Found some parts dealers with service / part diagrams posted on the web, and came across this interesting bit.
There is a differentiator for a 3.3L w/ sub-radiator & 3.3L w/o sub-radiator. By looking through all the parts diagrams, this sub-radiator feeds the air-to-water intercooler. When the sub-radiator isn't used, water is sourced from the main radiator. I am fairly certain this is one hardware difference between the base and higher output engines, which makes sense from a reliability standpoint.
The only reason to have this differentiation would be the additional heat management coming from the higher output engine.
EDIT: It looks like this guess is likely incorrect. Additional radiator appears to be tied to towing capacity, as there are the two lowest trim non-S models that have a lower towing capacity.
Other interesting bits of info from the powertrain.
Only one turbocharger part number.
There may be two part numbers for engine short block assemblies. They are so close together though it could be just a notation thing. Only appears to be one part number for a long block though, so leaning towards the internals being the same between the two engine variants.
Approx. long block cost is $9300.
Approx. transmission cost is $13k.
Front differential is mounted to the oil pan (with one half-shaft going through the oil pain) like a RB26 (R32-R34 Skyline GT-R).
I cant find anything on the wet-clutch pack or MHEV motor, I am assuming that may all be baked into the "transmission" considering its outright cost.
It would appear it goes engine -> flywheel/damper -> transmission (Wet clutch pack->DC Motor-> transmission gear shafts -> transmission output shaft) -> transfer case (center diff) -> front / rear diffs.
Just drawing conclusions on this setup based on notes for the 3.3 and the 2.5 phev that have been released thus far. This would mean the transmission likely is a true automated manual (single clutch, not dual clutch).
The transfer case / center diff resembles a 4wd transfer case, which means that the RWD link is likely mechanical (in an AWD failure mode, drive may become 100% RWD or a high split 80/20) and the FWD link is likely parasitic to the main drive line (hence the rear-wheel drive biased).
