The 4G63 engine, known for its robust performance and tuning potential, has become a favorite among automotive enthusiasts looking to achieve high horsepower. In this article, we will break down the costs associated with building a 4G63 engine equipped with forged internals, an upgraded fuel system, and the capability to produce over 650 horsepower.
Understanding the 4G63 Engine
The 4G63 is a 2.0L inline-four engine that originated from Mitsubishi. It has gained a reputation for its performance in various applications, particularly in the Mitsubishi Eclipse and Lancer Evolution models. Its sturdy design allows for significant power upgrades, making it a popular choice for tuners.
Key Components for a 650+ HP Build
- Forged Internals
- Upgraded Fuel System
- Turbocharger
- ECU Tuning
- Exhaust System
1. Forged Internals
Forged internals are crucial for handling the increased power levels. This includes forged pistons, connecting rods, and a crankshaft. The cost for these components can vary widely based on brand and specifications.
- Forged Pistons: $500 – $1,200
- Forged Connecting Rods: $400 – $800
- Forged Crankshaft: $600 – $1,200
2. Upgraded Fuel System
A high-performance fuel system is essential for delivering the necessary fuel to support 650+ horsepower. This includes larger fuel injectors, a high-flow fuel pump, and upgraded fuel lines.
- Larger Fuel Injectors: $300 – $600
- High-Flow Fuel Pump: $150 – $300
- Fuel Lines and Fittings: $100 – $250
3. Turbocharger
Upgrading the turbocharger is one of the most significant factors in achieving higher horsepower. A larger turbo can provide the necessary boost to reach the desired power levels.
- Performance Turbocharger: $1,000 – $2,500
- Turbo Accessories (wastegate, etc.): $300 – $700
4. ECU Tuning
ECU tuning is vital for optimizing the engine’s performance and ensuring that all components work harmoniously. This process can be done via standalone systems or reprogramming the stock ECU.
- Standalone ECU: $500 – $1,500
- Reflash or Tune: $300 – $800
5. Exhaust System
An upgraded exhaust system is necessary to reduce back pressure and improve airflow. This includes a performance downpipe and cat-back exhaust system.
- Performance Downpipe: $200 – $600
- Cat-Back Exhaust: $300 – $800
Total Cost Breakdown
Now that we have explored the key components, let’s summarize the total estimated costs for building a 4G63 engine capable of producing 650+ horsepower.
- Forged Internals: $1,500 – $3,200
- Upgraded Fuel System: $550 – $1,150
- Turbocharger: $1,300 – $3,200
- ECU Tuning: $800 – $2,300
- Exhaust System: $500 – $1,400
Conclusion
Building a 4G63 engine with forged internals, an upgraded fuel system, and the capability to produce over 650 horsepower is a significant investment. The total cost can range from approximately $4,650 to $11,250, depending on the choices made for each component. Careful planning and budgeting will ensure a successful build that meets your performance goals.
