With Ford offering the Ecoboost crate engines with independent controllers, why don't we see any swaps? To me, it seems like the 3.5l Ecoboost would be a great option for someone's 5.4l or V10 equipped Super Duty or Excursion with a tired or bad engine. I realize that the transmission may not readily bolt up, but that's what ingenuity is all about.
Have you seen or read about a conversion? Was it a build thread somewhere? If so post up a link or tell us your thoughts on the subject.

 

There is no ecoboost in a Super Duty.

 

That is the point of the original post.

 

I guess everyone is waiting to see the BRAVE.. Rich.


3.5L pulling 12.000 pounds for 200,000 miles... without blowing up.

 

Would certainly be interesting to see. Would take a lot of fab work, and the instrument cluster probably wouldn't work. Don't think the existing transmissions would bolt up either, so you'd need to source one of those as well as an engine. Looks like about as much work as the guy who put a 7.3L IDI into his '09 truck.

Do you really think the average Super Duty spends its first 200,000 miles pulling 12K every mile?

 

Who's Rich? Or do you mean BRAVE and wealthy?

As far as the 3.5l Ecoboost pulling 12,000 pounds for 200,000 miles, how does the 5.4l or the V10 do it? Isn't the current F150 with the Max tow package rated for 12,000 lbs or close to it? Doesn't the Gen 2 Ecoboost have 470 lb/ft of torque? Even the 1st Gen had more torque and horsepower at a lower RPM than the 5.4 liter.

Taking maximum towing out of the equation, it seems there are lots of Super Duty / Excursion owners who don't come any where close to using their vehicles at upper end of it's capabilities. I would think that the Ecoboost would provide sufficient motivation and economy for the daily driver / family vehicle owner who might be looking at needing a complete overhaul or replacement of their engine.

 

Thanks for posting the link Tom.

I guess I was thinking of a 1999-2007 truck or Excursion with higher miles needing a swap. Seeing Andrew (The Big Bee) buying my '00 7.3l cab & chassis and swapping the powertrain into his crew cab 5.4 liter truck isn't for the faint of heart. In fact, he still doesn't have everything sorted out completely yet. Of course the new house and new baby will slow down anyone's ability to work on the toys.
Ford makes a stand alone powertrain controller for each of the Ecoboost crate engines. I would think this would help solve some of the complexity involved, but that's the prime reason for this thread. Who's done it and where's the do it yourself information?
While I admit that I probably wouldn't be able to pull off a swap myself, knowledge is power and I find the concept very interesting.

I was previously thinking about finding a nice condition Ranger for short trips and better fuel mileage. The more I read, the more I thought about how cool it would be to swap in a 2.3 liter Ecoboost. I checked a few forums out and found limited posts about guys turbocharging their existing 4/6 cylinder, but no real do it yourself threads with a clearly laid out process. Just lots of posts about so and so did it.

 

NO, I do not... but I have rebuilt turbocharged car engines... that never pulled anything...

but I have NOT seen the inside of a 3.5L.... if its NOT built like a diesel.. it will not live towing heavy..

but then there are reasons Cowboy Cadillac's are made.,

I do know a few F 250's the have a trailer and a Cat-Skid loaded every day..

 

the big thing in my eyes would not be just the fabrication to make it work with the transmission and frame, electronics. But also the cooling system.


What I have witnessed is the motor is certainly capable but cannot keep cool for the long term. that would have to be addresses or the thing would have a meltdown.

 

I think the answer is simple. Why play around with 4-600 ft lbs of torque in a 7klbs truck, when you could play around with well over a 1000ft lbs with a diesel? And do it reliably and get good fuel mileage. I see the appeal in a restomod of an older vehicle. I just think it's silly in a super duty. A diesel conversion in a gas rig would be much easier than a ecoboost conversion. I say all this, but if there had been a FACTORY 3.5 ecoboost option in a superduty, I probably would have bought it. I came close to buying a 2.7eco boost f150 when I bought my 6.2. The 2.7 is a superior motor in the f150 in my opinion.

 

You guys are thinking backwards! Swap the rear suspension of a 350 into an eco boost equipped 150 and see what it will take to destroy it!!

 

While it may seem simple, the idea and work required to convert from gas to diesel is far more complicated. For one, there isn't a stand alone controller designed for any diesel(You will need to swap out complete wire harnesses designed for the diesel). Suspension is set up slightly different(how much more does the diesel engine weigh?). Fuel delivery is far different. We're not even talking about electrical demands yet!
Please explain why you feel the Ecoboost route would be more difficult. Thanks!

 

Haha!

You could be onto something...swap the chassis components and go!

Back on topic: What would the guy who's truck has given up the ghost as far as an engine do?

 

I never said it would be easy. Just easier. Nothing to engineer. If you bought a wrecked diesel, every part is engineered to fit the chassis. Regardless, it's easier to just buy the diesel.

 

Replace it with what's suppose to be in it. You asked
