Well, if you dont want to go with the crappy boring single carb. Get a factory twin downdraft from australia.:)

Check out sigma-galant.com It's a aussie site that has to do with all teh early mitsu cars n what not. They got the twin downdraft carbs, hell fo a upgrade from a single, adn twin sidedraft manifolds n what not pop up quite often. They even had a Factory suck through carb setup on teh turbo sigma. Might be worth checking out if you dont want the run of the mill single carb.
