I currently have a D16Z6 in my 92 Civic Sedan and am planning on getting a B series engine from a friend very soon. Will all the B series engines fit right in or will I need to get different mounts for the engine. I want a B16a, B16a2, B16b, B18c1, or a B18c5. Will they all fit in my engine bay with no problems? Thanks to all that respond.
