Removing the Stock Turbocharger
Begin by removing the stock turbocharger from your Golf R. Follow these steps:
- Remove the engine cover by unscrewing the bolts.
- Disconnect the intake and exhaust pipes connected to the stock turbo.
- Remove the oil feed and drain lines from the stock turbo.
- Unbolt the turbo from the manifold and carefully remove it from the engine bay.
Installing the Precision PT5850 Turbo
Once the stock turbo is removed, it’s time to install the Precision PT5850 turbo. Follow these steps:
- Position the Precision PT5850 turbo onto the manifold.
- Secure the turbocharger with the bolts, ensuring they are tightened to the manufacturer’s specifications.
- Reconnect the oil feed and drain lines to the new turbo.
- Install the new downpipe, ensuring a tight fit.
- Connect the intercooler piping and secure with silicone couplers.
Connecting the Boost Controller
To manage the increased boost levels effectively, it’s essential to connect a boost controller. Here’s how:
- Locate a suitable position for the boost controller inside the cabin.
- Run the necessary wiring from the controller to the engine bay.
- Connect the boost controller to the turbocharger’s wastegate.
- Ensure all connections are secure and free from leaks.
Final Checks and Reassembly
Before starting the engine, it’s crucial to perform final checks:
- Double-check all connections, including oil lines, intercooler piping, and exhaust connections.
- Ensure that all bolts are torqued to the specified settings.
- Fill the engine with new oil and coolant as necessary.
Starting the Engine
With everything in place, it’s time to start the engine:
- Reconnect the battery.
- Turn the ignition to the “on” position without starting to prime the fuel system.
- Start the engine and allow it to idle for a few minutes.
- Check for any leaks or unusual noises during idle.
Tuning the Vehicle
After installation, tuning the vehicle is essential to optimize performance and ensure reliability:
- Use a tuning software compatible with the Golf R to adjust fuel maps and boost levels.
- Monitor engine parameters to ensure everything is functioning correctly.
- Consider a dyno session to measure horsepower gains and make necessary adjustments.
Conclusion
