I can't remember the protocol the 370Z uses (should be an easy Google search) but, nowadays, it's getting hard to find an adapter that won't handle all protocols (or at least those you're likely to run into).
Edit: They both use the ELM327 (a very popular chip), so their capabilities should be very similar.
Edit 2: According to my ScanGaugeII, it's using CANSF. "Finally in 2008 all vehicles originally sold in the US or Canada were required to use the CANSF protocol." -
