You'r basic problem with turbocharging a carburettor is that carburettor work under negative air pressure. Trubocharging is actually the opposite.
To sole that problem, you'll have to get a carburettor of a cb23/61 Daihatsu with the surge tank and piping. Get the turbo if its in good nick, but i doubt it.
You'll have to fabricate your intake manifold to house the carburettor and your exhaust manifold for the turbo. Intercooling is advised but not necessary as you won't be able to run too high a boost!
