I just recently got a 1996 Integra GS-R a little over a month ago. I was wondering when I should change the timing belt and water pump? I hear that it should be changed every 90,000miles (144,000kms) I'm not at 220,000kms so I'm not sure if I need to change or not. I read somewhere I should change it at 70,000 miles (120,000kms) if I'm driving it under heavy conditions. So should I be changing it at 288,000kms or 240,000kms? And if I do change the belt I should change the water pump as well?
