When it comes to upgrading the turbo system on your E63, selecting the right turbocharger is crucial for achieving optimal performance. Among the most popular options are the BorgWarner K16 and K27 turbos, both of which are capable of supporting over 700 horsepower. In this article, we will explore the features, benefits, and considerations of each turbo to help you make an informed decision.
Understanding Turbochargers
Turbochargers are essential components in enhancing engine performance. They work by forcing more air into the combustion chamber, allowing for more fuel to be burned and thus increasing power output. The choice of turbocharger can significantly influence the driving experience, responsiveness, and overall performance of your vehicle.
