The Mitsubishi Evo is renowned for its performance, handling, and tuning potential. One of the most significant upgrades enthusiasts consider is the transition to a forged internal engine. This upgrade can yield substantial power gains, but it also comes with costs and considerations that need to be carefully evaluated.
Understanding Forged Internal Engines
Forged internal engines are built using forged components, which are stronger and more durable than their cast counterparts. This strength allows for higher levels of boost and power without compromising reliability. Key components that are often forged include:
- Forged pistons
- Forged connecting rods
- Forged crankshafts
These components can withstand the extreme conditions of high-performance engines, making them ideal for those looking to push their Mitsubishi Evo to the limits.
Power Gains from Upgrading
Upgrading to a forged internal engine can lead to significant power gains. Depending on the specific components used and the tuning of the engine, power increases can range from:
- 100 to 200 horsepower over stock
- Improved torque delivery across the RPM range
- Enhanced throttle response and overall drivability
These gains are particularly noticeable in high-boost applications, where the forged internals can handle the increased pressure without failure.
Cost Considerations
While the performance benefits are clear, the costs associated with upgrading to a forged internal engine can be substantial. Key cost factors include:
- Cost of forged components: Expect to pay between $1,500 and $4,000 for high-quality parts.
- Labor costs: Installation can range from $1,000 to $3,000 depending on the shop and complexity of the build.
- Tuning costs: Proper tuning is essential and can add another $500 to $1,500.
Overall, you might be looking at a total investment of $3,000 to $8,000 or more, depending on the specifics of your build and the level of performance you desire.
Additional Considerations
Before committing to a forged internal engine upgrade, there are several important factors to consider:
- Current engine condition: Ensure your base engine is in good shape to support the upgrade.
- Supporting modifications: Upgrading the engine may require additional modifications, such as improved fuel systems, intercoolers, and exhaust systems.
- Reliability vs. performance: Higher power levels can affect the longevity of other components in the vehicle.
Understanding these factors will help you make an informed decision about whether this upgrade is right for your Mitsubishi Evo.
Conclusion
Upgrading to a forged internal engine can provide significant power gains for your Mitsubishi Evo, transforming it into a high-performance machine. However, the costs associated with this upgrade can be considerable, and careful consideration of your entire build is essential. Whether you are a weekend racer or a dedicated enthusiast, investing in a forged engine can yield impressive results when done correctly.
