actually does any one know what varient of rd33 is the fc-1 fitted with?
other option was RB-199. T:W ratio at 7.5 ( compare to M-53 6.5) not bad.

The RB-199 is certainly small enough and there are variants with afterburners (although their total thrust is lower than the RD-93s but they probably have a longer lifespan than Russian than Russian Turbofan engines) but like tphuang said, every indication is that Chengdu would prefer the WS-13 engine.
