What is the best engine to upgrade for a Ford Fiesta?

I'm interested in upgrading the engine on my Ford Fiesta, but I'm not sure which one would be the best fit. I'm looking for improved performance and power, but I also want to make sure it's a reliable choice. What engine would you recommend?

I upgraded my Ford Fiesta's engine to a turbocharged Ecoboost and I've been extremely satisfied with the results. The added power and improved fuel efficiency make it the perfect choice for any Ford car enthusiast.

I would highly recommend the Ford Fiesta ST's 1.6L EcoBoost engine. Its compact size and high performance make it a great option for anyone looking to upgrade their Ford Fiesta.

If you're looking for a budget-friendly option, I would suggest going with a bigger engine from the Ford Focus or Ford Fusion. They can easily be swapped into your Fiesta and provide a significant performance boost.
