2009 Nissan 350Z car

If you're interested in doing some performance mods and your own work on your car, you're better off purchasing a "Single Vehicle" subscription to an on-line service like Alldata, Mitchell 1.

They cost between $25-$30 bucks for a year access, and are much better than any written manual.

Information for your car isn't currently available through Alldata, but if you contact them, they'll be able to tell you. I don't know about Mitchell.
