The J-xx or J-20 is nearly 80,000 pounds undoubdetly the heaviest and largest Stealth Fighter in terms of weight and size...
China currently lack the capability to make engines that can power this mammoth plane to operate like a normal fighter, The F-22 is 10,000 to 20,000 pounds lighter than the J-20.
F-22
Powerplant: 2 × Pratt & Whitney F119-PW-100 Pitch Thrust vectoring turbofans
Dry thrust: 23,500 lb[234] (104 kN) each
Thrust with afterburner: 35,000+ lb[2][234] (156+ kN) each
J-35 III
Powerplant: 1 × Pratt & Whitney F135 afterburning turbofan
Dry thrust: 28,000 lbf[270][N 10] (125 kN)
Thrust with afterburner: 43,000 lbf[270][271] (191 kN)
J-20 and the Wa-15 engines as of now are incapable of producing that much Thrust, atleast 150 kN...
RUSSIA's are STUCK at 147 kN for PAK Fa...
WS-15 is only around 90kn
China needs atleast 180 kN for J-20, (Goal: 18,350 kilograms (40,500 lb) / (180 kilonewtons (40,000 lbf)) with afterburner)
This will slow down the development and further push the introduction and induction phase further, possibly past 2018
