You are best off getting the radiator and hoses from a parts website, mishimoto is the cheapest one you can get. The plug conversion isn't really an upgrade IMO just looks cooler but the cheapest and easiest place to find that is at the JY off a 1.8L protege. And the mazdaspeed trunk badge is practically impossible to remove without destroying it so you won't find a used one, best bet is a new one or MS3 style badge off ebay.
