Tools and Materials Needed
- Precision 6266 turbocharger
- Turbo manifold
- Wastegate
- Intercooler
- Silicone couplers
- Boost controller
- Fuel injectors
- Fuel pump
- Oil feed and return lines
- Gaskets
- Basic hand tools (sockets, wrenches, pliers)
- Torque wrench

Preparation Steps
Before beginning the installation, ensure your workspace is clean and organized. Gather all tools and materials to minimize downtime during the process.
Disconnect the battery to prevent any electrical issues while working on your vehicle. It’s also advisable to drain the coolant and engine oil to avoid spills during the installation.
Removing the Old Turbo
Start by removing the air intake system and any components obstructing access to the turbocharger. This includes the intake manifold and any associated piping.
Next, disconnect the oil feed and return lines, followed by the wastegate actuator. Make sure to label any hoses or wires for easy reinstallation.
Once everything is disconnected, remove the bolts securing the old turbo to the manifold. Carefully lift the turbo out of its position and set it aside.
Installing the Precision 6266 Turbo
Begin by placing the new Precision 6266 turbocharger onto the manifold. Ensure it is aligned correctly with the mounting points.
Secure the turbo with the appropriate bolts, tightening them to the manufacturer’s specifications using a torque wrench.
Reconnect the oil feed and return lines, ensuring there are no leaks. Install the wastegate actuator and any other necessary components that were removed during the disassembly.
Upgrading Supporting Components
To maximize the performance of your new turbo, consider upgrading supporting components such as the intercooler, fuel injectors, and fuel pump.
Intercooler Installation
Remove the old intercooler and replace it with a high-performance unit that can handle increased boost levels. Ensure all piping is securely connected and sealed with silicone couplers.
Fuel System Upgrade
Install larger fuel injectors and a high-flow fuel pump to support the increased fuel demands of the Precision 6266. Make sure to recalibrate your engine management system to accommodate these changes.
Final Steps and Testing
After all components are installed, double-check all connections and ensure everything is secure. Reconnect the battery and refill the coolant and oil as necessary.
Start the engine and allow it to idle for a few minutes. Check for any leaks and listen for unusual noises. Once satisfied, take the car for a test drive to evaluate performance.
Monitor the boost levels and ensure the vehicle is running smoothly. If everything checks out, you have successfully upgraded your B5 S4 with a Precision 6266 turbocharger!
Conclusion
Upgrading to a Precision 6266 turbocharger is a great way to enhance the performance of your B5 S4. By following these steps, you can achieve reliable 400+ horsepower and enjoy an exhilarating driving experience.
