Building a 700 Hp Toyota Supra: High-performance Turbo, Intercooler, and Fuel System Upgrades

by

The Toyota Supra has long been a symbol of performance and tuning potential. For enthusiasts looking to push their Supra to the limits, achieving 700 horsepower is a thrilling goal. This article will guide you through the essential upgrades needed for turbocharging, intercooling, and enhancing the fuel system to achieve that power figure.

Understanding the Basics of Performance Upgrades

Before diving into specific upgrades, it’s crucial to understand the fundamentals of how these components work together to increase horsepower. Each part plays a vital role in the overall performance of your Toyota Supra.

  • Turbocharger: Increases the amount of air entering the engine, allowing for more fuel to be burned.
  • Intercooler: Cools the compressed air from the turbo, increasing its density for better combustion.
  • Fuel System: Ensures the engine receives the right amount of fuel to match the increased air intake.

Turbocharger Upgrades

The turbocharger is the heart of your power upgrade. To achieve 700 horsepower, you need to select a turbo that can handle the increased airflow and boost levels.

Selecting the Right Turbo

When choosing a turbocharger, consider the following:

  • Size: A larger turbo can produce more power but may have a higher lag.
  • Type: Ball bearing turbos offer quicker spool times compared to journal bearing turbos.
  • Brand: Popular options include Garrett, BorgWarner, and Precision Turbo.

Installing the Turbocharger

Installation requires careful attention to detail. Follow these steps:

  • Remove the stock turbo and associated components.
  • Install the new turbo using proper gaskets and hardware.
  • Ensure all connections are secure and leak-free.

Intercooler Upgrades

An upgraded intercooler is essential for maintaining optimal air temperatures and preventing heat soak during high-performance driving.

Choosing the Right Intercooler

Look for an intercooler that offers:

  • Core Size: A larger core provides better cooling but may require modifications.
  • End Tank Design: Efficient end tanks improve airflow and reduce pressure drop.
  • Material: Aluminum is lightweight and offers excellent heat dissipation.

Installing the Intercooler

Follow these steps for installation:

  • Remove the factory intercooler and piping.
  • Install the new intercooler in the designated space.
  • Connect the piping securely, ensuring no leaks.

Fuel System Upgrades

With increased airflow from the turbo and intercooler, your fuel system must be upgraded to supply adequate fuel to the engine.

Upgrading Fuel Injectors

High-performance fuel injectors are critical for delivering the right amount of fuel. Consider these factors:

  • Flow Rate: Choose injectors with a flow rate suitable for 700 HP.
  • Type: Direct injection vs. port injection can affect performance.
  • Brand: Brands like Injector Dynamics and DeatschWerks are reputable choices.

Upgrading the Fuel Pump

A high-flow fuel pump is necessary to keep up with the increased demand. Look for pumps that can handle the horsepower target:

  • Fuel Pump Type: Consider in-tank vs. external pumps based on your setup.
  • Brand: AEM and Walbro are popular choices for high-performance fuel pumps.

Fuel Management System

A proper fuel management system is essential for tuning your vehicle to run optimally:

  • ECU Tuning: Custom tuning is necessary to maximize performance.
  • Wideband O2 Sensor: Helps monitor air-fuel ratios for optimal performance.

Tuning Your Toyota Supra

Once all upgrades are installed, tuning is the final step to ensure your Supra runs smoothly and achieves the desired power output.

Choosing a Tuner

Selecting an experienced tuner is crucial. Look for tuners with a track record in high-performance builds:

  • Experience: Ensure they have experience with Toyota Supras and turbo setups.
  • Tuning Software: Familiarity with popular tuning software like EcuTek or Cobb.

Tuning Process

The tuning process typically involves:

  • Initial baseline runs to assess current performance.
  • Adjustments to fuel maps and ignition timing for optimal performance.
  • Final dyno runs to confirm horsepower and torque figures.

Conclusion

Building a 700 HP Toyota Supra involves careful selection and installation of turbo, intercooler, and fuel system upgrades. With the right components and tuning, you can unlock the full potential of your Supra and enjoy an exhilarating driving experience.
