There were V6 lancers sold in Japan (I don't know where in the world you are, but the JDM Lancer is the US Mirage, the US Lancer is the JDM Cedia), your best bet would be to get a JDM V6 Lancer front cut. That way you will get the engine mounts etc that should fit your lancer a lot better than the FTO set up.

However, note, depending on where in the world you are the RHD and LHD chassis differed quite considerably year to year, and the job may be either very simple, or impossibly expensive.
