That's pretty good, although I've heard of other people (not on the internet) having long lasting older 5.4's, they are pretty solid.

I'm surprised the 5.4 got as many votes as it did along with the support in the comments.... I didn't think many people would have voted.. I was thinking maybe 5-10. I have the 5.4 myself right now. coming up at 151k miles the engine has not been touched other then just doing Plugs for maintenance and still runs great.. Still in the decision making of trading it in next summer for a 5.0 or keeping my 5.4. I'm not sure if I'd want an Ecoboost truck or not.. I heard Turbo failure is an expensive fix.

Heard of a lot of turbo failures have you? I haven't heard of but a few.

Each turbo can be had for about $500 each. Install is pretty straight forward according to the manual. 'Course, you could have the ext-warranty.

People get scared about "advanced technology". Truth is, turbos have been around for many decades. So really they're "old technology", and very trustworthy.

Stick to the facts man.

I have driven all the motor combinations and for the v8's I would choose the 5.4l 3v as long as you get it tuned. It reacts the best to tuning for the n/a motors and had a great flat torque curve.

Other then that the EB is a great motor, but I just love the sound of a v8.

More expensive than cam phasers?

Seriously...

I had the 4.6 in my 2007 f150 and it actually took me about a month to figure out it was a V8. After test driving it, I assumed it was a 6 cylinder because of how underpowered it felt and how quiet it was, it wasn't until i was looking at the door sticker that i found out it was the 4.6 v8. Not sure how reliable that thing was cause i got rid of that truck after a few years, but man was it terrible performance.

Got the 5.0 in my 2012 now and it's a world of difference even in stock form. Waiting on tunes from 5 star now to really open it up.

Turbos used to require a lot of care and needed to be spooled down, cooled down etc either manually or with turbo timers, but now a days they're so common and the technology has advanced with them being water and oil cooled even after the vehicle shuts off, you dont really have to worry about that


Forced induction, however, comes with a lot of caveats that you can't really get around (high crankcase temp/pressure, blow by oil vapors via PCV, detonation, etc). After owning a turbo'd car last go around, I feel like it's a highly orchestrated ballet of factors that make a turbo motor healthy, and if any one factor goes awry, it affects everything else in a major way. At least with the Fords they had the sound mind to make them MAP/density based and not MAF based, which causes a whole 'nother set of clusterf*ck issues and constantly chasing down boost/vac leaks.

Oil choice is also a really big deal in turbo motors due to said blow-by, and shearing due to high temps, etc.

I've had both the 5.0 in a 2011 fx4 and now the 6.2 in 2013 fx4 and I can say that the feeling and sound of pushing the pedal on the 6.2L v8 is hands down much more enjoyable.
