hey, first off i have a 89 240sx with a Ka24e. i've been looking into a ITB set up for a while, and the least painful way i've found for a FI car is to convert to carbs. i found out that nissan motorsports makes a intake man that bolts up 2 44mm Mikuni dual carbs. i also hear that mikuni doesnt make these carbs anymore, this true? if so is there another dual carb that will bolt up? and then what about the fueling, how does the fuel get into 2 carbs? and is there a return line i have to rig up? well, thanks
