I'm looking to upgrade the engine on my 2014 Fusion SE (currently have the 1.5L stock) and have been trying to find a suitable replacement with far better performance. As I've looked around, the 3.0L Twin Turbo Ecoboost engines in the Lincoln MKZs look like a very appealing option, especially considering the price compared to other options. Would one of these fit in my car? If so, would it massively decrease my gas mileage or would it still be manageable? If not, what are some alternatives? I'd preferably like a quieter option that still has great performance, as I'm looking to mod my car into the perfect sleeper build and I feel the volume of an engine like the 5.0 Mustang engine that went viral a while ago would ruin the subtlety I'm striving to achieve. I'm just beginning to get into car modification, so if there's a smaller change I need or should do first that'd also be great to know.
