Early S197 Coyote swap.

[Mbara80626]

Hello Everybody!!
I'm new to the world of Coyote and S197's so some info would be appreciated I have a 09 Mustang GT with a 3V and have the opportunity to pickup a Gen 1 Coyote. I'm not looking to build a monster just a daily driver. The info I received about the engine is its out of a 2011 mustang and it had a misfire issue.. What are the know issues with the Gen 1's.
Thanks

You'll find a lot of helpful information about Coyote swaps on this page:

2005-2009 Ford Mustang Coyote 5.0L Engine Swap

I'd also recommend you look up our resident Coyote swap guru Matt Soppa on YouTube. He has an excellent series of videos describing a Coyote swap into an 05-09 GT.

As for the misfire the most likely causes are either a bad spark plug, COP, or injector. Before buying any engine with an unknown history, a compression check on all cylinders is crucial as this will determine the general health of the engine. Otherwise there could be a mechanical cause of a cylinder misfire such as a bent/burnt valve, a broken cam follower, or a damaged piston that you'd miss if you didn't perform a compression check.

If a compression check isn't possible, pull the plugs and examine the cylinders with a borescope. The no.8 cylinder on early Coyote engines has a tendency to run hotter than the others, and some would develop premature exhaust valve guide wear or detonation on that cylinder.

Generally Coyote engines are robust and reliable but like any engine, a timing job will be required at some point depending on how the car it came from was driven. Buying any used engine is a gamble but an inspection under the valve cover, and a check of the oil colour/quality on the dipstick will give you a clue as to whether the engine was properly maintained.

Thank you Dino!!

Thank you Dino!!

It's been a bit since visiting here but thanks Dino for the plug and feel free to contact me directly ( not thru here, it's clumsy ) about the swap and our plug and play swap harness!

Hi Matt!! I will definitely will. Thank you.

Hey Everyone. Question. The Gen1 engine stated above fell thru and I was able to get my hands on a gen 2 engine from a f150. What needs to be changed to use the Gen 1 ecu? Phasers, Cams ,Exc? Thanks in advance for any help.

Just the gen one cams and phasers

On gen one ecu you do mean a gen 1 coyote ecu correct?

Yes

One more question on transmissions. I want to use a 6R80. I know use a MT!! Lol. I have a bad left knee. So anyway does it matter if I use a gen1 or gen 2 6R80 ? As usual any help is appreciated.

Yes. Need to use a gen1 6r80 with a gen one ECU unless you change the valve body in the 15-17 6R, but don’t quote me on that. I’d just get the 11-14 6R

You can use a gen 2 6r, but it won’t shift perfectly. It can be tuned to shift correctly but most tuners won’t deal with that. You can swap a 13-14 gen 1 valve body on to the gen 2 transmission. That will allow you to update the solenoid strategy correctly so the transmission has the right baseline to start with.

Will Gen 1 F150 cams Work?

Will Gen 1 F150 cams Work?

Yes. They do not produce the same horsepower as mustang cams though. They do, however, make a lot more torque in the low-mid range.

 

[Dino Dino Bambino]

Will Gen 1 F150 cams Work?

You can use the Gen 1 F-150 exhaust cams because those are the same as the Mustang exhaust cams, but you'll definitely need the Mustang intake cams when running the stock 11-14 GT ECU.

Will Gen 1 F150 cams Work?

Gen one f150 exhaust cams are the same. Intakes are different
