um, to turn tubo even a low pressure conversion.
You firstly gotta find/fabricate and exhaust manifold that will house a turbo, then you have to modify the existing exhaust system, then fabricate an inlet system, plumbing in all the needed pipes. After that, you need to sort ignition curves and fueling, are your std injectors up to it? do you need a 5th, do you want to mess about with a 5th injector setup (crude).
Then there is more to consider but i cant be arsed, its just not worth it.
