If I put a Skyline engine in my car, can I call my car a "GT-R"?

Yeah, I know it's a stupid question but I was just wondering. I don't have a skyline engine to spare but I'd like to know. Coz, It'd be pretty cool to have like a Mitsubishi Lancer Evolution GT-R. So, can I call my car a GT-R after putting in a skyline engine?
