So I don't know if anybody uses this forum anymore, however I swapped a 3.7 V6 out of a 2014 Mustang into my 2000 New Edge. I wanted to see if that's something that would interest anybody here. I can post pictures and how I did it if anybody is interested or wants help on how to do it themselves.
 
Here's the car in question. A 2000 Tropic Green Mustang. Originally a 3.8 5 speed V6. It briefly had a semi built 4.3 V6. I swapped to that after a freak accident with a puddle caused the original 3.8 to hydrolock so badly that it put the rods through the block. That 4.3 spun a bearing a month after I swapped it. That engine cost me $3000 unfortunately. This was my first car I got right after highschool. After that happened I bought a 2004 Ford Focus ZX3 2.3 5speed (which I still have) to use as my new daily and turned this into a project car.

I decided to swap a 3.7 for weight, MPG, HP, and cost. The 3.7 is superior to the 3.8 in every respect when you compare those attributes. I also like to be different. Nobody has a 3.7 swapped New Edge. In fact I wouldn't be surprised if I'm the only one in the world. I cannot find a single person (at least on the internet) who has done this. At best I've found some incomplete swaps in other cars. My hope was to be under 3000 pounds have over 300 horsepower and get 30 MPG highway. I've achieved at least one of those so far.

I've kept nearly perfect notes on the cost of this particular build if anybody wants that. I also have a list of parts I used as well. I don't know if I'll go through the work to post all of that here but I will gladly give that information if you'd like. The swap is complete but the car isn't finished. It does run and drive just fine. However the fit and finish etc and finishing touches to really make it "nice" aren't there yet. It's a bit rough around the edges.

I'll break this down into sections as best I can. I'll start with the 3.7 engine. Approximately 30k miles, 2014, 3.7 out of a Mustang. I purchased the big parts LONG before COVID hit and as such they were less than half what this stuff would cost today. I got the engine from an LKQ for $750.

Now if you've made it this far you're probably wondering, what did he use to mount that engine? Fret not, I too wondered that for a LONG time while I was planning this swap. The answer is an AJE K member with their 3.5 eco/3.7 mounts. I lucked out that something like that existed because I don't have the equipment to do proper fabrication nor much know-how in that particular area. With their K member and their mounts the engine was a true "bolt-in" affair. I did not move anything, cut anything, or clearance anything. It (barely) clears the stock brake booster, the steering rack, firewall, and the everything else in the engine bay just fine. This engine will NOT clear the stock hood. I ended up using a 2015 Mustang intake manifold (bolt-on part) because it's lower than the 2014 manifold. Even with that the engine still hit the hood (about .5-1 inch too high). If you have newer new edge your hood shape is different and it may clear, I'm not sure. But for my factory hood it did not. This engine is tall. If I dropped the engine down to clear, the oil pan would hang down below the k member and steering rack which I did not want. I opted to make a cutout in the hood to clear that last half inch which I rather enjoy the look of.

I used a flaming river manual rack (15:1 ratio) because I figured power steering is overrated. Also so is the work required to adapt power steering to an engine that never came with a power steering pump (in a mustang) in my opinion. I also like having less engine bay clutter as well as the weight reduction. I used a maximum motorsports steering shaft to connect that steering rack to the steering wheel. I also used their bump steer kit for the business ends. Also all bolt-on, no modifications whatsoever.

How did you incorporate the 3.7 harness to the SN?
And the transmission mount?
hydro clutch?
I bought a coyote swap harness from Power by the Hour and connected that up to a 2014 Mustang V6 PCM with the PATS deleted. I had to slightly modify the coyote swap harness. Basically just had to switch 2 wires on the ECU connector for the MAF sensor. I left nearly all of the original body harness in my car alone. I tapped into the ignition switch wiring for starting the new engine. I also chose to splice into the existing fuel pump wiring that runs to the trunk. I mounted a FPDM from a 2014 into the trunk and connected that to an upgraded 340LPH drop-in upgraded fuel pump from American Muscle. Item# 393283.
For the transmission I bought a new transmission harness from a 2014 mustang and just plugged that in to the ECM and engine harness etc. as well. Basically 99 percent "plug and play" with no serious wiring modifications needed.

Transmission mount is a Stifflers mount designed to be used with MT82/6R80/10R80 in 79-04 Mustangs. Sku: STF-6R80KIT. That bolted in and fit the MT82 just fine. No modifications for the mount needed.

For the clutch I used a hydraulic conversion kit made by Modern Driveline. SKU: MD-910-0092. I also bought an adapter to go from an AN fitting to the factory Ford push lock connection for the OEM style hydraulic throwout bearing. Plugged the two together and I was good to go.

I actually have everything except the Body harness, MT82 and transmission crossmember.

So Thank you for the information.

I have a 17' transit 150 PS pump for my 3.7. just a FYI.

Are you trying to swap it as well?

You don't need a new body harness if you go my route. I meant I left my 2000 mustang body harness alone.

That's cool, I had heard mention of that PS solution but never bothered. Where does it mount onto the engine?

I am,
I have a 98 and just need a transmission, as well as a drive by wire solution

the pump mounts below the A/C compressor, there is always electric PS pumps via Mopar, Toyota or Volvo.

You could use the factory drive by wire pedal. That's what I did. Works fine. There's a bracket that you can get to bolt it in as well.

I'll document more of the swap soon.

If you're able to use a T56, T5 (would have to be beefed up), TKO, OR TKX. Basically anything other than an MT82 you'll have less problems with fitment. MT82 was the only real fitment issue of the entire swap other than the hood I suppose. I had to hammer and cut my tunnel to get it semi straight in there

I will be looking for a MT82, the Quicktime bellhousing to adapt a Tremec plus the Tremec is close to 3200,00

What a great thread! Keep on going please. I have been collecting parts to do a similar swap of a 3.7 and MT82 into a 1989 Chrysler Conquest. So far I have the car, 3.7 engine, factory wire loom and "brain box" plus all the hoses and a stock radiator plus a ton of bits and pieces. I think I scored a low mileage MT82 today. It has 50k miles on it and is being shipped from Florida. Now I am concerned with location of that goofy shifter as it may end up too far back in the car.

Cheers and damn the torpedos! I think this engine has great potential for a compact power package. I can see twin turbos in the future. :cool:

Oops, I forgot to ask if anyone has dimensioned the 3.7 and MT82 both together, and separately? What I really want to know are overall dimensions of the motor; height from bottom of pan to very top of intake, width from valve cover to valve cover, and length from the forward most piece to bellhousing surface. Also length from the bellhousing surface of trans to the shifting stick.

Many thanks,

Randy
