Preparation Steps
Before starting the installation, ensure that you have all the necessary tools and components. It is also essential to prepare your workspace to facilitate a smooth build process.
1. Gather Your Tools
Collect all tools listed in the materials section. Organizing them will save time during the installation.
2. Prepare the Engine Bay
Clear out the engine bay of any unnecessary components. This includes removing the intake manifold and any other parts that may obstruct the turbo installation.
Turbocharger Installation
The turbocharger is the heart of your build. Proper installation is crucial for performance and reliability.
1. Install the Turbocharger
Begin by mounting the Precision turbocharger to the exhaust manifold. Ensure that the gasket is in place to prevent leaks.
2. Connect Oil Lines
Install the oil feed and return lines to the turbo. Use thread sealant to ensure a tight fit and prevent leaks.
Intercooler and Piping Installation
The intercooler is essential for cooling the intake air, improving performance. Proper routing of the piping is key.
1. Mount the Intercooler
Position the Greddy intercooler in front of the radiator. Use brackets to secure it in place.
2. Install Piping
Connect the piping from the turbo to the intercooler and from the intercooler to the intake manifold. Use silicone couplers to ensure flexibility and a secure fit.
Wastegate and Blow-off Valve Installation
Properly installing the wastegate and blow-off valve is critical for controlling boost pressure.
1. Install the Wastegate
Mount the Tial wastegate to the designated spot on the manifold. Ensure it is securely fastened and connected to the vacuum source.
2. Connect the Blow-off Valve
Install the Tial blow-off valve on the piping leading to the intake. This will prevent compressor surge and maintain boost pressure.
Fuel System Upgrades
To support the increased power from the turbo, upgrading the fuel system is necessary.
1. Upgrade Fuel Injectors
Install larger fuel injectors to provide the necessary fuel for the turbocharged setup. Ensure they are compatible with your engine management system.
2. Install a Fuel Management System
Implement a fuel management system to tune your engine for optimal performance. This is crucial for maximizing the benefits of the turbo build.
Final Checks and Testing
After completing the installation, it’s essential to perform final checks before starting the engine.
1. Check All Connections
Inspect all connections, including oil lines, piping, and vacuum hoses. Ensure everything is secure and leak-free.
2. Start the Engine
Start the engine and monitor for any unusual noises or leaks. Allow the engine to warm up and check the boost gauge for proper readings.
Conclusion
Building a turbocharged H22 engine is a rewarding experience that can significantly enhance performance. By following this step-by-step guide and using quality components from Greddy, Precision, and Tial, you can achieve a successful installation and enjoy the benefits of your hard work.
