I couldn't find any repair manuals in here, so here is mine.
This one is for 350Z EUROPE, but still works for our cars.

There is a lot of words in Russian, don`t worry about it. Just click on the "z350_Z33_04_05.rar" link and download will start.
After download, unpack the archive with a winrar and enjoy.

 

Google and you'll find quite a few sites that have the US versions available for download. Yours appears to be just for 2004.5/2005 based on the file name. Those other sites will have almost every year.

 

Yes, but I figured it would be nice to have one in here since this website is actually about this particular car. Or how about finding the most comfortable one to work with, and post it here? So you don`t have to spend half an hour searching for it.
