What is the best engine for a Ford Focus ST?

I am considering buying a Ford Focus ST and I want to know which engine would be the most reliable and perform the best. Currently, I am torn between the 2.3L EcoBoost and the 2.0L EcoBoost engines. Which one do you recommend and why?

I would highly recommend going with the 2.3L EcoBoost engine. It is a powerful and reliable engine that will give you the performance you desire from the Ford Focus ST.

In my personal experience, the 2.0L EcoBoost engine is the better choice for a Ford Focus ST. It is a more refined and efficient engine compared to the 2.3L.

Based on my research and discussions with other Ford Focus ST owners, the 2.3L EcoBoost engine is the way to go. It offers a perfect balance of power and reliability.
