I bought my e21 with webers, and i am doing a conversion to itb's and turbo with megasquirt over the winter. i am curious what i should sell the weber set-up for. they are dual sidedraft 40's with karzundpartz manifolds, used but in perfect working shape. i have no idea what size jets or other options they have, but the car runs great, and they sound awesome. i am hoping some of you veterans have seen this set-up sell a few times and can give me an idea of a fair price., thanks.
