Installing a Garrett GT3586R turbocharger on your SR20DET engine can significantly enhance performance. This guide will take you through the entire process step-by-step, ensuring a successful installation.

Tools and Materials Needed

  • Garrett GT3586R Turbocharger
  • SR20DET Turbo Manifold
  • Wastegate
  • Oil Feed and Return Lines
  • Intercooler Piping
  • Silicone Hoses
  • Clamps
  • Gaskets
  • Wrenches and Sockets
  • Torque Wrench
  • Engine Oil
  • Coolant

Preparation Steps

Before starting the installation, it’s essential to prepare your workspace and gather all necessary tools and materials. Ensure your vehicle is parked on a level surface and that you have access to all parts of the engine.

Additionally, disconnect the battery to prevent any electrical issues during the installation process.

Removing the Old Turbocharger

Start by removing the old turbocharger from your SR20DET. Follow these steps:

  • Remove the intake pipe connected to the turbocharger.
  • Disconnect the oil feed line and oil return line.
  • Unbolt the turbocharger from the manifold.
  • Remove the wastegate if applicable.
  • Carefully take out the old turbocharger.

Installing the Garrett GT3586R Turbocharger

With the old turbo removed, you can now install the Garrett GT3586R. Follow these steps:

  • Place the new turbocharger on the manifold.
  • Secure it using the bolts, ensuring they are tightened to the manufacturer’s specifications.
  • Reconnect the wastegate if you are using one.
  • Attach the oil feed and return lines to the new turbo.
  • Ensure all connections are tight and leak-free.

Connecting the Intercooler and Intake

Next, you will need to connect the intercooler and intake piping:

  • Attach the intercooler piping to the outlet of the turbocharger.
  • Secure all hoses with clamps to prevent any boost leaks.
  • Connect the intake pipe to the turbo inlet.

Final Checks and Fluids

Before starting the engine, perform the following checks:

  • Inspect all connections for tightness.
  • Check for any potential leaks in the oil and coolant lines.
  • Ensure the intercooler piping is secure.
  • Fill the engine with fresh oil if necessary.
  • Check the coolant level and top up if needed.

Starting the Engine

Once everything is checked and secured, reconnect the battery and start the engine. Observe the following:

  • Listen for any unusual noises.
  • Check for leaks around the turbo and connections.
  • Monitor oil pressure and temperature.

Tuning Your SR20DET

After installation, it’s important to tune your SR20DET to ensure optimal performance with the new turbocharger. Consider the following:

  • Use a standalone engine management system or a tuned ECU.
  • Adjust fuel maps and ignition timing as necessary.
  • Monitor air-fuel ratios to avoid running lean.

Conclusion

Installing a Garrett GT3586R turbocharger on your SR20DET can significantly boost performance when done correctly. Follow this guide carefully, and ensure you take all necessary precautions for a successful installation.
