Whoa buddy. Lay off the caps a bit. 
There was a guy that turboed his 12A, but he used a side-draft carb. As far as I know, you have to do some internal modifications to the downdraft carbs to make them work under the increased pressure.
Here's the link for the sidefraft job: https://www.rx7club.com/forum/showth...hreadid=116768

This site might be helpful: http://www.rotaryshack.com. Also, please refrain from using all caps. On the internet all caps normally means your yelling, plus it's a lot harder to read/understand what you're trying to say.

the carb you will have to get sealed up and make sure the floats are plastic, not brass.
I hear that rotaryshack does some good turbo-carb setups.
You will also need a bonnet, a box which will go over the mouth of the carb that is sealed as well. The piping from the turbo or intercooler will go into this box and the air will get forced into the carb.
You will need a rising rate fuel pressure regulator, not sure if the one you have is one of those... but yeah. You need it because when you get on the gas as more air goes in, your regulator will have to let more gas in (usually 3-5psi more gas than boost).
Umm... yeah. Thats all I can really think of.
For specific questions the best one to talk to is probably the guys at rotaryshack (600rwhp12a on the forum i think)

Yeah, shutup kid.
Rotaryshack does great work with turbo setups. I don't think he does much work with the holley's, but I know he has made many great running setups with the nikki and weber. He hasn't been at his shop for about a week now though. He has been VERY sick and unable to work, but he's getting better. He can actually talk again. I don't know when he'll be back at his shop, but I think it will be soon.
