by

The Lexus IS is a popular choice for car enthusiasts looking to enhance performance. One of the most effective ways to achieve significant horsepower gains is through a turbocharger installation. In this guide, we will walk you through the step-by-step process of installing a turbocharger on your Lexus IS, aiming for an impressive increase of 100+ horsepower for around $3,500.

Understanding Turbochargers

A turbocharger is a device that forces more air into the engine, allowing for more fuel to be burned and increasing power output. This section will cover the basics of how turbochargers work and their benefits.

  • Increased horsepower and torque
  • Improved engine efficiency
  • Enhanced driving experience

Tools and Materials Needed

Before starting the installation, gather all necessary tools and materials to ensure a smooth process. Here’s what you’ll need:

  • Turbocharger kit
  • Wrenches and sockets
  • Screwdrivers
  • Torque wrench
  • Oil and coolant
  • Vacuum pump
  • Intercooler
  • Fuel management system

Preparation Steps

Before diving into the installation, it’s crucial to prepare your vehicle and workspace. Follow these steps:

  • Park the Lexus IS on a level surface.
  • Disconnect the battery to prevent electrical issues.
  • Remove any existing intake components.
  • Drain engine oil and coolant.

Step-by-Step Installation Process

Step 1: Remove the Exhaust Manifold

Begin by removing the exhaust manifold to make space for the turbocharger. This involves:

  • Unbolting the exhaust pipes from the manifold.
  • Removing the manifold bolts.
  • Carefully lifting the manifold off the engine.

Step 2: Install the Turbocharger

With the manifold removed, it’s time to install the turbocharger. Follow these steps:

  • Position the turbocharger onto the mounting points.
  • Secure the turbocharger with the provided bolts.
  • Connect the oil feed line to the turbo.

Step 3: Install the Intercooler

The intercooler is essential for cooling the air before it enters the engine. To install it:

  • Mount the intercooler in front of the radiator.
  • Connect the piping from the turbo to the intercooler.
  • Ensure all connections are tight and secure.

Step 4: Upgrade Fuel System

To support the increased airflow, upgrading the fuel system is necessary. This includes:

  • Installing larger fuel injectors.
  • Upgrading the fuel pump.
  • Connecting a fuel management system to optimize performance.

Step 5: Reassemble and Connect

Once all components are installed, reassemble any removed parts and connect necessary hoses:

  • Reattach the exhaust system.
  • Reconnect the battery.
  • Double-check all connections and fittings.

Final Checks and Testing

Before taking your Lexus IS for a test drive, perform the following checks:

  • Check for any leaks in the oil and coolant systems.
  • Ensure all electrical connections are secure.
  • Start the engine and listen for any unusual noises.

Conclusion

Installing a turbocharger on your Lexus IS can lead to significant performance gains and enhance your driving experience. By following this step-by-step guide, you can achieve over 100 horsepower increase for around $3,500. Enjoy your new power and drive safely!
