I need to find out what kind of tranny case will bolt up to a 2.5 RS. Is the 5mt for the 2.5 the only one that will bolt up? I am going to be using the case (just the bell housing) to make a mounting plate to put my engine on the dyno at work. I need to know if the 2.2 or 1.8 tranny has the same bell housing with the same bolt pattern, so I can get this beast on the dyno. Also, does anyone know where I can find one?(cheap) Please help!!!!!
