I wonder...

Would an engine/transmission from 2012-2014 fit in a 2009-2011 genny (either 3.8 or 4.6/5.0)?

Now I am not considering this but thought about it since the Genesis did not have any major chassis change until 2015 if I am correct.

The 4.6 ran from '09 to '12 and 3.8 to '14. The '09 and '12 4.6 are quite similar under the hood.

So my bet is that the 4.6 and 3.8 should fit just fine.

Yes, but all the engine control computers would also have to be swapped out and maybe fuel pump due to the direct injection engines.

Some of the early V8's in 2012 were the 4.6, but replaced mid-year in 2012 with the 5.0 Direct Gasoline Injection version. I believe that all 2012's, even the 4.6, used a brand new Hyundai 8 speed transmission (but not 100% sure), and 2009-2011 4.6 used the 6-speed ZF transmission.

For the 3.8, I don't it would be easy to swap out a 2009-2011 engine with a 2012+ GDI 3.8 engine. Also, the transmission for the V6 was an Aisin from 2009-2011, and 2012+ used the Hyundai 8-speed transmission.

Even if not swapping out the transmissions, mating them up to the engine could be tricky if the gearing was not set up for that particular engine.

Yes the '12 4.6 has the newer 8 speed tranny.

The door sticker on my 2012 4.6 says the car was built on July 25, 2012, which would seem to indicate that 4.6's were also built late in the 2012 production run.
