    Project Kickoff, August 1st, 2019: We are working on a swap in our shop and felt it was a good idea to share what we have learned. This is also posted under the "engine swap" section where I have posted some questions as well.

    We have worked on a lot of Coyote powered cars over the past 9 years since the engine debuted in the 2011 Mustang, but have only worked on two Coyote swaps - and both were initially done by other shops. Both the E92 BMW (above) and Fox (below) swaps needed a LOT of clean up work and durability upgrades, which we tackled. The E92 became a proper track car after the work we did and the Fox became a much nicer, more functional street car.

    We have done dozens of LS swaps in-house and sold hundreds of LS swap kits. Why LS swap vs Coyote swap? Two reasons: COST and SIZE. A built Coyote is pretty damned expensive and for a road race car might make 500 whp, but they are usually short lived. You get it past 5.2L and you spent some SERIOUS money. A Built LS is common and can go to 8.0L inside an OEM block (and 8.7L in tall deck). I'm not guessing, we've done this, a lot, at my engine shop Horsepower Research. This image shows the size thing...

    I'm not arguing for LS swaps, just have to always put that out there as a warning. Now we have a customer that asked us to upgrade his 2010 GT which had the lackluster 4.6L 3V engine. 300-315 hp, makes 260-280 whp in NA form with some headers, CAI and tune. Wee!

    [​IMG]

    He wants to move out of the class he was in (NASA Spec Iron) to a class that allows +100 whp (American Iron). Our suggestion was to over shoot the ~370 whp the class allows and go for a Gen 2 Coyote swap, make 450 whp, then use the electronic throttle to restrict the tune to make a "flat power" 370 whp across the board. Old trick, really works. Uncork it for fun events and let it fly!

    He went with a Tremec T56 Magnum XL, ARH long tubes, Gen 2 crate motor, and the Ford controls pack.

    We have found a lot of part numbers for Gen2 specific parts we need, made a lot of little brackets and doo-dads to make the Controls Pack bits fit, and have the swap mostly done. I will post more here as work progresses. We currently are looking for these solutions:

    1. Making the stock gauges work (doubtful - will likely use AiM digital dash)
    2. Get some ideas on making a 2011-14 EPAS electric rack (Boss302R rack) working

    The wiring and CAN comms are always the hardest part of any swap, and this looks no different. Except that there seems to be only ONE source for a wiring harness to work with the OEM computer (Ford). And there seems to be no way to make one street legal (which is what about half of our LS swaps end up doing).

    More soon,

    Super excited for these Vorschlag builds. Always fantastic and reliable info. Will the coyote s197 wiring harness not work with the Gen2?

    Why not just use the AEM Infinity ECU? I think they have a Coyote harness.

    Well.... possibly? Even if a 2011-14 GT engine harness could work in a 2010 car with a 2015-17 engine (it probably doesn't) you'd still have to extract the entire harness from a wrecked 2011-14 GT... lots of chasing your ass doing that, trust me.

    AEM could work, for sure, but it would need an engine harness made for a Gen 2 Coyote + the same or more work for integration into the chassis and digital dash. Customer isn't looking for that level of power / tuning potential. 430 whp is the stretch goal. Reliable, easy to drive road race car.

    Since he wants an easy swap, and he has a good hook-up on Ford Racing parts, he supplied the Ford Gen2 computer + engine harness. With a couple of custom tunes loaded on a handheld tuner like an SCT, he can swap between the AI legal tune (throttle restricted) and a "more powerful" tune in less than a minute trackside.

    The Ford Racing harness is production quality and routed perfectly for this Gen2 engine, cannot complain there. I've seen some aftermarket EFI "engine harnesses" show up with a bunch of work needed to complete them. This is pretty much plug-n-play.

    We have knocked out a bunch of steps on this swap - mounted the auxilary fuse box and PCM from the Ford Racing kit - and I need to spend a weekend catching up on build thread posts!

    More soon,

    What all do you add to an otherwise stock Coyote motor to make it reliable enough for severe road course duty?

    Shoot, its a private video.
    PBH is coming out with a harness that addresses this and all the gauges etc. will work...stay tuned.

    Oil cooler, better radiator, and never rev it over 7000 rpm! :p

    If I ever lose my 3V 5.0 motor in my '09 GT, I'll be talking to you about a LS2 install project!

    Yea, an LS sure makes things easier! This is our S550 chassis with the beginnings of an LS swap...

    We have made great progress on the Gen II Coyote swap on the 2010 GT. Waiting on some long lead time items like custom fuel cell, some wiring bits just arrived, oil cooler system being added, etc.

    Will try to make an update to this thread this weekend.

    Everything looks good except for the JLT cai. PMAS has a cleaner maf signal.
