The J-20 was to use a engine built for the J-20, but hey had a problem, so in their rush to production they used older engines that compromised not only the aircrafts stealth ability, but cost them its super cruise capability

The older engine, the WS-10B, is basically the same kind used in the J-11 and J-10 fighters in 1998 and 2002.
Without the new engines, the J-20 can't supercruise, or fly faster than the speed of sound without igniting its afterburners, like the US's F-22 and F-35 can.
"Afterburners do make any fighter much easier to detect, track, and target using Infrared and Electro-Optical systems at closer ranges when in use," Justin Bronk, a combat-aviation expert at the Royal United Services Institute, told Business Insider.
