2.3 Ecoboost into Fiesta?

Hello, I am not mechanically inclined by far but I was wondering about the possibility of and all the parts youd need to replace for a engine swap of a 2.3 Ecoboost out of the 15-17 Mustangs into a 2016 FiST? Any additional comments and other engine swap options are highly welcome. Thank you.

Thank you, I definitely forgot to look up this idea before posting.

Ford already did it for a SEMA project. Having done engine swaps in the past, I would not do one again. I consider myself fairly mechanically inclined. The amount of work, reliability, cost, more cost, even more cost, time spent fixing things that didn't work, more cost again, and the massive amount of time involved would not be something I would want to do again. I have seen so many friends take a really nice car and try an motor swap. After years of work, they get rid of the car with the swap never completed. The car is sold for pretty much nothing since it doesn't run and is full of mismatched parts. They never come close to recovering the money spent. Instead of enjoying a really nice car, they turned it into a money eating, dust collecting, garage decoration.

Certain platforms really take well to an engine swap (Miata, s2000, VW bug, VW bus, drag cars). The FiST platform, however, is not one of them. It has a certain balance that would be greatly disturbed with a bigger, heavier, higher center of gravity motor.

Spend the money on a complete motor build, cams, turbo, extra fuel. It will turn out better and be cheaper too.

If I may, what have done to increase power output on the 1.6 you have now?

Just the accessport really, I have an exhaust and downpipe but have yet to be able to out them on and saving up for everything else. My thinking though was I wanted to get input on the engine swap idea before buying anything specifically for this motor because what's the point of getting all these bolt on and other engine upgrades when I was just going to engine swap it. But after hearing some views and looking at that other post linked above, I think I'll just stick with this motor so I'm gonna start looking at more upgrades for it.

"I have no idea what I'm doing, but can anyone give me a parts breakdown of this insanely custom, one-off project that only a highly skilled mechanic would even dream of doing over the span of a few years? This will be my daily driver."

I really love threads like this.

Many moons ago, I spent some time with the Focus hatchback with a 2.5L SVT Contour motor shoved in it. The car was built by SVT using a car brought over from Europe. It went pretty fast in a straight line, but had horrible torque steer and the handling wasn't nearly as good thanks to all the weight from the larger motor. No idea what that thing cost to build, but it is safe to say that it is far more than most Fiesta ST owners have to play with. Plus, it was built by a team of highly skilled engineers and fabricators. The point is that even with a massive, if not close to unlimited budget, a team of highly skilled individuals, sometimes the end result wasn't as good as you were expecting. The SVT Focus, which came out years later, had similar power and was far more balanced. An engine swap isn't always the right answer. A properly built and tuned engine might be the right thing to balance the car. Yes, I know that runs counter to just about every bro on Facebook who posts on car pages.

Okay then, I highly suggest getting a bigger intercooler, and an E30 tune. It’ll feel like you did an engine swap in comparison to your Cobb OTS, downpipe, and exhaust you have now. Hell, if it were me, I’d sell that downpipe, and exhaust- then use that money for an intercooler, and an E30 tune :)

You cannot fit a 2.0 or a 2.3 liter ecoboost into the Fiesta, period. I remember watching an interview where they were talking about one of Ken Block's Fiestas. When they asked what was the hardest part of the build, they said it was fitting the 2.0 into the Fiesta engine bay. It does not fit. Even with the engine bay stripped of everything, it did not fit.

They had to do a lot of hacking, cutting, etc. They chopped up parts of the frame/unibody/subframe or whatever...it has been too long...in order to shoehorn the engine into the car. They said it has the absolute hardest thing they had to do, a real pain in the ass...and that is with Ken Block money.

There was a gentleman in the UK that shoehorned a 2.0 from the FoST into a normal Fiesta long ago before the FiST was released. I wish I could find that damn thread on ye Olde Fiesta Faction. It was a featured ride in the Fast Ford magazine... Soooo, yes it’ll fit.

Edit: linky to his build

Also, as BRGT’s post says, it would be a compromised ride. For less money than the swap would take, your results on doing a turbo swap on the 1.6 would give comparable output with far less agony.

Except, as I mentioned before, Ford Performance built a 2.3L powered Fiesta for SEMA. I am curious where you found that bit about Block's Fiesta. The reason is that the cars were all built by MSport, except for the very first stage rally car that was built from an OlsbergMSE rallycross car. His Gymkhana, stage rally, and rallycross Fiestas are pretty far removed from a factory car. None were built by Block. The GRC and FIA World RallyCross cars may have had longitude mounted engines, much like the Olsberg cars. I never was able to get a good look at what was under the hood on the MSport GRC cars. They kept them pretty well covered. The Olsberg cars have nothing production past the firewall. It is all a tubular structure. I have seen under the hood of the stage rally cars, but don't have many pictures. There isn't anything remotely production looking under there. Most of the structure is fabricated to allow for the different suspension pick-up points, driveline placement, and tie-in to the roll cage. His cars have used a mix of either 2.0L or 1.6L engines, but none are close to a production engine. They share displacement and the number of pistons. His suggestion that the 2.0L doesn't fit when his cars do run a 2.0L engine seems a little off. That and the cars aren't built by Block's team, they are all built by MSport as customer cars.

Did a Evo3 engine swap into my 2g GSX
Way back in the day. Lots of work and headaches.

Early to mid 20’s me would do it in a heart beat.

40 yr old me is having a hard time motivating myself for the MRX install.

My advice is to spend the money elsewhere

I wished I could put a transmission with taller gears in mine, but the chances of this working out are near to zero of that happening.
When I look at the 1.6 T engine bay, it's cramped in there.
I doubt any larger engine would fit, unless you plan on compromising the crumple zone of your car, by cutting away parts of the frame.
I mean, it's been done before...
What would make more sense, is installing a twin turbo, have a tune done, and run on ethanol.
It'd be about a $3k project, and a lot cheaper than an engine swap like mentioned.

Might be better to think of welding the Fiesta's body on the Mustang's chassis.

Haha, yeah no kidding. 20 year old me would have said let's grab some beers and swap engines! Almost 40 year old me puts together a cost to benefit matrix, logs hours of reading and researching, sits up at night contemplating all the things that could go wrong and the affect on long term reliability, develops a decision matrix based on key attributes, considers how much spending could be allowed before the wife starts to question, and this is just on deciding what brake pads and rotors I should go with.
