Can somebody tell me the difference between the non-turbo engines offered in the 2nd generation RX's. I keep seeing reference between the FC and FD and I have know idea what the hell everybody is talking about. If anyone knows stats like HP and Max RPM that would be greatly appreciated.

 

ok -

FD is a 3gen sometimes called a batman coz they look the batmobile, they are all twin turbo from factory! and the around 220-250 horse

FC is the 2nd gen they are turbo or na, the turbos up run a single turbo setup and run about 170 horse

the na run about 110 horse

i cant remeber the ex. horse but i think they are close but i dont know! but they round bout there!

 

DJ! is more or less right, but maybe the numbers differ slightly in New Zealand.

FC are the 1986-1992 RX-7's, also called 2nd generation RX-7's. They all have the 13b engine.

They are divided into:

Series 4 (S4, 1986-88) with 146 hp@6500 rpm 138 ft lb @3500 rpm
Series 5 (S5, 1989-92) with 160 hp@7000rpm 140 ft lb@4000 rpm

Both series had single turbo versions, called the Turbo II. S4 with 182hp/183 ft lb and S5 with 200hp/196 ft lb.

The FD, is the 3rd generation of RX-7's. They are all twin-turbo 13b's. They have 255 hp and 216 ft lb.
