turboing a carb is going to be a pain in the butt. Tuning the fuel is going to be a nightmare.
First I would get a weber carb, tuning that is going to be a lot easier than tuning the stocker and they flow a lot better. (I have one for sale if your interested lol )
you'll also have to make some sort of pressure box around the carb i think so boost doesn't leak out the idle screws and such.
you also need to plan out how to get oil (and possibly coolant depending on the turbo) to the turbo
you have to remember this is "different" because it's a pain and not really worth it so no one else does it
