The 4G63 engine is a popular choice among drag racing enthusiasts due to its robust design and potential for high power output. This article explores the key aspects of building a 4G63 turbo engine specifically for drag racing, focusing on power levels, safety, and durability.
Understanding the 4G63 Engine
The 4G63 is a 2.0-liter inline-four engine that originated from Mitsubishi. It has gained fame for its performance capabilities, especially when turbocharged. This engine has been used in various models, including the Mitsubishi Eclipse and Eagle Talon.
- 2.0-liter inline-four configuration
- Available in naturally aspirated and turbocharged variants
- Known for its strong aftermarket support
Power Levels for Drag Racing
When building a 4G63 turbo engine for drag racing, achieving optimal power levels is crucial. The target power output can vary based on the specific racing class and regulations.
Target Power Outputs
For a competitive drag racing setup, the following power levels are commonly targeted:
- 400-500 horsepower for entry-level classes
- 600-800 horsepower for intermediate classes
- 1000+ horsepower for professional classes
Boost Levels
Boost levels play a significant role in achieving desired power outputs. Consider the following:
- Stock turbo: 15-20 psi
- Aftermarket turbo: 25-30 psi
- High-performance setups: 30+ psi
Safety Considerations
Building a high-power 4G63 engine for drag racing comes with inherent risks. Safety should always be a top priority. Here are essential safety measures to consider:
- Install a roll cage to protect the driver in case of a crash.
- Use a fire suppression system to mitigate fire risks.
- Ensure proper harnesses and racing seats for driver safety.
Durability and Reliability
Durability is vital for any drag racing engine. The 4G63 can handle significant power, but specific modifications are necessary to ensure reliability under extreme conditions.
Essential Modifications
To enhance the durability of the 4G63 engine, consider the following modifications:
- Upgrade to forged internals (pistons, rods, and crankshaft).
- Install a high-performance intercooler to reduce intake temperatures.
- Utilize a quality oil management system to maintain lubrication under stress.
Cooling Systems
Proper cooling is essential for maintaining engine performance and longevity. Consider these options:
- Upgrade to a larger radiator for improved heat dissipation.
- Install an oil cooler to maintain optimal oil temperatures.
- Consider water/methanol injection for additional cooling.
Conclusion
Building a 4G63 turbo engine for drag racing requires careful consideration of power levels, safety, and durability. By focusing on these aspects, you can create a reliable and competitive drag racing machine. Always prioritize safety and ensure that your modifications align with racing regulations.
