Engine altering and turbo prepping

I finally decided to go through with making my d16 turbo charged. Now I just need to start builing my engine up so it can handle some boost (already can take a little boost but rather be safe). I have heard a couple different ways to prep for this such as changing the fuel injectors, throttle body, fuel rail, rods, pistons...etc. I would like to start out with the items that I can throw on after a couple hours of work and still be able to go driving. So...with that in mind, what should I start with first?

Thanks for reading the post
