The Jeep Wrangler JL is a popular choice among off-road enthusiasts and those looking for a versatile vehicle. One of the most exciting modifications you can make to enhance its performance is the installation of a Hellcat-style turbocharger. This upgrade can provide over 60 horsepower gains, transforming your driving experience. In this article, we will walk you through the step-by-step installation process.
Tools and Materials Needed
- Hellcat-style turbocharger kit
- Socket set
- Wrenches
- Screwdrivers
- Torque wrench
- Intercooler piping
- Vacuum lines
- Oil feed and return lines
- Fuel injectors (if required)
- ECU tuning software
Preparation
Before starting the installation, ensure that you have all necessary tools and materials at hand. Additionally, park your Wrangler JL on a flat surface and disconnect the battery to prevent any electrical issues during the installation process.
Step 1: Remove the Stock Components
The first step in the installation process is to remove the stock components that will be replaced by the turbocharger. This includes the stock air intake system, exhaust manifold, and any other components that may obstruct the installation of the turbo.
1.1 Remove the Air Intake
Start by loosening the clamps and disconnecting the air intake from the throttle body. Carefully remove the air filter and intake tubing.
1.2 Detach the Exhaust Manifold
Next, unbolt the exhaust manifold from the engine block. Make sure to collect any gaskets or hardware for reuse or replacement later.
Step 2: Install the Turbocharger
With the stock components removed, you can now install the Hellcat-style turbocharger. Follow the manufacturer’s instructions for the specific turbo kit you are using.
2.1 Mount the Turbocharger
Position the turbocharger where the stock exhaust manifold was located. Use new gaskets to ensure a proper seal and bolt the turbocharger in place.
2.2 Connect the Exhaust and Intake
Connect the exhaust side of the turbo to the exhaust system. Then, attach the intake side to the new air intake system that comes with the turbo kit.
Step 3: Install Intercooler and Piping
The next step is to install the intercooler and the associated piping. This is crucial for ensuring that the air entering the engine is cooled, which helps improve performance.
3.1 Position the Intercooler
Find a suitable location for the intercooler, typically in front of the radiator. Secure it in place using the provided hardware.
3.2 Connect the Piping
Attach the intercooler piping from the turbocharger to the intercooler and then to the throttle body. Ensure all connections are tight and secure.
Step 4: Hook Up Oil Lines
To ensure proper lubrication of the turbocharger, you need to install the oil feed and return lines.
4.1 Install the Oil Feed Line
Connect the oil feed line from the engine to the turbocharger. Make sure to use a high-quality fitting to prevent leaks.
4.2 Connect the Oil Return Line
Next, connect the oil return line from the turbocharger back to the engine. Again, ensure all fittings are secure.
Step 5: Update the ECU
After all hardware is installed, it’s essential to update the ECU to accommodate the new turbocharger. Use the tuning software to adjust the fuel maps and timing to optimize performance.
Step 6: Reconnect the Battery and Start the Engine
With everything installed and the ECU updated, reconnect the battery. Start the engine and check for any leaks or issues. Allow the engine to idle for a few minutes before taking it for a test drive.
Conclusion
Installing a Hellcat-style turbocharger on your Wrangler JL can significantly enhance its performance, providing over 60 horsepower gains. By following these steps carefully, you can ensure a successful installation and enjoy the benefits of increased power and responsiveness.
