14,000 kgf of thrust is the ultimate spec. This puts it slightly below the 117S (14,500 kgf), but very close.
The Taihang engine is already in-production and in-service with the PLAAF. Note the yellow serial numbers on the vertical stabilizer. These are in-service aircraft.

The Taihang is also in-service with the PLANAF. Note the blue serial numbers. The fact that the PLANAF is willing to use the Taihang should at least give you a clue regarding its reliability. Only a fool would fly an unreliable engine over water.

The next step would be to power the J-10B/C, J-11D, J-15, and J-16 with the Taihang. So like I said again and again on this forum, there is no need for the Su-35.
