning process, and supporting modifications. Here’s a breakdown of what you can typically expect:

  • Stock 2.0L Non-Turbo Engine: Approximately 92-100 horsepower
  • Basic Turbo Conversion: 200-250 horsepower
  • Upgraded Turbo and Supporting Mods: 250-300 horsepower
  • High-Performance Build: 300+ horsepower

Factors Influencing Horsepower Output

Several factors can influence the final horsepower output after a turbo conversion. Understanding these can help you achieve your desired performance goals.

1. Turbocharger Selection

The choice of turbocharger plays a crucial role in the overall performance. A larger turbo can provide more power but may introduce turbo lag, while a smaller turbo can spool quickly but may limit peak power.

2. Engine Management and Tuning

Proper tuning is essential to maximize horsepower gains. An aftermarket engine management system or a professional tune can ensure that the engine runs efficiently and safely with the added boost.

3. Supporting Modifications

To handle the increased power, supporting modifications are often necessary. This may include upgraded fuel injectors, a high-flow fuel pump, intercoolers, and exhaust systems. Each of these components can contribute to increased horsepower.

4. Engine Condition

The condition of the engine itself is critical. A well-maintained engine will handle the added stress of a turbo conversion better than one that is worn or damaged.

Common Turbo Conversion Kits

There are several turbo conversion kits available for the 2G Eclipse. These kits typically include the necessary components for a successful conversion, such as the turbocharger, manifold, and intercooler. Here are some popular options:

  • FP 68HTA Turbo Kit
  • Garrett GT28R Turbo Kit
  • JMF Fabrications Turbo Kit
  • Revhard Turbo Kit

Conclusion

A turbo conversion on a 2G Eclipse can significantly increase horsepower, providing an exhilarating driving experience. With the right components and tuning, enthusiasts can expect to see gains ranging from 200 to over 300 horsepower. As with any modification, careful planning and execution are essential to achieve the best results.
