Gen 2 Coyote engine swap into 2017 Mustang Ecoboost?

[Jep thomas]

I have a 2017 mustang ecoboost what all would I need to swap a gen 2 coyote into the car? And would I need to swap the transmission since it’s also an MT82?

It would be better off to sell your Ecoboost and buy the Gt of your choice moneywise in the longrun . Resale value alone wont be dinged. Theres also different wheels , tires and suspension components that are different . Not sure about the gearing in the trans though.

The only reason I choose to swap over trading is because this is my first sports car and I’ve had so many memories with this car and I would like to keep it so I figured I would swap the engine I’m not worried about money just would like to know all the parts I would need to change over than engine, wiring harness, control pack, etc etc

enough parts you should probably buy a complete GT and just swap the vins lol.

Hattrick, gave you the right answer. I understand the sentimentality of the car. However, it could even become an issue smogging the car down the road. I know Georgia isn't one of those states that is so picky when it comes to smogging but it can become one as a lot of states are and you will have real issues.

Also, it just isn't worth it. With the pricing of used cars the way they are sell the ecoboost and go buy a GT.

Jep believe me i know how u feel, i have a C7 that i bought new . Love the car . At the time i was commuting so i ordered it with the auto trans. Now im not and would like to have a manual trans in it for the twisties and the track . Asked the pros about it and gave me the same answer and that was only a trans swap lol

I can't find the thread but a member did a eco to coyote swap. I think it took 9 months most of it trying to get it to run. Seems you need everything from the donor car or you will run into trouble.

Hopefully someone has better search skills than me and can link the thread.

I would mod the hell out of an eb before I ever tried swapping motors. There’s a couple videos floating around youtube of eb making stock gt horsepower.

I’m in the middle of it (except my coyote is a gen3). Number of parts you need will depend on how much stuff you expect to work afterwards, and how comparable the options of the GT donor car and your Ecoboost are. It’s a lot of work. If mine weren’t already a track car I’d have sold it and bought a GT.

Trans does not change over as the bellhousing are different. Front cradle needs to be swapped as well. All electronics and modules. If you don’t swap some you will need to get them reprogrammed and even then depending on what module it is it may not start or work.

EVERYTHING on these cars is on the canbus network, down to the taillights. So if something doesn’t work when you’re done it could be the wiring or the canbus network. Very complicated to troubleshoot.

The MT82 has different gearing in the GT version vs the EB version. I'm not sure what else might be different, but I'm guessing the bell housing and input shaft at least.

It's a moot issue though, as others have said, it's just not worth it to try the swap. The cheapest way to do it would be to buy a wrecked GT, then doing all the labor yourself, strip both cars down practically to a bare shell and take everything from the donor car that's different to put in your EB. If you have to pay someone to do it the cost will exceed just buying a GT to have as a 2nd car.

The issue isn't swapping the mechanical parts, it's that everything is connected electrically, and all the systems have to recognize the basic vehicle data programmed into each of them. If even 1 seemingly insignificant module is left out, it could cause a no start issue that would be nearly impossible (and certainly impractical) to try to diagnose.

You could physically swap in a V8, you'd have to change out the trans, driveshaft, AC lines, exhaust and probably a few other things I'm not thinking of just to get it hooked up, then run a custom fuel system and use the FR controls pack to get it running, but then your instrument cluster wouldn't work, neither would cruise control, and probably a dozen other features as well that most people don't think about and take for granted until they stop working.

I'll just leave this here...

I had a 97 mustang v6, did the engine swap to the v8. Owned that car for 10 years (bought it at 18, engine swapped at 19) and the swap brought with it a mountain of headaches. But I loved that car and 10 years as a daily driver brought with it a lot of memories. I just grew so tired of constantly fixing it... I bought my 2019 GT pp1 on a whim and literally cried sitting in the drivers seat of my old mustang, knowing full well I had to let it go. 3 years later and I have zero regrets. If anything I feel relieved at the amount of free time I have to drive the car instead of tinkering with it. It also often crosses my mind how much better of I would have been ditching the v6 and buying a used GT.


What I'm trying to say is that I've been down that road and absolutely understand how you feel. But at the end of the day it's an inanimate object. You will get over parting with it and you will become attached to the new one. As has been pointed out, it's not easy. I spent a full year just getting all the parts I needed (getting an engine was the easy part). Even with a used wiring harness I spent months chasing electrical gremlins. Once things were finally running, a week never went by without another issue popping up. All this on a platform that is way easier to do a swap on than the s550.


It does bring back fun memories, though. My car friends all like to say that I made it run off of sheer willpower.

Nostalgia and sentimentality are not necessarily bad things but can lead you to make poor decisions and spend inordinate amounts of money unnecessarily.
The engine swap you are considering is likely one such poor decision.
If, as you say,money is not a worry then might I suggest that you keep the Ecoboost, prepare it properly and put it in storage. Then buy the V8 car you want. That course of action will give you the more powerful car you want with less expense in the long run and far more reliability.
You can then decide what to do with the Ecoboost. Either sell it with its value preserved or keep it for 20 or so years and pass it to your children.

A quick story.
For my 40th birthday my wife bought me a new convertible. I drove it for a few years, eventually only very occasionally. A few years in my son asked to drive it to his prom and I let him. About three years ago I gave him the car. Now the car is almost 27 years old and he has a car he can work on with his young daughter that we all have wonderful memories of.

I hope this gives you food for thought and shows there are other options.

Just mod it for more horsepower
