is there a way to get a turbo to work right without completely redoing everything...like just bolting it on, or does all of the work have to be done?
model, make, year, engine size, etc?

from what i can tell you have the DOHC which put out around 220hp stock, the twin turbo models use the same engine(276-321hp) but i'm not entirely sure what is dialed out on it, your probable best to go to one of your local performance shops and see if one of them know or can check the turbo requirements.
Yes there are turbochargerkits that just bolt on to your engine.But they only give you 4-7 psi of boost.which is a safe boost range for an high compression engine. If you go any higher you will start breaking internals. If you take a look at the turbo version of your motor, you'll notice that they have beefier internals plus lower compression pistons to withstand the boost that the stock turbocharger gives out.
