want turbo!

hi,
i am going to get a turbo kit for my 94 sohc vtec si hatchback. but first i just have some questions. if i buy a kit made for my car, is it going to fit in perfectly without any rearranging anything or taking anything out? if so then what will i need to take out? and how much psi can i boost out ? i am planning on a t3/t4, is that to much for the sohc series? am i going to need new cams, pistons and all that? well this is it for now, i'll see if i have any more questions later.
thank you all,

I will say it politely, because people dont take kindly to these types of posts. You have to do your own research, all your questions depend on your budget and you preference, and you will not know your preferance if you dont do the research. Use google and the search bar for this forum.

just to answer one question that is hard to find. the one about any modification. depending of n the manifold on the kit alot of times you have to grind off part of the block. and the fans need to be cut or buy thinner ones
