We Like This Fox Body Engine Swap Way More Than We Should

EcoBoost-swapped Fox Body Mustang

It has more power than the 5.0 it came with. Oh, and half the cylinders.

Taking the old 5.0-liter V8 out of a Mustang and stuffing something else under the hood isn’t exactly an uncommon practice these days. Many Coyote motors and even a number of Chevy LS motors have found a new home within a Fox Body Mustang. But this swap is quite interesting. Found on Reddit‘s “Just Rolled Into The Shop,” this is an extremely clean orange Fox, with a modern 2.3-liter EcoBoost 4-cylinder.

Obviously, a few eyebrows would be raised by a swap like this, since the 2.3-liter doesn’t exactly have the same level of aftermarket support that the more popular V8 engines enjoy.

Ford does offer the EcoBoost as a ready-to-go crate engine with 310 horsepower and 320 pound-feet of torque. But those are stock performance numbers; we know that this Mustang’s output is likely higher because of that giant turbo.

So, why swap in a 2.3 EcoBoost? An advantage over the 302, of course, would not only be weight but how the engine sits in the car. Mounting the engine farther back in the bay would even out the weight distribution over the front and rear axles, to the point that this Mustang is probably a fun and sprightly car to drive.

Downsides? Well, subsequent discussions on Reddit cast doubt on the 2.3’s ability to make reliable power. Still, we’ve seen plenty of EcoBoosts putting up serious numbers and running just fine.
