There is a possibility of an engine change in the Block 3 with an uprated WS-13 variant called the IPE (posted in chini mil thread.) The penultimate Blunder block is supposed to be powered by the WS-19 slated for the porkis' AZM 5th Gen (FC-31.)
I think i read somewhere that PAF has decided to stick with the Russian engine. They know, they cannot depend on a unproven engine on a SE fighter, which will become the backbone of their fleet.
The WS13 is listed at 90KN, that is 6KN more than the F404 on LCA MK1! It will still not have enough power for a 1200 TRM radar. If it is claimed to be the "air cooled" version, then it indicates two things: lack of power, that's why air cooled and if 1200 TRM is true, then excess TRM to maintain higher failure rates, compared to a liquid cooled version.
Once our AESA FCR, SFDR, XRSAM, MWF starts rolling, Chinese wouldn't be able to provide the tech equivalence, as they will need to sell their top line kit to allow Pak to compete with us.
