Swapping a 3.5L Ecoboost into.....

I have been collecting a lot of information on the 3.5L Ecoboost engine, in particular the F150's 3.5L Ecoboost engine and 6R80 automatic transmission.

I would be willing to share what I have learned, if anyone is interested.  Here are a couple of thought starters to consider.

1.  The engine is 28-1/2" wide across the turbos, the widest point, and 22" wide across the cylinder heads.
2.  The F150's 3.5L Ecoboost uses a rear-sump oil pan, the exact same pan as used on the 2011-2014 Mustang 3.7L V6 (which also uses the 6R80 auto trans).
3.  The motor mounting bosses on the F150 3.5L Ecoboost block are identical to those on a RWD 3.7L V6 block.
4.  The 2011-2014 Mustang's MT-82 6-speed manual as used behind the 3.7L V6 will bolt right up to the F150's 3.5L Ecoboost engine.  Later this year, Ford Racing will offer a "Controls Pak" for the F150 3.5L Ecoboost engine using a manual transmission.

Anyone have any thoughts?  Want more info?

A Mustang with a 3.5 Eco and an MTX would be quite a road course car.  You could tune it to have at least as much HP as a stock 5.0 and have a lighter front end.

DJE624,
True, and since it fits into a 2011-2014 Mustang, it would fit into a 2005-2010 Mustang as well, and with a tubular K-member it would fit into a 1979-2004 mustang as well.  And it will likely also fit into a 1998-2011 Ford Ranger......

It's a fantastic motor whatever you put it in.  Very high power to weight ratio.

walt460

Yes it is an amazing engine.  It has 6-bolt main bearings, oil cooling jets for the pistons, a forged crankshaft, forged (powdered metal) rods and makes 365HP and 420 ft-lbs of torque and 90% of peak torque from 1700rpm through 5500rpm, on 87 octane fuel. 

A stock 5500# F150 Ecoboost 2WD with a 3.73:1 axle will run the 1/4 mile in 15 seconds or less.  Put that powertrain into a 3500# Mustang and it could run in the 11s and get 30mpg highway FE.

wow you could make a ranger a absolute bullet lol sounds like a dream project.

Just find yourself a totaled F-150 with an Eco and a Mustang with a blown motor and you're all set! 

Edit-Or Ranger.

As of November, 2013, Ford had built 400,000 F150s with the Ecoboost 3.5L engine.  There are plenty of "totaled" 2011-2014 F150 Ecoboost trucks in wrecking yards. 

You can buy a complete powertrain drop-out kit for about $5500, which includes the engine with all accessories & turbos, the transmission, the H-pipe with cats and UHEGOs, the PCM and all the wiring, the steering column with key, the BCM (Body Control Module, which is a smart fuse box), the vacuum pump, the fuel pump and sender with the FPDM (Fuel pump driver module)

To swap this powertrain into a Mustang or Ranger, you need some other parts like a custom air-to-air intercooler, an oil cooler, a larger radiator, modified drive shaft, etc. so I would plan about $8000 budget to be safe.  Still a bargain for the performance that will result.

I wish I had the skill to make something like that happen.

When I had one of my Contour SVT's a while back, I had considered an Ecoboost swap. But given that 3.5EB engines are still rather pricey, it wasn't too serious of a thought for me.

They came with the 2.5 DOHC, and the 3.0 DOHC is an easy direct swap. I figured there had to be some similarities between the 3.0 and 3.5 (Nautilus actually sells a 3.5 for them), in terms of block similarities, dimensions, etc. If it would work, I knew I'd need basically an SHO for parts, to scavenge the wiring harness and all supporting hardware.

If that wouldn't have worked, I wondered about just using the SHO exhaust manifolds and turbos, and bolting them onto the 2.5/3.0 heads. All the would require, I think, would be the same exhaust port bolt patterns, and enough room for them turbos.

Great project.  I'll be interested to see how it comes out. 
My son and I were talking about this for his 69 F150, but never got to it with Christmas schedules.

I think the F150 3.5L Ecoboost with the 6R80 auto trans would make a great upgrade to a 1969 F150!

Talk about Nuevo/Retro!  Sounds pretty cool.
