Why are the 1NZ-FE specifications different on different websites? I need to find the correct specifications. Where do you usually look for engine specs?

You are probably looking at information on sites where the content has not been updated in a long time. Or there is just a mistake. Can you give me a link? I'll check it out. For detailed description and specifications of the 1NZ-FE look at wersis.net, we have been using this site for many years, the information is correct.
