The 4G63 engine, known for its robust performance and tuning potential, is a popular choice among car enthusiasts looking to achieve high horsepower figures. Building a 500 horsepower 4G63 engine is an ambitious project that requires careful planning and budgeting. In this article, we will break down the costs associated with building a 4G63 to 500 hp, including parts, labor, and additional expenses.
Understanding the 4G63 Engine
The 4G63 is a 2.0-liter inline-four engine that was originally produced by Mitsubishi. It gained fame through its use in the Mitsubishi Eclipse and Eagle Talon models in the 1990s. Known for its turbocharged variants, the 4G63 has a strong aftermarket support, making it a prime candidate for performance builds.
Key Components for a 500 HP Build
- Engine Block
- Pistons and Rods
- Turbocharger
- Fuel System
- Engine Management System
- Exhaust System
- Cooling System
Engine Block
The foundation of your build is the engine block. For a 500 hp build, consider using a reinforced block to handle the increased power. Costs can vary significantly based on whether you choose a new block or a used one.
Pistons and Rods
High-performance pistons and rods are crucial for achieving the desired horsepower while maintaining reliability. Forged components are recommended for their strength and durability under high-stress conditions.
Turbocharger
A turbocharger is essential for boosting horsepower. Selecting the right turbo that matches your power goals and engine characteristics is key. Larger turbos can provide more power but may introduce lag.
Fuel System
To support 500 hp, an upgraded fuel system is necessary. This includes larger fuel injectors, a high-flow fuel pump, and possibly a fuel pressure regulator. Proper fuel delivery is critical for performance and engine safety.
Engine Management System
An aftermarket engine management system allows for precise tuning of your engine. This is vital for optimizing performance and ensuring that the engine runs efficiently and reliably at high power levels.
Exhaust System
A high-performance exhaust system will help reduce back pressure and improve exhaust flow, which is essential for maximizing power output. Consider upgrading to a larger diameter exhaust and high-flow catalytic converter.
Cooling System
With increased power comes increased heat. An efficient cooling system, including an upgraded radiator and intercooler, is necessary to keep engine temperatures in check during high-performance driving.
Cost Breakdown
Now that we’ve outlined the key components, let’s break down the costs associated with each part of the build.
- Engine Block: $500 – $2,000
- Pistons and Rods: $600 – $1,200
- Turbocharger: $800 – $2,500
- Fuel System: $500 – $1,500
- Engine Management System: $500 – $1,500
- Exhaust System: $300 – $1,000
- Cooling System: $300 – $1,000
Labor Costs
If you are not performing the build yourself, labor costs can add significantly to your budget. Labor rates vary by location and shop, but expect to pay anywhere from $70 to $150 per hour. A complete build could take anywhere from 20 to 40 hours, depending on the complexity of the work.
Additional Expenses
Beyond the core components and labor, there are other costs to consider:
- Tuning: $300 – $1,000
- Miscellaneous Parts (gaskets, fluids, etc.): $200 – $500
- Dyno Testing: $100 – $300
- Upgrades to Transmission and Drivetrain: $500 – $2,000
Total Estimated Cost
When you add everything up, a 500 hp build for a 4G63 engine can range anywhere from $5,000 to $15,000 or more, depending on the choices you make regarding parts and labor. Here’s a rough estimate:
- Low-End Estimate: $5,000
- Mid-Range Estimate: $10,000
- High-End Estimate: $15,000+
Conclusion
Building a 500 hp 4G63 engine is a significant investment, but for many enthusiasts, the performance gains and satisfaction of a well-executed build make it worthwhile. By carefully planning your budget and selecting the right components, you can achieve your horsepower goals while keeping costs under control.
