anyone done a coyote swap used more than 12,000mi a year ?

[RT]

Anyone here use A Coyote in their Bronco over 12,000mi a year ?

I'm looking to do a engine swap this year .

I put about 18.000mi +- a year on this rig, so the mileage potential and performance of the Coyote is attractive. But some old threads on Mustang swaps raise concerns with drivability issues ( stalling , power loss ).

I know either way the mileage will never pay off the swap but it'll be nice in the meantime.

tossed up between a fresh 5.0 replacement or a Coyote swap

to get the most out of one of those crate 5.0's I'll need a better upper/lower mass air / throttle body etc.

If I can find a deal on a wreck with a Coyote the cost of the adapters headers etc might not be too much more. I've just missed two deals in the last year.

hopefully the Coyote bugs have been worked out , but would like to hear from someone who drives one often to confirm.

thanks guys
Bob

Don't see why you would have problems with it anything could be made to run high mileage if maintained properly.

I've got the Coyote in my F150. Traction becomes an issue at times so with a lighter Bronco it could be handful. Smooth power though.

Maintenance is always the key. but when your talking about long term life at the power levels of the coyote there will be a lot more maintenance involved. Got to figure they tend to have more parts that will need to be changed or that may even fail.
Overall I dont think there are that many bugs with the coyote engine. But I do see it possibly being more costly over time verse a older 5.0

As for mileage potential well I kinda doubt you'll see much mileage gain if any over the old 5.0./302 Broncos are bricks. Plain and simple. The old 5.0 got around 20-23 mpg in mustangs the new coyote gets about mid 20's Swap either into a bronco and you lose that mileage just look at the f150 5.0 a most of them get under 20mpg and its still more areodynamic than a bronco.
Of course the coyote engines are becoming more availible as these vehicles get into wrecks and such and swaps are getting easier as people are doing them so options are increasing. but Id take a fresh engine over a used wrecked engine.
While add on do help you get the most out of older 5.0's really most are not needed and in almost all cases they do nothing but raise the power band If your driving that much then you will want your power lower. Just my .02

I doubt that any Coyote Broncos have seen 12K miles yet!

I doubt that any Coyote Broncos have seen 12K miles yet!

I will further that with I doubt there are more then 12 coyote broncos up and running at this time (but I bet more are in the build cycle right now).

I've seen that Screaming Demon Bronco project , the claims are averaging 17mpg with the 5sp auto. And driving pretty good
That's what led me in this direction. They've had some bugs but working them through.

I figured the Coyote would be as good , even if I get close that would be great.

I was just hoping to get some insight, if I decide to go the Coyote route what would make it the most straight forward swap coming from a daily driver. or at least one that gets driven often. you know , learn from someone else's experience .
I can still make plenty of my own mistakes of my own elsewhere

I'm still in the deciding process, if I happen across a well done 5.0 it might be hard to pass up considering it would be a drop in with all the plumbing and wiring already in place. true that the upgraded induction would most benefit the top end, I could make due with the stock stuff for a while .

But then there's all the tuning options for the Coyote to think about . oofff

Where's that Tequila ?

Realisticaly when you up the power lifespan goes down and mileage will follow suit. Again most all the mods out there raise the powerband which with a coyote is high as is. No matter what its still a 302 cu engine. The more power you get out of it the worse the lowend will be even with computer controlled timing.
17mpg is pretty good for a 412hp engine. Nothing to scoff over so I digress there. But many people are getting similar MPG's out of the old 5.0 and 302's of course they dont have the topend HP numbers but still decent power.
If your really after more power build a mild stroker you'll get power and mileage should stay somewhat reasonable and still be relieable.
One other thing Id look at is if a engine goes down its a lot easier and cheaper to replace the older pushrod motors than it would be to get another coyote.

Lots to think about. I do remember when I finally swapped to injection after dragging my heels for years. But after seeing it work out for so many I took the leap.

Took a while to get comfortable , but I'm very happy now.

I'm normally coal fired and work with stone tools but on occasion I do look up and take on something new.

I'll be keeping a closer eye on some of these swaps , and pestering you all for info.

and to think a few years ago I thought my last major change would be the transmission
What happened ?? heh, heh , heh,,, ahh the good ol' days

Plenty of coyotes in the F150 well over 100K already and most claim no problems. That said, the 5.0 HO is one durable engine the way ford built it. Hammered the crap out of my 86 with bolt on, then NOS, then turbo and I just tore it down for heads and re-gasketing after 30 years and the bottom end still looks great (some minor wear on mains, but crank only needed polishing, didn't even need to be cut).

I would not shy away from a coyote from reports that is has less low end over a 5.0 HO. Now that I own a 14 GT, base auto and have had some time to play in it, it has more low end than a stock 5.0 HO. My typical driving (sea level flat terrain), the thing is in 3rd gear by 20 MPH and is very tractable under 2000 RPM, in a car that is not that far off on weight of a stock EB.

I've been told the coyote only feels like it has low end power solely due to it's 4 something first gear in the 6 speeds, but put it in sport mode and start off in second, it will still spin a set of pilot super sport ultra high perf summer tires for 30 feet or more (with a fresh trak-lok). A stock MK VII would barely get a chirp many times with an open diff (3.27 gear) and it had slightly more overall gear (again, comparing new GT in second gear), and no engine/tranny nannies to contend with.

Just wanted to bring that up to counter the nay-sayers that typically claim how bad the low end power is on a coyote.

I doubt that you would see enough gain with the Coyote to justify the trouble of shoehorning it into the Bronco.
The Coyote is a taller and wider engine than even the 351W/5.8L.

The people that have done the swap seem to be going for the coolness factor.
Nothing wrong with that but technical merits take second place.

A pushrod EFI 5.0L will give all but a possible small percent for much less expense and difficulty.

Even the comparisons of this Mustang with this engine to that Mustang with that engine are not truly apples to apples.
Not the same weight, not the same aerodynamics, not the same transmissions,...etc., etc.

Anybody using the truck coyote or is everyone using the mustang version? And have they figured out the 4r80 auto conversion from the truck as well?
