The H22 engine is a popular choice among car enthusiasts looking to build a powerful turbo setup. With its strong internals and high-revving capabilities, it can handle significant power increases when paired with the right components. In this article, we will explore the best turbo build setup for the H22 engine, focusing on Tial wastegates, 750cc injectors, and the MoTeC ECU.
Understanding the H22 Engine
The H22 engine, known for its performance in various Honda models, features a DOHC design and a displacement of 2.2 liters. This engine is capable of producing impressive horsepower and torque figures, making it an ideal candidate for turbocharging.
Key Components of the Turbo Build
- Tial Wastegates
- 750cc Injectors
- MoTeC ECU
Tial Wastegates
Tial wastegates are renowned for their reliability and performance. They help regulate exhaust flow to the turbocharger, ensuring optimal boost levels and preventing overboost conditions. Choosing the right size wastegate is crucial for achieving the desired performance.
750cc Injectors
When building a turbocharged engine, fuel delivery is critical. The 750cc injectors provide ample fuel flow to support higher horsepower levels. These injectors are capable of handling the increased fuel demands of a turbo setup, ensuring that the engine runs efficiently and safely.
MoTeC ECU
The MoTeC ECU is a top choice for tuning turbocharged engines. It offers advanced features that allow for precise control over fuel maps, ignition timing, and boost levels. With the MoTeC ECU, you can maximize the performance of your H22 turbo build while ensuring reliability.
Building the Turbo Setup
When assembling your H22 turbo build, it is essential to follow a systematic approach. Here are the key steps to consider:
- Select the right turbocharger for your goals.
- Install the Tial wastegate to manage boost pressure.
- Upgrade the fuel system with 750cc injectors.
- Set up the MoTeC ECU for optimal tuning.
- Ensure proper exhaust and intake routing.
Choosing the Right Turbocharger
The choice of turbocharger is crucial to the success of your build. Factors to consider include:
- Turbo size and type
- Boost pressure capabilities
- Response time and lag
- Compatibility with the H22 engine
Fuel System Upgrades
Upgrading the fuel system is necessary to support the increased power output. Consider the following components:
- High-flow fuel pump
- AN fittings and lines
- Fuel pressure regulator
Tuning Your Setup
After completing the installation of your turbo setup, tuning is critical for achieving the best performance. Proper tuning ensures that the engine runs smoothly and efficiently. Here are some tips:
- Use a wideband O2 sensor for accurate air-fuel ratio readings.
- Monitor boost levels during tuning.
- Adjust ignition timing for optimal performance.
Conclusion
Building a turbo setup for the H22 engine can yield impressive results when done correctly. By combining Tial wastegates, 750cc injectors, and a MoTeC ECU, you can create a powerful and reliable turbocharged engine.
