1) Read every single thread in this section:
Turbo Guides - SR20 Forum
Read them twice and take your own notes. Hell, print them out and highlight sh*t.
2) Then read every single Sticky at the top of this Section:
http://www.sr20-forum.com/turbo/
3) Then go buy and read a book, "Maximum Boost" by Corky Bell.
4) Then use the Search function to answer any other questions.
5) Then when you are reasonably turbo-educated, report back to us with
your plans and ask any remaining questions that you did not understand from
your reSearch.
After you have followed that outline above, you will willingly and happily receive all the help, expertise and professional advice from this forum you could possibly hope for.
