Na Miata Forced Induction: Comparing Turbochargers from Garrett and Borgwarner for 200+ Hp Gains

by

The NA Miata is a beloved platform for car enthusiasts, known for its lightweight design and engaging driving experience. However, many owners seek to enhance their performance significantly, often aiming for the coveted 200+ horsepower mark. One of the most effective ways to achieve this is through forced induction, specifically turbocharging. In this article, we will compare two popular turbocharger brands, Garrett and BorgWarner, to help NA Miata owners make an informed decision.

Understanding Forced Induction

Forced induction involves compressing the air entering the engine to increase its density, allowing for more fuel to be burned and thus producing more power. Turbochargers are a type of forced induction system that uses exhaust gases to spin a turbine, which in turn compresses the intake air.

Why Turbocharge Your NA Miata?

Turbocharging your NA Miata can lead to several benefits, including:

  • Significant power gains, often exceeding 200 horsepower.
  • Improved throttle response and acceleration.
  • Enhanced driving experience, especially on track days.
  • Potential for better fuel efficiency at cruising speeds.

Garrett Turbochargers

Garrett is a well-known name in the turbocharger industry, offering a wide range of products suitable for various applications. Their turbochargers are renowned for their reliability and performance.

  • Garrett GT2860RS: Known for its quick spool and high efficiency, this turbo is a favorite among Miata enthusiasts.
  • Garrett GTX2867R: Offers a larger compressor wheel for increased airflow, ideal for those seeking higher power levels.

Pros of Garrett Turbochargers

  • High build quality and durability.
  • Excellent customer support and resources.
  • Wide range of options for various performance goals.

Cons of Garrett Turbochargers

  • Can be more expensive than other brands.
  • Some models may require extensive modifications to fit.

BorgWarner Turbochargers

BorgWarner is another prominent manufacturer of turbochargers, known for their innovative designs and performance-oriented products. They offer a variety of turbochargers that cater to different needs.

  • BorgWarner EFR 6258: This turbo is compact yet powerful, making it a great choice for the NA Miata.
  • BorgWarner S200: Offers excellent boost characteristics and is suitable for high-horsepower builds.

Pros of BorgWarner Turbochargers

  • Innovative technology for improved performance.
  • Lightweight and compact designs.
  • Good balance of price and performance.

Cons of BorgWarner Turbochargers

  • Limited availability for some models.
  • May require custom fabrication for installation.

Comparing Garrett and BorgWarner Turbochargers

When choosing between Garrett and BorgWarner turbochargers for your NA Miata, consider the following factors:

  • Performance: Both brands offer excellent performance, but specific models may shine in different areas.
  • Fitment: Ensure that the chosen turbocharger fits well within the Miata’s engine bay and supports your power goals.
  • Budget: Consider your budget and the potential costs of installation and supporting modifications.

Supporting Modifications for Turbocharging

To safely achieve 200+ horsepower with a turbocharger, several supporting modifications are recommended:

  • Upgraded Fuel System: A higher-flow fuel pump and larger injectors are necessary to provide adequate fuel for increased power.
  • Aftermarket Engine Management: A standalone or piggyback ECU can help tune the engine for optimal performance.
  • Exhaust System: A high-performance exhaust will help reduce back pressure and improve turbo efficiency.
  • Intercooler: An upgraded intercooler will help keep intake temperatures down, improving performance and reliability.

Conclusion

Turbocharging your NA Miata can transform it into a thrilling machine capable of delivering 200+ horsepower. Both Garrett and BorgWarner offer excellent options, each with their unique advantages. By considering your performance goals, budget, and necessary supporting modifications, you can make an informed decision that will elevate your Miata experience to new heights.
