This is an advanced technical forum, and a basic knowledge of automotive workings is expected from anyone posting (It's one of the forum rules even!). If you really need to know which port is which on a standard turbo then Google is where you should be looking.
I hope you post your build as it progresses, but please exhaust your resources (i.e. Google) before asking any basic questions here. The forum admins, and knowledgeable old timers don't look kindly on anyone too lazy to reach out and find information for themselves, especially when it is readily available.
That said, there is a wealth of information to be had here; Search is your friend, 99% of the information you need is already here!
Edit: Feeling generous, see the link below, it should help.
