thanks again, but does anyone has any pictures for these engines so i can distinguish from each? That is the biggest concern about swapping and i don't know if the shop will actually give me a B18C5 or a B18C1. Also, as far as the molded stamp concern, will the stamp actually shows B18C5 or B18C? and what about the GSR engine, will it show as B18C1 or B18C? Of course I am talking about JDM.
