They are much lighter then the VG/RB Engines. Infact I remmber a old comparison article that was floating aroung the web somewhere, where it was concluded that the VQ35 didn't weigh more then 45lbs more then the SR20 (with the VQ30DE weighing in less then a SR). Add to that , the fact that this VQ is about 85% new when compared to the previous VQ35 ..... VQ35HR - The Nissan 350Z Wiki

This forum has changed alot, I guess 240sx-tech or Pole Hunters would be a more suitable name for this forum.
