Upgrading your 4G63 engine to reach 350 horsepower can be a thrilling project, especially when done on a budget. This guide will walk you through the steps to achieve this goal using Tial wastegates, which are known for their reliability and performance. Let’s dive into the essential components and modifications needed for a successful turbo upgrade.
Understanding the 4G63 Engine
The 4G63 engine, a popular choice among car enthusiasts, is a 2.0L inline-4 engine that has been used in various Mitsubishi models. With the right modifications, this engine can produce impressive power levels. Before starting your upgrade, it’s essential to understand the engine’s capabilities and limitations.
Key Components for the Upgrade
- Turbocharger: Selecting the right turbocharger is crucial. Look for a turbo that can support 350 hp output.
- Fuel System: Upgrading the fuel injectors and pump is necessary to ensure adequate fuel delivery.
- ECU Tuning: A proper tune is required to optimize performance and ensure engine safety.
- Exhaust System: A high-flow exhaust will help reduce back pressure and improve turbo efficiency.
- Intercooler: An upgraded intercooler will help lower intake temperatures and increase power.
- Wastegate: Tial wastegates are an excellent choice for controlling boost pressure effectively.
Step-by-Step Upgrade Process
1. Turbocharger Selection
Choose a turbocharger that can provide the airflow necessary for 350 hp. Popular options include the Holset HX35 or the Garrett GT30. Make sure to consider the compressor and turbine sizes to match your engine’s requirements.
2. Upgrading the Fuel System
Install larger fuel injectors, typically 550cc or more, to accommodate the increased fuel demand. Upgrading the fuel pump to a higher flow rate model will also ensure that you have enough fuel pressure during high-performance conditions.
3. ECU Tuning
A proper ECU tune is essential for maximizing performance and ensuring engine longevity. Consider using a standalone ECU or a piggyback system that allows for custom tuning to match your specific setup.
4. Exhaust System Upgrade
Replace the stock exhaust manifold with a high-performance manifold designed for turbo applications. Additionally, install a 3-inch downpipe and cat-back exhaust system to reduce back pressure and improve turbo spool time.
5. Intercooler Installation
Install a front-mount intercooler to improve air density and reduce intake temperatures. This will help prevent knock and allow for more aggressive tuning.
6. Installing Tial Wastegates
Tial wastegates are known for their durability and precise boost control. Install the wastegate on the turbo manifold, ensuring proper plumbing to the boost source. Adjust the spring pressure according to your desired boost levels.
Testing and Fine-Tuning
After completing the installation, it’s crucial to test the setup thoroughly. Monitor boost levels, air-fuel ratios, and engine temperatures. Fine-tune the ECU to achieve optimal performance while ensuring reliability.
Conclusion
Reaching 350 hp with a budget-friendly 4G63 turbo upgrade using Tial wastegates is achievable with the right components and tuning. By following the steps outlined in this guide, you can enjoy the thrill of enhanced performance while staying within your budget. Always remember to prioritize safety and reliability in your modifications.
