Foreing questionings, Sentra b13 Ga16Des (carburator)

hi, i'm new here but i'm triying to get all the info that I can to make my Sentra made in Mexico B13 95 Ga16des SuperSaloon (carburator). I have 2 ways that i could take but i'm not too sure, 1st to keep tunning my 1.6 or to to get a swap(i like this one mos) .

So what i need is all the info for a sr20 or sr20t swap for my 1.6 carburated, costs, a complete need of parts for the swap and how much it will be in general.Where i can get this stuff (including tje engine).Right now i'm in the states (MIami) and i want to send the parts to NIc and make the swap there so i need all the info that you fellas , could give me. Because i'm Sentra lover & i want to have the first Se-r in my country and kick some Honda's Asses

Another option is to keep working on the GA16des carburated, it already has heaters, a hand made intake for the carb, 2" pipe, hi flow muffler,iridium spark plugs,9mm spark plug wires,. So what i can do next , this Mexican Sentra is carburated and it's a little bit less(95) hp than the american version. What do you suggest. oohh one thing my budget is not a millionary one, u know i mean.

Here in Nicaragua the Street racing and 1/4 mile are very popular and there a few or none, racers that use and put in the top the Nissan Name,specially the Sentra or SE-R. So i always dream to make my sentra 1.6 into Se-R and beat those dams Civics VTEC .

So please give answer my questions, i;m having a hard time triying find help wiht my proyect.

Well thanks for all friends
