Carburettor Qs

I have got a single carb civic, i would like to know if i can put the dual carb on my civic? If i could, what needs to be swapped over? Is it just the carburettor part?

if you can find a dual carb manifold that fits your engine, you can do it... good luck with that.

You'll need a linkage to open both throttle plates at the same time, and to link all the necessary vacuum lines.
