how hard would it be to drop a det into a 92 or so sentra (but not an se-r)? i am thinking of going this route as my g20 is quite costly and i can sell it fairly easily. what i want to do is pick up an old sentra with a good body and dropping that engine in there. some of my biggest concerns are 1) is it going to work? 2)will i be able to keep basic luxury items like ac? 3) will the electrics work-ie gauges?
