I bought these a set of fel-pro lower gasket kit for my 2000 Miata. These are the items inside.



The shop whom sold it to me told me it is for 2000 Miata but however on the fel-pro packing, it says it is meant for 1991 1.6 Miata. See here




Are 1.6 and 2000 1.8 lower gasket similar?

 

After some googling, fel-pro is selling this part number for 1991-2000. So yes, it is interchangeable between 1.6 and 1.8

Please correct me if I m wrong.
