The Honda Civic Type R is a popular choice among car enthusiasts, particularly for those looking to maximize performance. One of the most significant upgrades that can be made to enhance power is the turbocharger. In this article, we will compare two popular turbo upgrade options: the Garrett G25-550 and the BorgWarner EFR 8374. Both turbos offer unique benefits and features, making it crucial to understand their differences for peak power.
Overview of Turbochargers
Turbochargers are essential components in increasing the power output of an engine. They work by forcing more air into the combustion chamber, allowing for more fuel to be burned, which results in increased horsepower and torque. Choosing the right turbocharger can significantly impact your vehicle’s performance, especially in a high-performance car like the Civic Type R.
