Preparation Steps
Before starting the installation, ensure your workspace is clean and organized. Gather all the tools and materials listed above. It’s essential to have a clear understanding of the installation process to avoid any mistakes.
1. Disconnect the Battery
Safety is paramount. Begin by disconnecting the negative terminal of the battery to prevent any electrical shorts during installation.
2. Lift the Vehicle
Using a jack, lift the front of your Lexus IS and secure it with jack stands. This will provide better access to the engine bay and undercarriage.
Removing the Stock Components
To install the Greddy Turbo Kit, you must first remove several stock components. This process requires attention to detail to ensure everything is done correctly.
1. Remove the Intake System
Start by removing the air intake system. Disconnect any sensors and hoses connected to the intake. Unscrew the clamps and carefully remove the intake tubing.
2. Remove the Exhaust Manifold
Next, you will need to remove the exhaust manifold. Disconnect the exhaust piping and unbolt the manifold from the engine. Be cautious, as some bolts may be stubborn due to heat exposure.
Installing the Greddy Turbo Kit
With the stock components removed, you can now install the Greddy Turbo Kit. Follow the instructions provided with the kit carefully.
1. Install the Turbocharger
Begin by mounting the turbocharger onto the exhaust manifold. Ensure all gaskets are in place, and torque the bolts to the manufacturer’s specifications.
2. Connect the Intercooler
Install the intercooler in the front of the vehicle. Connect the intercooler piping from the turbocharger to the intercooler and then to the intake manifold. Secure all clamps tightly.
3. Install the Oil and Coolant Lines
Connect the oil feed and return lines to the turbocharger. Ensure there are no leaks by double-checking all connections. Next, connect the coolant lines to help maintain the turbo’s temperature.
Final Steps
Once the turbo kit is installed, you will need to reassemble any components you removed earlier. Take your time to ensure everything is correctly reinstalled.
1. Reconnect the Intake System
Reinstall the air intake system, ensuring all sensors and hoses are reconnected. Secure all clamps and check for any potential air leaks.
2. Lower the Vehicle
Carefully lower the vehicle back to the ground and reconnect the battery. Make sure all tools and materials are removed from the engine bay.
Testing the Installation
Before taking your Lexus IS for a drive, it’s crucial to test the installation. Start the engine and let it idle for a few minutes. Check for any leaks and listen for any unusual noises.
1. Check for Leaks
Inspect all connections for oil, coolant, and boost leaks. If you notice any leaks, address them immediately before proceeding.
2. Take a Test Drive
Once everything checks out, take your Lexus IS for a test drive. Monitor the performance and ensure the turbo is functioning correctly. Enjoy your new power gains!

Installing a Greddy Turbo Kit on your Lexus IS can provide substantial performance improvements. By following this step-by-step guide, you can achieve over 50 horsepower gains and enhance your driving experience.
