My experience and suggestion is that you spend a year or so reading before you do ANYTHING. Enjoy your NA (normally aspirated) car the way it sits.
I've looked back at some questions I asked in the beginning and boy was I lazy, selfish and ignorant.
If you want a turbo car, go buy one and enjoy it as it sits. You will learn and save yourself so much hassle if you take it easy and take your time.
Set yourself some goals, both HP related and financial as to what it will take to get to the HP goal.
If you don't want to do that, it's okay, but be prepared to struggle and possibly not get help. You will get the "It's been answerd before..." remark and "Search, it's all here.." answer.
Enjoy, your car either way and welcome to the Best Z site ever in my opinion!
