Its not a technology issue. Its just that by now the J-8B airframes are getting old. If you upgrade the J-8Bs, you're putting money on an airframe with already limited flight hour life. Its a waste of money. You should just retire the old airframe and build new fighters.
Well the J-8D's redesigned, heavier airframe I assume would be a factor in having a longer flight hour life compared to the not much older J-8Bs.
Another question (sorry!
