The below oil cooler came with my 20B. From looking at a lot of pics online I think it is an FC one?
(http://i157.photobucket.com/albums/t59/Leeroy_25/Mazda%20RX7%2020B/OilCooler_zps8e2c8cea.jpg)
Would the aftermarket version of one of these be sufficient oil cooling for the 20B or do I really need to be looking at something larger. I would say the capacity must be fairly similar to the FD twin coolers due to its size?
Thoughts? I am just toying with what options I have for the moment..

That\'s definitely an FC oil cooler - they are very large, I think the capacity is bigger than that of the twin FD setup.
They are quite fragile where the thread is for the banjo\'s though.
