  • Screwdrivers
  • Torque wrench
  • Engine hoist
  • RB20DET engine kit
  • Turbocharger
  • Exhaust manifold
  • Fuel pump upgrade
  • Intercooler and piping
  • ECU tuning software

Step 1: Preparing the Vehicle

Begin by preparing your vehicle for the engine swap. This includes removing the old engine and any unnecessary components.

  • Disconnect the battery.
  • Drain all fluids (oil, coolant, etc.).
  • Remove the old engine and transmission.
  • Clean the engine bay to ensure a smooth installation.

Step 2: Installing the RB20DET Engine

  • Attach the RB20DET engine to the hoist.
  • Carefully lower the engine into place.
  • Align the engine mounts with the chassis.
  • Secure the engine with bolts, ensuring they are torqued to specifications.

Step 3: Connecting the Turbocharger

Once the engine is secured, the next step is to connect the turbocharger. This process involves several key components that must be installed correctly for optimal performance.

  • Install the exhaust manifold to the engine.
  • Attach the turbocharger to the exhaust manifold.
  • Connect the wastegate and ensure it is functioning properly.
  • Install the intake piping and connect it to the turbocharger.
  • Ensure all clamps are tight and secure.

Step 4: Fuel System Upgrade

To support the increased power from the turbocharged engine, an upgrade to the fuel system is necessary. This step is crucial for maintaining engine performance and reliability.

  • Replace the stock fuel pump with a higher flow model.
  • Install larger fuel injectors compatible with the RB20DET.
  • Ensure the fuel lines are in good condition and properly connected.

Step 5: Intercooler Installation

An intercooler is essential for reducing the temperature of the compressed air from the turbocharger. This installation will help improve engine efficiency and performance.

  • Choose an appropriate intercooler for your setup.
  • Mount the intercooler in the front of the vehicle.
  • Connect the piping from the turbocharger to the intercooler.
  • Ensure all connections are secure and leak-free.

Step 6: ECU Tuning

After all components are installed, tuning the ECU is crucial for optimizing engine performance. Proper tuning will ensure that the engine runs smoothly and efficiently.

  • Connect the ECU tuning software to your vehicle.
  • Adjust fuel maps and ignition timing for the RB20DET setup.
  • Test the vehicle to ensure proper performance and make necessary adjustments.

Final Checks and Testing

Before hitting the road, perform a series of final checks to ensure everything is functioning correctly. This step is essential for safety and reliability.

  • Check all fluid levels (oil, coolant, fuel).
  • Inspect all connections for leaks.
  • Start the engine and listen for any unusual noises.
  • Take the vehicle for a test drive to assess performance.

Conclusion

Completing an RB20DET turbo swap can be a rewarding experience for car enthusiasts. With careful planning and execution, it is possible to achieve this upgrade for under $1,500. Enjoy the enhanced performance and the satisfaction of a job well done!
