I’m looking at engines to switch mine out and found one that is in a 15 crosstour, it shows it’s not compatible. Can anyone tell me which engines would bolt in without having to do anything else and without having to change wiring harness and pcm?

Also what heads are interchangeable with J35z2? If I could find heads that don’t have vcm and the cam isn’t prone to deteriorating like the ones I have now , I’d go that route too. This option I wouldn’t mind switching harness too. I would I need to switch pcm in this case or could I just get mine reprogrammed? If I have to switch PCM, I would need the donors, ignition w/key and immobilizer in order to avoid it not starting right?
