über das Triebwerk wird inzwischen auch kräftig spekuliert, z.B. hier:

Chinese Stealth in Plain Sight: The Curious Emergence of the J-14 Fighter

...
One question of great interest to PLA watchers is what type of engine this J-14 prototype will use. It is widely speculated that China's domestic engine development programs remain inadequate for producing the wide array of aircraft being produced in China. The upgraded H-6 bombers use Russian D-30KP engines, JF-17 uses RD-93s, the J-10s use AL-31FNs, and until recently, the J-11s also relied on AL-31s. Thus heavy reliance on Russian engines is likely to continue. Unconfirmed Russian media reports and Jane's claimed that Russia provided 117S engines - the same used for its own PAK-FA fighter - for the current J-14 prototype, but this author is skeptical as to whether Russia would be willing to sell to China its best available engine, given its perception that China frequently reverse engineers Russian military technology. On the other hand, the use of indigenous WS-15 engines remains equally implausible, for it is unlikely that this relatively new and immature model would be ready for use on an experimental aircraft.

There is no still news about which engines are they using?
I read over the net and it seems unlinkely that they are 117S, so they could be russian engines developed specificallly for this plane? In that case i think we should already have information about it, on the other hand if they are chinese engines would be too good to be true (because these are clearly engines producing a lot of thrust, needed to power a so heavy fighter/bomber) ...

und ReneDad:

Since WS-10 has passed its design authetication for 5 years, it is reasonable that Chinese may have developed a derivative engine with T/W ratio of 8.5-9 from Taihang to power the fourth generation fighter.

It is impossible that the engines are a pair of WS-15. If a WS-10, which passed its design authentication 5 years ago, was still immature as some members here deeply believed in to fly with a third generation fighter J-11, who would believe WS-15, a engine even hasn't left its test bed, could be allowed to power a newly designed fourth generation fighter into sky?

As for 117s, I don't think Russian would offer it to help China developing her own fourth genertation fighters. Even if Russian would, I don't think they need to keep silence and give up the opportunity boasting how much China depends on Russian technology.
