- Install the new oil feed and drain lines, making sure they are properly routed and secured.
- Connect the exhaust downpipe to the turbo.
Step 3: Connect the Intercooler and Piping
Next, you will need to connect the intercooler and the associated piping:
- Install the intercooler in its designated location.
- Connect the piping from the turbo to the intercooler.
- Ensure all clamps are tight to prevent boost leaks.
Step 4: Install the Boost Controller
To manage the increased boost levels, install a boost controller:
- Follow the manufacturer’s instructions for installation.
- Connect it to the vacuum source and the wastegate actuator.
Step 5: Final Checks and Reassembly
Before reassembling everything, double-check all connections and fittings:
- Ensure all bolts are tightened to spec.
- Check for any potential leaks in the oil and boost systems.
- Reconnect the battery.
Once verified, reassemble any components that were removed during the installation process.
Post-Installation Tuning
After the installation is complete, it’s crucial to tune your vehicle to optimize performance. A professional tune will help ensure that the engine runs efficiently and safely with the new turbo setup.
