Does anyone know wher I might be able to obtain a dual webber set up for my b230f? I am also considering building a custom built Mikuni set up hopefully I can get some more info on this as I am leaning for a rally motor NA set up for my car. I love the sound and I'm used to tuning carbs.
If I go with MIKUNIS what size? I'm sure a 1000cc bike set up would work just fine and I have read that they will out flow webbers?
The easiest route for a car swap is the webbers but I can't find the intakes here in the states?

 

Anyone done the carb route on a 2.3?

 

Are you looking to do dual DCOE's. Alfa Romeos used these on the Veloce models. Can you find the intake manifold that mates DCOE to a B230f? I think that would be the preferred solution if you can find the parts and they are affordable. I think your other idea is to use four Mikuni's from a bike. This may work because even though the displacement is twice the bike, the bike engine revs far higher and the air intake may be similar. It is also likely that jets and venturis are more affordable.
