4 barrel on a 1.8L? Are you certain about that? I know offy makes an intake that makes that possible, but I've never seen one in use, or heard of one in use for that matter. If you have "stock" carb and have been looking at 4 barrel stuff, that would cause a lot of confusion. If you are sure you have a 4 barrel, then we really need to see some pics of that, and I doubt you'd gain anything at all upgrading to a 32/36 Weber.
The original carb for a 1.8L is a two barrel Hitachi, and the Weber 32/36 kit comes with an adapter plate to fit the stock intake. If you get the offy intake, it fits the Weber directly so the stock carb will not fit the offy intake.
