  • Turbo kit (including turbo, manifold, and piping)
  • TurboSmart wastegate
  • TurboSmart boost controller
  • Silicone couplers
  • Clamps
  • Heat wrap (optional)
  • Gasket maker

Preparation Steps

Preparation is key to a successful installation. Follow these steps to prepare your IS300:

  • Disconnect the battery to prevent electrical issues.
  • Remove the engine cover for better access.
  • Drain the coolant to avoid spills during installation.
  • Remove the intake manifold for easier turbo placement.

Installing the Turbo Manifold

The turbo manifold is the foundation of your turbo setup. Follow these steps for installation:

  • Align the turbo manifold with the engine block.
  • Use new gaskets to ensure a proper seal.
  • Tighten the bolts to the manufacturer’s specified torque settings.
  • Check for any leaks or misalignments before proceeding.

Mounting the Turbo

Once the manifold is secured, it’s time to mount the turbocharger:

  • Place the turbo onto the manifold, ensuring it fits snugly.
  • Secure the turbo with the provided bolts.
  • Connect the oil feed line to the turbo.
  • Attach the oil drain line, ensuring it slopes downwards for proper drainage.

Installing the TurboSmart Wastegate

The wastegate is critical for controlling boost pressure. Here’s how to install it:

  • Locate the appropriate mounting point on the turbo manifold.
  • Attach the TurboSmart wastegate using the supplied hardware.
  • Connect the vacuum line to the wastegate actuator.
  • Ensure all connections are tight and leak-free.

Installing the TurboSmart Boost Controller

To manage boost levels effectively, install the TurboSmart boost controller:

  • Choose a suitable location for the boost controller inside the cabin.
  • Run the necessary wiring and vacuum lines from the engine bay to the boost controller.
  • Connect the boost controller to the wastegate and intake manifold.
  • Follow the manufacturer’s instructions to calibrate the boost settings.

Connecting the Intake and Exhaust

With the turbo and wastegate installed, it’s time to connect the intake and exhaust systems:

  • Attach the intake piping to the turbo inlet.
  • Secure all connections with clamps.
  • Connect the exhaust piping to the turbo outlet.
  • Ensure all components are properly aligned and secured.

Final Checks and Reassembly

Before starting the engine, perform the following checks:

  • Inspect all connections for leaks or loose fittings.
  • Reinstall the intake manifold and engine cover.
  • Refill the coolant system.
  • Reconnect the battery.

Starting the Engine

With everything reassembled, it’s time to start your IS300:

  • Turn the key to the “on” position and check for any warning lights.
  • Start the engine and let it idle for a few minutes.
  • Monitor the oil pressure and coolant temperature.
  • Check for any leaks around the turbo and wastegate.

Tuning and Testing

After ensuring everything is functioning correctly, it’s important to tune your vehicle:

  • Use a tuning software compatible with your ECU.
  • Adjust the fuel maps and ignition timing as needed.
  • Test drive the vehicle to assess performance and boost levels.
  • Make further adjustments as required for optimal performance.

Conclusion

Installing a turbo kit on your IS300 can significantly enhance its performance. By following this step-by-step guide, you can successfully install a TurboSmart wastegate and boost controller, ensuring your vehicle runs efficiently and powerfully. Always remember to tune your vehicle properly to maximize your turbo setup’s potential.
