If you're specifically looking for a Tamil dubbed version of Aashiqui 2, I suggest checking with popular streaming platforms or Tamil movie streaming websites. However, I couldn't find any information on Aashiqui 2 being officially dubbed in Tamil.

Aashiqui 2 is a 2013 Indian romantic drama film directed by Mohit Suri and produced by Mukesh Ambani and Sanjay Dutt. The movie stars Aditya Roy Kapur and Shraddha Kapoor in lead roles. It's a romantic thriller that explores the dark side of love and fame.

Regarding Isaimini, it's a popular Tamil movie streaming website. However, I couldn't find any information on Aashiqui 2 being available for download on Isaimini.
