Q: Lion on a Nehalem Mac Pro 5,1?

I upgraded to a Nehalem Mac Pro and am running Mavericks. I am using a main drive, data drive and backup drive. Can I load Lion on a 4th drive so I can use some apps that won't run on Mavericks? I put a CD with the Lion installer on it and got a message that said "This version of Mac OS X is too new to run 'Install Mac OS X' from Mac OS X 10.7." Is the problem that the disk is incompatible or is the installer incompatible or is Lion incompatible with the processor?

Mac Pro, OS X Mavericks (10.9.5)
