How feasible is it to swap a Sky-activ motor into a 2nd gen Mazda5?

Like the car, but am disappointed Mazda didn't have a 3rd gen with the Sky-activ 2.5L engine. Would've been a perfect commuter imo.

How difficult would it be to swap in a 2.5L (or 2.0L even) engine with the Sky-activ 6-speed auto as well into the Mazda5? Apparently it got these powertrain combinations overseas.

Probably easier to see if you can get a front cut from Japan and install that.

In reply to Dootz :

I would imagine this is as large an undertaking as the Boss Wagon MazdaSpeed5 Project that was attempted 10 years ago by Car And Driver.

Orange Virus had a thick egg to crack when they tapped into the ND1 Miatas in 2016.
 

I'm one of the other 12 people who would have been swayed into buying a 5 if it were offered with this motor instead of the mzr.  Because fuel economy. I'm pretty sure iirc they offered the skyactiv motors in that same 2nd gen that was sold here.  But not here. Naturally.

They offered the 2.0 skyactiv starting in 2013.  Same chassis as the mzr looks like.  May not be as hard as you think? 

The 2010-2015 is what I call "second gen" perhaps incorrectly.  Since there is a 99-04 one that never made USDM.

I'm guessing this is a problem that can be resolved by applying an appropriate amount of money. How much very much depends on what's different - I would suspect that you need the whole drivetrain and the associated ECUs, then hope that those speak the same CAN bus dialect that makes them integrate with the existing ECUs and wiring loom without lighting up check lights you didn't even know you had and do funny stuff like putting on turn signals when you try to crank up the volume on the radio.

You may also have to update the fuel system to be compatible with the GDI system used on the Skyactiv.

While all that is doable - all it takes is time and money - is it really worth it?

Bolting in is easy.  Making the electronics work is hard.

 Direct injection means that, for now at least, you are married to the original engine controller and all of its dependencies.  One of my favorite examples of how bizarre the dependencies can be, was the pallet of everything you need to make a Hellcat engine happy.  On the pallet besides the steering column, dashboard, fuel tank, and such... were the taillights.

That sounds like a lot of work for very little gain.

I think the roadkill guys ran into this tail light issue with a hellcat swap into a 70's chassis.. and had to defer to hellcat swap experts.  BUT *if* you are able to get the pallet of skyactiv 5 everything, I think you should be good to go. The tail lights would at least bolt right in the USDM 5.  :P 

I think Mazda missed the boat by not doing this from the factory..
