hey, whats up! that is sweet that you are doing that to a z32! do you have a RB25det? right now i have a front sump on it but that wont work with the cross member and if you find a rear sump online they are crazy expensive. So I was thinking about converting my front sump to a rear sump myself but I found a guy on here, which I believe his name is PAT1, but he makes them from scratch. SO i will prolly send my front sump to him and ave him convert it to a rear sump. With the mounts, since the RB25 mount are only 18" apart and the z31 mount are 22" apart, i am going to fabricate a plate to bring them in 2" on each side. Also with the z31 mounts they are at the wrong angle, so i am going to cut the engine mounts down 2" (for hood clearance) and at a less steep of an angle. There is a guy on here, i forgot what his user name is but his real name is Jason Ritter, he did the same thing i am doing and he has pics of pretty much every step. When i bought my RB it came with the wire harness and the ecu for it too so that is what i am using for the engine management.
