The Ford 2.3L four cylinder turbocharged ecoboost engine has been around for a while now. First debuting in the 2015 Ford Mustang, the small & mighty four banger Ford has been a very popular choice for Mustang buyers. Despite it's rough start and lack of initial interest, ecoboost sales began to take off, as the S550 Generation Ford Mustang continued to evolve. Over the past 8 years of production, Ford only made two variants of the 2.3L ecoboost engine. There is the standard run of the mill 2.3L that you will find in the Mustang, Ranger, and Explorer. Then there is the more special and rarer version that first came in the 2016 Ford Focus RS, then later in the 2020 HPP ecoboost Mustang. Since the arrival of the RS 2.3L, many have wondered what exactly makes it better than the standard 2.3L ecoboost. What we do know is that the RS block and cylinder head is casted of a different (stronger) alloy, and it's fitted with different pistons, camshafts, and a larger turbocharger. H
