Excellent question. Both have virtually identical internals but very different prices.

I'm sure theres more involved in it than that as well.
Yes, it's less work to just start off with a RWD VQ. But the reason why is the price difference between the FWD and RWD motors. Go search ebaymotors and you'll see what I'm talking about. Typically RWD motors start at $1800 not including transmission. You can find FWD VQ35 for as little as $600 sometimes.
From the guy that actually did it:

A custom exhaustAn ABS source IE an ABS diff or abs spindle to get a Speed signalDakota Digital Converter to convert ABS pulse into speed pulse. To 'smog' the car or ref it and get it BAR approved you will need the catalytic converters from a RWD plat formSmog equipment from the car you took the ecu/bcm/nats/key fromyou may need an IPDM depending on the ecu you use. You will need to upgrade the fuel pump to a 300zx or Q45 or a walboro 255lhrYou will need an aftermarket FPR preferebly a nismo or aeromotiveyou can use a FPR off of a VQ30 but you will need to modify to fitYou need a DBW gas pedal obviously if you use a DBW VQ ECUthe one from the z33 and the 5.5 gen and 6th gen maxima work
It is cheaper to use the FWD motor is the long run, but possibly a bit of a headache to source parts. However RWD motors did seem to be a little cheaper than the last time I looked...
