How can I download GB english version onto Italian Win 7

From Download site I selected 6.1.3. which installed in Italian an I get it to install in English.

Read these guidelines and ask a good question. What do you need really? What is install in English?

You can download the GB installer from this page.

We have a single Windows installer for LibreOffice (not for help packs!) which contains all the languages in the package. You only need to select the required UI languages when installing, using custom setup type.
