The Subaru BRZ is a popular choice among car enthusiasts looking for a balance of performance and handling. One of the most effective ways to enhance the power output of the BRZ is by upgrading to a 68mm turbocharger. In this article, we will explore the best turbo upgrades from Garrett and BorgWarner that can help you achieve over 300 rear-wheel horsepower (RWHP).
Understanding Turbocharging and Its Benefits
Turbocharging is a method of forced induction that increases the engine’s efficiency and power output. By compressing the intake air, a turbocharger allows more air and fuel to enter the engine, resulting in increased horsepower and torque. For BRZ owners, upgrading to a 68mm turbo can significantly enhance performance.
Why Choose a 68mm Turbo?
A 68mm turbocharger strikes an excellent balance between spool time and peak power, making it ideal for street and track applications. Here are some reasons to consider this upgrade:
- Increased Power: Achieve 300+ RWHP with the right tuning.
