VQ 37 engine need advice

The crate was damaged along with a few plastic connectors on a couple components and was refused by the dealership and sold in a freight liquidation auction. I'm not sure of the official names of all of the parts damaged.
I have it pictured on e Bay item 290364569914 and am hoping I could get some further information on what models it fits.
I found out through Google that it fits a G37 but am confused as to what other models of the 370Z it might fit and what the lower case b means next to the VQ 37
Any and all input would be appreciated.
Thanks for your time
