I haven't fitted uprated ones but have removed the standard ones, I just put car on ramps and supported sump with trolley jack, I then unbolted the mounts and lifted the engine a bit was not a problem, I can't remember if I removed one side at a time though as been a while, as I also did similar when I removed my sump as had to jack the engine up then to get it out. Shouldnt take long to do though
