what would be the best side draft carb setup for a streetported 12a? i need to get all this figured out so i can start buying stuff for winter. thanks in advance

 

Dellorto or 45mm Weber DCOE.

 

since the weber 45 might be too small I would personally go for the 48 DCOE instead, but the RB holley-setup would probably be both cheaper and easier to install IMO

I have a side draft intake manifold for sale if you are interested. But it is the kind with the short intake runners. If you want a wider powerband, you could go with the intake manifold with the long intake runners that kind of curve over to the left side of the engine.
But to answer your question, maybe a 48 would be better for a streetport motor for better high end power. But a WELL TUNED weber 45 sidedraft might do the trick too. Good luck.

 

thanks i was thinking the 48... so that will be what i will go with. thanks

 

My bad, for some reason I read it as a stock ported 12A. I would also recommend the 48DCOE for your street ported 12A. LEt us know how you like it.

 

I just added a Sterling carb recently. Bolted it on, and drove away with no issues or adjustments needed. Buttloads of power too. Highly recommended.

 

48 Dco

 

hey FBII can you use a 48 dcoe with a turbo setup? im thinking future here.. i heard side draft was better for turboing.

 

I'd go downdraft for anything. IDA setup.

Anyways, as for sidedraft, I'd go with Mikuni Carb instead of weber. (Bikes use them mostly). They are setup just like a weber, MUCH MUCH cheaper, can find parts just about anywhere AND they are estatically easy to tune.
