I know the first two pics let show the Rx-7 Serie 3 12A oilpan
I didn´t know the rx-7 serie with the deeper 12A oilpan and the option to fit the temperatur sensor.
I've never seen one of those before either..... what's that off?................. could have saved me a load of work when doing the Elford turbo conversion with another way to tap an oil return into the sump without dropping the sump or engine.
