Preparation
Before starting the installation, ensure you have a clean and organized workspace. Gather all tools and materials to avoid interruptions during the process. It’s also advisable to disconnect the battery to prevent any electrical issues.
Step 1: Remove the Stock Components
Begin by removing the stock intake system and exhaust manifold. This process involves the following:
- Remove the air intake duct.
- Disconnect the mass airflow sensor.
- Unbolt the throttle body and intake manifold.
- Remove the exhaust manifold by unbolting it from the engine block.
Step 2: Install the Turbo Manifold
Next, install the turbo manifold. Follow these steps:
- Clean the surface of the engine block where the manifold will sit.
- Place a new gasket on the engine block.
- Align the turbo manifold and bolt it in place, ensuring it is secured to the specified torque settings.
Step 3: Install the Turbocharger
With the manifold in place, you can now install the Greddy TD06SL2-20G turbocharger:
- Attach the turbocharger to the manifold using the provided bolts.
- Ensure the oil feed and return lines are securely connected to the turbo.
- Check for any leaks before proceeding.
Step 4: Install the Intercooler and Piping
The next step is to install the intercooler and associated piping:
- Mount the intercooler in a suitable location, usually in front of the radiator.
- Connect the piping from the turbo to the intercooler and from the intercooler to the throttle body.
- Use silicone couplers to ensure a secure fit.
Step 5: Install the Blow-off Valve
Installing the blow-off valve is crucial for preventing compressor surge:
- Choose a suitable location for the blow-off valve on the intake piping.
- Securely mount the valve and connect it to the vacuum source.
- Ensure all connections are tight to avoid boost leaks.
Step 6: Upgrade the Fuel System
To support the increased power, upgrading the fuel system is necessary:
- Replace the stock fuel pump with a higher-capacity unit.
- Install larger fuel injectors to ensure adequate fuel delivery.
- Check for proper fuel pressure to avoid any lean conditions.
Step 7: ECU Tuning
After completing the hardware installation, it’s essential to tune the ECU:
- Connect the ECU tuning software to your vehicle.
- Adjust the fuel maps and ignition timing to optimize performance.
- Monitor the air-fuel ratio to ensure the engine runs efficiently.
Step 8: Final Checks and Testing
Before hitting the road, perform a series of final checks:
- Inspect all connections for leaks.
- Ensure the oil and coolant levels are adequate.
- Start the engine and let it idle, monitoring for any unusual sounds.
- Take the car for a test drive, gradually increasing boost levels.
Conclusion
Installing a turbo kit on your Nissan 350Z can significantly enhance its performance. By following these steps carefully and ensuring proper tuning, you can achieve up to 380 horsepower with the Greddy TD06SL2-20G turbo kit. Always remember to consult with a professional if you are unsure about any part of the installation process.
