Diy Turbo Install on Mitsubishi 3000gt: Step-by-step for $2,500

by

The Mitsubishi 3000GT is a beloved sports car known for its performance and sleek design. One of the most exciting modifications you can make to enhance its power is installing a turbocharger. In this guide, we will walk you through a DIY turbo install for the Mitsubishi 3000GT, with a budget of $2,500.

Understanding the Basics of Turbocharging

Turbocharging is a method of forced induction that increases the engine’s efficiency and power output by forcing more air into the combustion chamber. This process allows for more fuel to be burned, resulting in greater horsepower.

Tools and Materials Needed

  • Turbocharger kit compatible with Mitsubishi 3000GT
  • Basic hand tools (wrenches, sockets, screwdrivers)
  • Torque wrench
  • Oil and coolant
  • Vacuum gauge
  • Boost controller
  • Intercooler (if not included in the kit)
  • Fuel pump upgrade (optional)

Step-by-Step Installation Process

Step 1: Preparation

Before starting the installation, ensure that your workspace is clean and organized. Gather all tools and materials, and read through the turbo kit instructions thoroughly. It’s also a good idea to disconnect the battery for safety.

Step 2: Remove the Stock Components

Begin by removing the stock exhaust manifold and turbo piping. This will typically involve:

  • Removing the intake system.
  • Disconnecting the exhaust downpipe.
  • Unbolting the manifold from the engine block.

Step 3: Install the Turbocharger

Once the stock components are removed, it’s time to install the turbocharger. Follow these steps:

  • Position the turbocharger on the exhaust manifold.
  • Secure it using the provided bolts and torque them to specification.
  • Connect the oil feed line to the turbo.
  • Attach the oil return line to the oil pan.

Step 4: Install the Intercooler

If your turbo kit includes an intercooler, now is the time to install it. The intercooler helps cool the air entering the engine, increasing efficiency. Steps include:

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

Step 5: Install the Boost Controller

The boost controller regulates the amount of boost pressure produced by the turbo. Follow the manufacturer’s instructions for installation, which typically involves:

  • Connecting the boost controller to the vacuum line.
  • Mounting the controller in a convenient location.

Step 6: Reconnect Everything

Now that the turbocharger and intercooler are installed, reconnect the intake system and any other components you removed during the initial steps. Double-check all connections for tightness.

Step 7: Fill Fluids and Check for Leaks

Before starting the engine, fill the oil and coolant to the appropriate levels. Start the engine and let it idle, checking for any leaks in the oil or coolant systems.

Step 8: Test Drive and Tune

After ensuring there are no leaks, take the car for a test drive. Monitor the boost levels and make adjustments as necessary using the boost controller. It’s recommended to have a professional tune the vehicle for optimal performance.

Budget Breakdown

Here’s a rough estimate of the costs involved in a DIY turbo install:

  • Turbocharger kit: $1,500
  • Intercooler: $300
  • Boost controller: $200
  • Miscellaneous parts (hoses, clamps): $200
  • Upgraded fuel pump (optional): $300

Conclusion

Installing a turbocharger on your Mitsubishi 3000GT can significantly enhance its performance and driving experience. With careful planning and execution, you can complete this project within a budget of $2,500. Always remember to follow safety precautions and consult professionals if needed for tuning and installation support.
