With an afterburner? Color me skeptical.
I think this is more in line with the kind of news they routinely release for domestic consumption.

ALCON,

IMHO (per a visual inspection/comparison), the engine Iran displayed is a J85-GE-21 w/ afterburner.

By the contents of the videos released as well, at the very least it looks like IAIO has the ability to perform a complete/total overhaul of the engine and could very well be able to manufacture it.

As to it's use in the Kowsar-88, it's interesting to note that Iran's previous jet-powered trainer concepts (Dorna/Tazarve family) all used the older J85-GE-13 w/o afterburners (which produces ~2850lbs of thrust).

Perhaps then, it was decided that starting with the more powerful/sophisticated -21 variant was a better plan for future projects. Such a plan would logically start with a reverse-engineered -21 variant "as is" aka w/afterburner and THEN built a non-afterburning variant (which should be a simple task to my understanding).

On a separate note, it should be noted that B.T. outright dismissed suggestions that the Kowsar-88 concept was a AT-3 like design a few years ago. At the time, he claimed the Kowsar-88 was another name for a F-5F related project. Now, he suddenly "discovers" the Kowsar is instead a twin-engine design which looks quite similar to Taiwan's AT-3.

Attached is an image of a sub-scale drone/model Iran showed off a few years ago when the first articles about the Kowsar-88 were published and what do ya know...

It is possible they've managed to improve the J-85 slightly. "Indigenous" could however simply mean "made in Iran".

Owj is clone J85-GE-21 which itself was heavily redesigned J85 in order to improve performance of F-5 with F-5E/F.

Kowsar-88 is now known as Yasin, at a glance similar to Taiwanese AT-3 advanced trainer jet.
