Best Ford Fiesta Engine for Performance Upgrades?

I'm interested in upgrading the engine on my Ford Fiesta for better performance. What are some recommended engine options for this car? Is there a specific engine that has more potential for upgrades or aftermarket parts?

As a long time Ford Fiesta owner and enthusiast, I can tell you from experience that the 1.6L EcoBoost engine is a great starting point for performance upgrades. With its turbocharged design, it has a lot of untapped potential for increased power.

I've found success with the 1.0L EcoBoost engine in my Ford Fiesta. It may be small, but it packs a punch and has a lot of room for performance improvements. Don't underestimate the potential of this little engine.

If you're serious about getting the most out of your engine upgrades, I highly recommend the 1.6L Turbocharged engine from the ST model. It's already built for performance and can handle even more power with the right modifications.
