they are lying basically..
it's really same as any other RB25/20, you take off the intake piping to the throttle body, disconnect a few hoses and remove the valley cover - only real difference is there is a few more hoses..
i removed and replaced me coilpacks in my r34 in just under an hour a few days ago, for mechanics that are meant to do this shit every day it should be a peice of piss.
