Even if it bolts in, you will have trouble with the engine electronics, ECM and other items. The 2012 is a different generation which means major changes from the 2006 model. Any time you are installing a different size engine, there will be all kinds of problems. Starting with the motor mounts, exhaust system, Engine Control module, wiring harness, emissions, transmission, etc, etc, etc. This will be an expensive project.
