We get asked this question a lot so have a look at these threads which cover the basics. I have to admire your ambition though! And I hope you pull it off.
Adding a turbo is a major engineering task and without a kit with full instructions and all the parts you need there is a big risk of blowing up the engine. Expect to spend 50 hours upwards on a project of this type.
This is not the sort of modification you should undertake unless you are mechanically competent and know what you are doing.
It is worth looking at superchargers as these are generally much easier to install than a turbo is.
