EnricoPalazzo, i do know what the *** i am talking about. i did some research on the FCs before deciding on a skyline.
when i mentioned S4 and S5, i was referring to the FC design. S1 to S3 is the old savana shape and beyond S5 is the new infinite shape. jazza08 was asking about RX7 in general and i wasn't sure about which series he's asking about, hence commenting that if he is after the FC shape, he should be looking out for the S4 and S5.
and yes, flooding is common in all FCs, but the engine did generally improved for all 89 model onwards. read about this somewhere. Flooding in a FC is something that leave you stranded and will eat several batteries and starters in the process. It happens when you start the car, then shut it down without it properly warming up. Recommened antidotes are purging all the fuel by removing spark plugs, cranking several times to purge fuel, reinstall plugs, crank again, etc..
and you are incorrect about all FCs Cabriolet being auto from factory.
go to this link, its one of the best links about ALL rx7s.
