That's nowhere near enough information about what you're planning for us to be able to give you meaningful help.
If you're still at the point of "I've got this 12A here, I wanna put a turbo on it!" but have no idea what you're doing beyond that, then I advise you to start by reading through other people's build threads (particularly the blow-through threads) to see what you're getting yourself into. Then tell us your budget, goals for the car, your fabrication skills, etc.
If you're just looking for some more power, I personally recommend buying a complete 13BT, wiring harness, and ECU from an FC. It'll save you a lot of headache and probably money as well.

its a bone stock 12a that hasent been ran in a year. my goals arent anything beyond turboing it i only aspire to reach about 300 hp maybe less than that. my fabricating skills are pretty decent and budget dosent really matter seeing as its a build im willing to pour every check in. im already pretty self aware im going to have to tear the engine down and get all around better seals that can handle the stress of the turbo etc im just curious to what exactly i need for the turbo set up besides the obvious

The only non-obvious things I can think of would be ignition upgrades, and you'll probably want to do something about your fuel tank to make it more slosh-proof (adding a surge tank, welding in a new sump, switching to a fuel cell, whatever). Of course there will be other things depending on whether you're going to use a carb (and which carb) or EFI (and which ECU). Drivetrain upgrades are advisable, depending on how gentle you are with it.
Other than that, it's like putting a turbo in any other previously NA car. Redo the exhaust, upgrade the fuel and cooling systems, figure out a way to get oil (and maybe water) to and from the turbo, install your intercooler and charge piping, and tune it.

I've never turbocharged a down draft carb, but with side draft carbs its eazy...
Just put a piolet tube from the after turbo piping into the bowl. The incoming presurized air will presurize the bowl with the same presure as the venturi.
OR you could build a boost box around the carburator. (thats what I plan on doing whenever I have some extra time and money)
AND there is the option of draw through, but I'm gonna get an earfull about safty concernes of drawing through a carburator. Also, you cannot use an IC in a draw through setup... also, some of the newer turbos I hear don't have as good of seals to draw through... also when your fuel source is far from the combustion chamber there is more of a lag time.

No need for that with Weber/Dellorto. Just build a carb hat and make sure the float bowl vent is open to the carb hat.

I've done a blow-through DCOE, and I can't really recommend it. If I could do it over, I'd have done a Nikki. Or better, save yourself the trouble and go EFI from the beginning (though that has its own set of issues, at least you'll end up with a better setup in the end).
