i got a comp belt drive on my motor. Only thing i dont like about it is the belt is so much wider than the jesel. They have you put spacers on your water pump. (min 1/4" spacer) other than that its a nice piece. I havent had any problems at all with it. I broke a crank and it knocked every valve and locked up the cam shaft. Broke the belt but nothing else got damaged belt drive wise.
