The Nissan 350Z is a beloved sports car known for its balance of performance and affordability. One of the most effective ways to boost its power is by installing a turbocharger. In this article, we will explore the process of installing a GT2871R budget turbo on a Nissan 350Z, which can increase horsepower from 287 to an impressive 380 HP.

Understanding the GT2871R Turbocharger

The GT2871R is a popular choice among enthusiasts for its efficiency and power potential. It offers a good balance between spool time and peak power, making it suitable for street and track use. Here are some key specifications:

  • Compressor Size: 71mm
  • Turbine Size: 60mm
  • Maximum Boost: 1.5 bar (22 psi)
  • Ideal for 2.0L to 3.0L engines

Required Tools and Parts

Before starting the installation, gather all necessary tools and parts to ensure a smooth process. Below is a list of what you will need:

  • GT2871R Turbocharger
  • Turbo manifold
  • Wastegate
  • Intercooler
  • Boost pipes
  • Oil feed and return lines
  • Fuel injectors (upgraded)
  • ECU tuning software
  • Basic hand tools (sockets, wrenches, etc.)
  • Torque wrench

Preparation for Installation

Before diving into the installation, ensure your Nissan 350Z is in good working condition. This includes checking the engine, transmission, and overall vehicle health. Here are some preparation steps:

  • Perform a full oil change.
  • Inspect the cooling system.
  • Check the fuel system for leaks.
  • Ensure the battery is fully charged.

Step-by-Step Installation Process

1. Remove the Stock Components

Start by removing the stock intake and exhaust components. This includes:

  • Intake manifold
  • Stock exhaust manifold
  • Stock turbo (if applicable)
  • Downpipe

2. Install the Turbo Manifold

Once the stock components are removed, install the turbo manifold. Follow these steps:

  • Align the manifold with the engine block.
  • Use new gaskets to prevent leaks.
  • Tighten the bolts to the manufacturer’s specifications.

3. Mount the GT2871R Turbocharger

Next, mount the GT2871R turbocharger onto the manifold:

  • Secure the turbo using the provided bolts.
  • Connect the oil feed and return lines.
  • Ensure all connections are tight and leak-free.

4. Install the Intercooler and Boost Pipes

The intercooler is essential for reducing intake temperatures. Here’s how to install it:

  • Mount the intercooler in front of the radiator.
  • Connect the boost pipes from the turbo to the intercooler and from the intercooler to the intake manifold.
  • Ensure all clamps are secured properly.

5. Upgrade the Fuel System

To support the increased power, upgrading the fuel injectors is necessary:

  • Remove the old fuel injectors from the fuel rail.
  • Install the new, larger injectors.
  • Reconnect the fuel rail and ensure all connections are tight.

6. ECU Tuning

After installing the turbo and supporting components, it’s crucial to tune the ECU for optimal performance:

  • Use tuning software to adjust fuel maps and boost levels.
  • Monitor engine parameters to ensure safe operation.
  • Consider a dyno session for precise tuning.

Testing and Final Adjustments

Once the installation is complete, it’s time to test the vehicle:

  • Start the engine and check for leaks.
  • Monitor oil pressure and temperatures.
  • Take the car for a test drive and assess performance.

Conclusion

Installing a GT2871R turbo on a Nissan 350Z can significantly enhance its performance, raising horsepower from 287 to 380 HP. With careful preparation, the right tools, and a thorough installation process, you can enjoy the exhilarating power boost that comes with forced induction. Always remember to tune your vehicle properly to ensure reliability and performance.
