To be determined as both engines are fairly new. Here is how I looked at it.

The 5.0 and EB are basically the same off the lot with the EB having a negligible advantage in fuel economy and power. The EB is still a V6 and is for all intensive purposes maxed out on what can be done with it. I know there is still some room in the motor, but it already has a power adder.

The 5.0 is shared between the F150 and the Mustang. The Mustang is a popular car for people to play with for all kinds of racing. This means to me that if I want more power, I can find a ton of aftermarket upgrades which will allow me to get all the power I want (570HP, 530lb-ft from Roush, 600HP from Hellion)

Lastly, from a pure engineering perspective, the EB has more room to fail as the turbo system will eventually breakdown. It has a lot extra plumbing and other parts which is something else to wear out. I'll be interested to see where the 5.0 and EB dyno after 100K miles. The turbos will degrad over time, just a matter if it is more than the 5.0 has issues.

I chose the 5.0, but I can easily see someone picking the EB for a lot of good reasons.

No doubt the 2011 and 2012 Ecoboosts have been the most problematic engine out of the 4, but it is almost entirely due to the issue with the intercooler. Very few (if any) 2013's built after Sept 18, 2013 have experienced the issues, so it seems like the Ecoboost is now up to the reliability of the other engines. Long term, who knows. But for now, the 2013's definitely seem to be on par.

I do not tow much, so the ecoboost wasn't necessary for my application, however if i do ever tow something the 5.0 will be more than adequate. I have a supercrew xlt and before lift and tires I was getting 19.5 mpg. My 06 tacoma only got 18 and was a friggin reg cab! I too test drove the ecoboost and knew I couldn't go wrong with either engine. Just for my purposes, I couldn't justify the price difference for the eco.

In terms of all the issues you hear with the eco... you are going to hear more bad than good on a forum and everyone is going to be biased towards what they chose. Test them both out, consider cost, and enjoy your new truck!

I like the Coyote. But a guy at work has an EcoBoost, had transmission problems and the dealer gave him a new truck which he chose the ecoboost. He feels it pulls like no other, with good fuel economy for a truck. Although when pulling a trailer he says the stress on the engine causes same mpgs as a V8. I personally don't like the idea of maintaining a twin turbo long term as to an old fashion v8. It seems like the dealer would be less labor wise working on a v8 in general as to the Ecoboost.

The coyote is far from an old fashioned v8.

They 5.0 has its advantages over the eb, but...

Sorry, but this is far from correct. Go and see what's been done with 2jz's, Buick 3.8's, and fords Australian turbo 6. Double to quadruple the stock hp without additional "power adders" or even modifications to the long block.

Turbos don't generally degrade over time, unless you're running in an incredibly dusty environment...with no air filter.

The 5.0 litre engine is a 302. ie it was used in the nineties and 60's mustangs etc. My point is that the concept of a V8 on a Full Size pickup platform is nothing new if anything it's where things started.

engineermike

You DO realize the 2011+ 5.0 is a quad cam, 32 valve, tivct modular v8, not the cam in block, pushrod, 2 valve v8 of yesteryear, right? I'm pretty sure they don't share a single part.

engineermike

Fwiw, the concept of putting a 6 cylinder in a truck is just as old as putting a v8 in one, and turbocharging and direct injection were around 30 years before either one of those happened.

Fuel economy, yes. Power, not close. The EB and the 5.0 are not in the same class. The power difference is demonstrated in the Tq/Hp curves. The power difference to the butttdyno is equally demonstrative.
