I don't imagine it would be too difficult mate
Remove gearbox, disconnect exhaust, plumbing, wiring loom, fuel lines, coolant hoses and radiator for more room
Remove the nuts from the engine mount studs and pull it out ...
I'm sure there's a couple of other little things but that's the most of it
Drain all the fluids first too except clutch and brake of course
Do a GTR, now that's a pain in the ar$e lol
