Cost Breakdown: Upgrading 4b11t to 400 Hp with Garrett Gtx Turbo and Supporting Mods

The 4B11T engine, known for its robust performance, can be significantly enhanced with the right modifications. Upgrading it to 400 horsepower requires careful planning and investment. This article breaks down the costs associated with upgrading the 4B11T engine using a Garrett GTX turbo and other supporting modifications.

Understanding the 4B11T Engine

The 4B11T is a turbocharged inline-4 engine used in various Mitsubishi models. It is known for its potential to handle increased power with proper modifications. Before diving into the upgrade costs, it’s essential to understand the engine’s baseline performance and capabilities.

Key Components for the Upgrade

To achieve 400 horsepower from the 4B11T engine, several key components need to be upgraded. Below is a list of the essential modifications required:

  • Garrett GTX Turbocharger
  • Upgraded Fuel Injectors
  • High-Performance Intercooler
  • Upgraded Fuel Pump
  • ECU Tune
  • Exhaust System Upgrade
  • Stronger Engine Internals (optional)

Cost Breakdown of Each Component

Each component plays a crucial role in the overall performance of the engine. Below is a detailed cost breakdown of each component necessary for the upgrade:

1. Garrett GTX Turbocharger

The Garrett GTX turbocharger is one of the most significant upgrades for achieving 400 horsepower. The cost typically ranges from $1,200 to $2,000, depending on the model and specifications.

2. Upgraded Fuel Injectors

High-performance fuel injectors are essential for delivering the necessary fuel to match the increased air flow from the turbocharger. Expect to spend between $400 and $800 for a set of high-flow injectors.

3. High-Performance Intercooler

An upgraded intercooler helps reduce intake temperatures, improving performance and reliability. Prices for high-performance intercoolers range from $300 to $1,000.

4. Upgraded Fuel Pump

A high-flow fuel pump is necessary to ensure adequate fuel delivery under increased demand. The cost for a suitable fuel pump can range from $150 to $400.

5. ECU Tune

Tuning the engine’s ECU is critical for optimizing performance after modifications. Professional tuning services typically cost between $500 and $1,500.

6. Exhaust System Upgrade

An upgraded exhaust system enhances airflow and reduces back pressure. Expect to pay between $300 and $1,200 for a quality exhaust system.

7. Stronger Engine Internals (Optional)

If you’re planning to push the engine beyond 400 horsepower, consider upgrading the internals. This can cost anywhere from $1,000 to $3,000, depending on the parts used.

Total Estimated Cost

Summing up the costs of each component provides a clearer picture of the total investment required for the upgrade. Here’s a rough estimate:

  • Garrett GTX Turbocharger: $1,200 – $2,000
  • Upgraded Fuel Injectors: $400 – $800
  • High-Performance Intercooler: $300 – $1,000
  • Upgraded Fuel Pump: $150 – $400
  • ECU Tune: $500 – $1,500
  • Exhaust System Upgrade: $300 – $1,200
  • Stronger Engine Internals (Optional): $1,000 – $3,000

The total estimated cost for the basic upgrade to 400 horsepower without optional internals ranges from $2,850 to $7,900. Including stronger internals could raise the total to between $3,850 and $10,900.

Conclusion

Upgrading the 4B11T to 400 horsepower using a Garrett GTX turbocharger and supporting mods is a substantial investment but can yield impressive performance gains. Proper planning and budgeting are essential to ensure a successful upgrade. Always consider consulting with a professional to optimize your setup and achieve the best results.
