the only thing to mid mount in an NX and be respectable would be an SR20DET. fully built, caged ( because it would probably be flipped at some point of shennanigans), and the cage triangulated into the front suspension. I also say put a mini fridge or pony keg-erator in the engine bay to balance it out and call it a day. rear engined drunk drifting NX madness. Keep in mind, this is all on closed roads, or the hell with it, jack it up and put rally tires on it. Go into a cornfield and have fun.
