I had a bit of a change of heart with my build (hence the new build thread), so now I'm trying to swap a 3.5L Ecoboost V6 from an F150 into my 2012 Mustang! Why? Because I can, and I want to. I don't expect it to be cost effective. I don't care about resale value. I'm not trying to build an all out race car. Needless to say, please don't post how stupid an idea this is or trying to convince me to do something else. I'll be using a Ford Racing Control Pack to simplify getting it running. My swap will likely remain very street oriented. This is (or rather will be) my daily driver, and I'm perfectly happy to make compromises to keep the car extremely streetable and comfortable. I don't care if it's loud or rides a bit harsh, I just want it to drive and feel like a typical bolt on car. This means no roll cage, seat deletes, fancy tires that can't handle hurricane season, NOS, insulation removal, or anything of that nature.
Now for a few FAQs:
How much will it cost? A lot. Truth be told I'm not really sure but I'll let you know when I know. I'm expecting to spend at least 7k. (Edit: Well 7k didn't get me too far... 10-15k is more like it)
How much power will it make? A healthy amount. Again, I can't say for sure, no vehicle with this exact powertrain has ever been up on a dyno. I'm expecting around 450+ whp after tuning when the initial project is done. (Edit: we achieved 435whp with a conservative tune on 93 octane with a 250cc water/meth spray at 8psi for safety) I plan to take it over 500whp at some point in the future, but honestly, anything more than 600 just seems excessive lol.
How fast will it go? Don't know, don't care. I have no interest in running faster than 11.5 in the 1/4 and that is probably an attainable figure with the right tires. Ideally I would like to run high 11s on street tires (but that isn't really the main goal, low 12s will be fine with me).
How hard is the swap? I would say it is around medium difficulty. Stock 3.7 trans and motor mounts will work and stock accessories will bolt up, but that's about it. It needs a new ECU, fuel system, a lot of electrical work, and a lot of custom plumbing. The most difficult part is getting all of the original features you want to retain (AC, EPAS, gauges, etc.) working.
The Car:
Around May of last year I picked up an Ingot Silver 2012 V6 with a manual trans with around 40k miles on the clock. My other car (basically a modified WRX) had turned into a less than reliable, if still pretty fun money pit. The Mustang was supposed to be a mostly stock daily ...yeah right. It didn't take long for the first mods to start and you can probably imagine where it ended up. This was my build thread before I decided on a swap:

The Engine:
I picked up a 2014 3.5L EcoBoost V6 on eBay for a steal. It only has 34k miles on it and came with literally everything, from turbos to accessories. I won't need all of it obviously but it's nice to have and I can sell what I don't need.
What's done so far:
As of right now, the car has everything BMR makes for the rear suspension, a Dynotech 4" aluminum driveshaft, Blowfish shifter support/safety loop, Koni STR.Ts with BMR street springs, and a few other things.
Right now I'm working on getting the 3.7 out and putting the 3.5 in. Unfortunately I have a strong feeling this is going to be the easiest step lol. I have ordered the clutch and flywheel that will be going on the 3.5 and the 3.7 is just about ready to come out. Once everything gets here and I have a free weekend, I'll go ahead and make the switch. I'm also in the process of moving the battery to the trunk and finishing up the suspension. I'll be doing YouTube videos as I go along as well. The first one could be better, but it's not too bad at explaining what's going on with the car right now:
There's still lots to do, but I'm excited to get this swap going!
