The use in the Iranian drones, many of which have limited operating lives, means that anyone making duplicates doesn't have to work as hard to provide longevity. Getting the correct materials and surface treatments is not so critical if an engine needs to run for 10-100 hours vs 1000-2000 hours. On that basis the Iranians would have little difficulty making duplicates while keeping the cost down. The Turkish drones are likely for long-term loitering surveillance and would need much more durability - they may be operated 12-24 hours a day for months on end.
