Usable turbos

I have a 1.4 sport plus and have decided I want to turbo it, done a search but nothing seems to relevant.

What are the potential options as far as turboing goes?

I assume any or the t20 t25 and t28 variants? What about the audi k04 and similar?

Also I plan on getting a second hand turbo to keep costs minimal so any advice what vehicles come with these turbos would be great!

Thanks in advance
