Do a search and you will think they are both garbage and all have problems. They really dont though. Just get the one you like best. For me it was 5.0. I like the eco just fine. You have two good choice.

If you're buying used, get the one with the least mileage then.

50k on my '13 3.5 V6 turbo. Oil changed every 5k. No engine problems of any kind. I had to have the front and rear brake rotors turned at 50k. The biggest problem so far is that while towing a 6700# camper up the hills in 5th gear, the rpms are so low that I can barely hear the engine running. Good mileage @ 65 mph on the hwy. Hoping for 250k on the engine. Who knows if it it'll last?



This chart is for the '11-'14 engines. The '15 5.0 has a little more HP.
If your particular load condition requires 200 hp, the 3.5 turbo produces it at 2500 rpm. The 5.0 has to get up to 3500 rpm to produce 200 hp.



It's an ad, but they did do the teardown in public.

Not to be a smart Alec, but do you understand what a turbo motor is and how it works? Maybe a little education on the subject can help you make an informed decision.

In a nutshell, a turbo is a power adder. It uses the pressure or power of the exhaust flow to turn a fan if you will, to ram more of the fuel/air mixture into your combustion chamber. This builds more power but also increases cylinder pressure. It's an extremely efficient design as the exhaust flow is unused energy. A power adder like a supercharger requires a belt to drive it. The power loss associated with the belt theoretically robs power because there are accessory pulleys to turn which causes a drag effect on the motor.

That being said, a turbo is more moving parts which require oil lubrication to keep cool and more moving parts that can break down. However, it allows you to get V8 power out of a smaller motor such as a V6 or 4cyl.

My only real experience with turbo motors is with turbo Subaru's. Believe it or not my wife LOVES them. Back in 2004 we were searching for a new car for her. We stopped by. Subaru dealer because she was impressed with their 5 star crash rating. We went in looking for either a Forester or Outback wagon. She ended up buying a low mileage but used 02 WRX wagon with the turbo 2.0 motor. We got it with only 15,000 miles on it and it was an absolute BLAST to drive. My wife put 168,000 miles on that car with not a single issue other than general maintenance. That little WRX would get up and go and she loved it.

She now has an 05 Outback wagon XT (turbo 4 cyl). We scored it last year when a local dealer had it listed as a one owner car with only 52,000 original miles. She loves it and will be a turbo Subaru owner for as long as they make them.

Only 2500 miles on 2015 3.5 no probs thus far, not saying much of course. Mpg 17 evenly mixed driving.

Would hope ford address any commonly reoccurring issues with previous issues of ecoboost and learned for previous design flaws.

They stuck with ecoboost concept, says something and the v8 seems to be taking a back seat to v8. You get two v6 options and one v8, dealer said for moving away from v8 next year...not sure of the validity;-).

But if ford putting their Apple in the v6 basket...thennnnn

Haven't towed anything yet but will this weekend. Normal driving no complaints with v6 other than missing the growl of v8, but would give that up for slightly less trips to gas pump

Ohh...I gotcha?!....wink, wink, nudge. Ahh, yeah me either - Pinocchio.

I think the longevity question will be hard to answer for the new 2015 ecoboost engines.

Not expecting to much the 2.7 would be very good on gas. However i guess a good point often raised is the fact the the turbos are additional items to maintain or malfunction.

My personal logic or opinion was based on the fact that turbos have been used in cars for a while, with advances in technology over that time. Ford choose to stick with the ecoboost and is the standard or base option/ they (ford) seem to believe in it. I would could the fuel flex system another component susceptible to failure.

I have the 3.5 and my turbos or (the meter) harley shows them boosting. Even thought im sure they are always running. They don't kick in unless they are needed ( for me if if im accelerating hard, going up step hill, or certain towing conditions)

I would say if not towing at all and you don't want the power, cross out the 3.5l

I would be interested in responses of the longevity of the new motors which haven't been around very long.

I have a 2014 ecoboost. Bought it with 158 miles on it. I love it. I do miss the V8 sound as well. Buy what you like and what fits your needs. Simple fact is, if you take care of your vehicle then it will last.

I will state the reason why I went with the Coyote 5.0 engine over the ecoboost. First rule and it has always been true is that cubic inch displacement always equals more power. It is true in natural aspirated engines as well as power adder engines. Okay sure the V-6 twin turbo direct engine makes more power than the 5.0, everybody knows that. But look at it this way, offer the same system of power adder on the 5.0 engine and look for at least 33 percent more power. The 5.0 engine has been well proven in very high power situations to hold up for durability and major power. If somebody would offer a turbo kit for the 5.0 f 150 coyote engine it would be the engine of choice. Mustang guys have run 7 second 1/4 mile times and get 25 mpg. That could easily be turned into a stump pulling motor that could out pull most diesels and last longer. Gas engines are really gaining and also remember that the 5.0 is not direct injected yet, but expect to see that soon. Turbo 5.0 is the wave of the future but Ford is afraid of the power that it can produce.

This is gonna be good.

Nope. The 5.4 is less power than than the 5.0

Nope. The 3.5TT is more power than that 5.0

Yep. But you literally argued opposite of this the previous two sentence you wrote.

Nope. A tune on the EB gives significantly more power than a tune on the 5.0

Sure.

There are several Supercharger kits, still not the engine of choice

Sure. This is a discussion about trucks, right?

LOLWUT?

Of all the "technologies" in the 3.5TT, that's the one that causes the most actual problems: sooting, fuel dilution. And, I bet the 5.0 is gone from the truck, by the time it's offered in the mustang.

LOLOLOLOLOLOL.
