I have a 2013 Dart that I plan to do a 5.7 Hemi swap with. I have a few questions. The donor car is a 07 Dodge Magnum. First question is, with the understanding that they are both unibody cars, could I take the whole front subframe from the Magnum, and narrow it down enough to exchange with the stock Dart subframe, essentially transferring the engine mounts and everything from the Magnum, to the Dart, then just integrating the original suspension set up into it? Second question, once the engine is installed, would it be best to tuck the Dart's stock ecu back somewhere so all of the factory options still function (back up camera, lights, radio, tpms system, and so forth), and put in a stand alone fuel management and ignition system in to control the engine? Or is there an easier option? Third question is, how would I wire in the factory gauge cluster to the engine, (RPM, speedometer, Temperature, ect.)? Any info on what problems I might run into on the build would be appreciated.
