Allen, Welcome to the forum.
You may have noticed that this forum has over 900000 posts, so you are not alone.
The turbo upgrade has been discussed many times, and some good information is in the FAQ stuff pinned at the top.
My favorite source is www.rotaryresurrection.com Kevin has written up the swap along with a lot of other good stuff.

The complete factory manuals are available on-line.
I have a copy at the link in my sig.
