Gen 2 Coyote engine swap into 2017 Mustang Ecoboost?

[UpACurb]

If money is not an object than keep it and buy a second Mustang ......I mean the only thing better than a Mustang is 2 Mustangs! : )

Not worth doing that swap. Trade it in and buy a GT. It will save you so many headaches, and be cheaper.

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

No offense, but if you weren't worried about money, you would be driving something else besides an Ecoboost Mustang. Maybe a Porsche, or Nissan GT-R? Everybody has a price point they have to meet. You've heard living within your means. I'm sure we all have. No shame here as we all are at different points in our life and at different financial levels. When it comes down to it, we enter this earth with nothing and we leave this earth with nothing. Be truthful with yourself and what makes sense financially. If you were to swap a Coyote motor in an Ecoboost Mustang, you would have enough money tied up in the whole thing to afford a Corvette. Not to mention a worse car than a factory GT. Yes, you have the Coyote motor, but you are missing vital other parts that help balance that Coyote motor. Think GT brakes, suspension, etc.

Sell the Ecoboost and buy a GT if you want the Coyote motor. Engine swaps almost never look as good as a factory car.

That thread is a great read, but basically confirms what I said about this swap earlier, you have to strip everything down to practically a bare shell, then swap everything over from the GT. The only reason this was even remotely feasible financially is he did 99% of it himself in his own garage, relying on a buddy from a Ford dealer with the appropriate laptop to reprogram the necessary modules, cluster, etc, to get everything working correctly. Most of us don't have "insider" friends that can easily tackle the programming issues for us, or diagnose electrical faults to quickly find a broken wire/connector that's throwing a code. Many of us use our car for daily driving, so we can't afford to have our main transportation out of service for the amount of time it took him to complete that swap.

Yes, there are a lot of naysayers around who say it can't be done, but most of the anti-swap comments here have been about it not being practical financially, which for the majority of us is still true. That thread shows it is physically possible, and even for some people an enjoyable experience, but in spite of his success, his circumstances are not typical and doesn't change the fact that for the rest of us, such a project would not likely be cost effective, or even completed as successfully or trouble free.

Personally, I'm not against engine swaps, I actually love the idea of swapping in something that was never an option from the factory. To me that is the ultimate mod, a way to personalize a car to be different than anything else on the road, which isn't always easy to do when there's millions of the same model on the roads, but none of that makes it practical or affordable. Something like this may become more financially practical down the road when the EB cars have depreciated enough that the price gap between them and a GT is so big that the cost of a V8 swap fits within the price gap. Look at the Fox and SN95 Mustangs, GT's always hold their value better than the base cars, the base models are so cheap now that they're a good cheap platform to start with for whatever mods make you happy, but even with that being the case you have to go into it understanding that every dollar you spend is a dollar you won't get back if/when you sell the car.

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.

Not in this case, But people do swaps for insurance reasons also. Pay an eco boost policy but drive a “GT”.

FWIW, my 16 EB and my 20 GT insurance was only different by $20
But, that is NYC insurance. $1700 per year.

Look on Copart for a rear impact or rollover 2017 GT that didn't take a front impact. Another 2017 makes emissions less of a concern and a rollover or rear impact will have more of the needed GT parts undamaged.

You can swap in the Coyote and use a Ford racing control pack to run the engine. So you won’t have to do much to the electrical/computer systems. Just the kmember, transmission, drive train, cooling system, ect, it will still be a lot of work but much easier than swapping everything from another car

If you try to use a Ford Performance control pack you better be planning on it being a stripped out race car because none of the other factory electronic systems will work. Those control packs are designed with only the required components to run the engine in an older car, like a restomod swap.

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.

That was redmus. He's also on insta. And yeah, it woulda been cheaper to just got a GT.

Thanks wildhorse.

Here is a link to the thread.

You let the control pack run the engine and the cars computers run the car. Keep it two separate systems. I’m not saying that it will be a plug and play setup. It will still be a PITA but it would be easier

It wouldn't work that way, the cars modules need input from the engine computer, if the controls pack is running the engine, the PCM won't have any data from the sensors and throw a ton of codes, it may even get stuck in some standby mode thinking the engine isn't even running since it doesn't have any input.

Yeah it won’t work that way. For example without the stock PCM neither the gauge cluster nor the steering rack will operate. Steering rack won’t even power up. If you don’t use the stock PCM you’re pretty much relegated to rewiring the whole car.
