Don't pay any attention to Harris.
A key problem with the TAI KAAN's engine issue is that not just any alternative can be used. The aircraft design was specifically developed around the dimensions, weight, and performance characteristics of the General Electric F110 engine (or the future TEI TF-35000). This means that the choice of possible replacement engines is extremely limited.
The reality of modern fighter aircraft development is that the engine is not adapted to the aircraft – the aircraft is built around the engine.
This means that any significant difference in length, diameter, center of gravity, or thrust characteristic has a direct impact on the structure, cooling, weight distribution, and overall flight dynamics.
In this respect, the Chinese WS-10C/D is currently the only realistic alternative that comes close to replacing the F110 in terms of the key parameters – diameter, weight, engine suspension. Although the WS-10 is slightly longer than the F110, this could be compensated for structurally, for example by extending the fuselage in the engine area without completely changing the overall aerodynamic design.
All other engines – whether from Russia, Europe, or other countries of origin – either differ too greatly in terms of dimensions or cannot be integrated for technical or compatibility reasons without radically redesigning the entire aircraft concept.
This even applies to powerful engines such as the Eurojet EJ200 or the Saturn AL-41, which are either significantly more compact or more voluminous than the F110 and are therefore practically unsuitable as replacements in the KAAN program.
In addition, Pakistan has J-10 fighter jet with WS-10 C engines. I can't say for sure, but I'm certain that this option is being considered behind closed doors. For example, Turkish engineers may have analyzed the engine in advance to create the conditions for possible integration.
