||This swap is getting popular with the FC3S crowd as more used JDM engines
start to trickle in from Japan.  The FD3S is one of the strongest selling
sports cars in Japan, making used engines plentiful.  With upgraded internals
and stock twin-turbos, more power is not a problem with this engine!
|Cosmo 13B-RE 2-rotor:
||Although not one of the more popular swaps for the FC3S, it could be gaining more
popularity due to the lower cost and ease versus all of the other non-13BT swaps
|Cosmo 20B 3-rotor:
||This is the "big block" engine swap for the FC3S.  Adding another rotor
increases torque and power output!  Originally from the Japan-only Mazda
Cosmo, this is one of the ultimate rotary engine swaps for the FC3S.
