it has been done in a couple of cases, problem is getting hold of DB engines in running order (and keeping up with the maintenance demands that come with it), plus the conversion can be a bit of a pain, cos you need not just an engine, but new cowlings, propeller + gov, spinner, supercharger, linkages... basically everything new from the firewall onwards.. quite an expensive game for a plane that wouldn't be genuine anyways. You should really be desperate to have an accurate looking Bf109!


Let's put it in this way: seeing/hearing a genuine DB or BMW engine is a rare, rare occurrence nowadays, and surely one to remember!
