Just a guess here. I'm a mechanic and own a FE. I've considered the same thing and it looks like it needs to come out the front. Maybe pull the "face" off the bus (the parts that unbolt including bumper), drain coolant & remove the radiator & coolant hoses, Remove air duct work, unbolt the cross-member, support the trans (if not removing), unbolt the torque converter, unhook the electrical, fuel lines, linkages, exhaust, etc. Either support engine on a rolling dolly or heavy duty chrerry picker and unbolt the front mounts and bell housing bolts and slide forward.
Like I said, just a guess. Trying to jack that thing high enough to remove from below is going to be a real challenge. Trying to get it up out of the hatch opening and out the door is even a bigger one. I have done that sort of thing (marine mechanic bringing engines out and in through a side door) but honestly unless you have a very agile and strong way to manipulate a 1500lb.+ engine safely I wouldn't try that approach.
Hope this helps.
