So i have the stock dc integra radiator in my car and i have the stock fan set up for it. I really don't want to spend 500 dollars on a radiator and fan. So i was looking at oe replacement radiators. I was wondering with the ep3 and the rsx radiators if i should go with one of them or another integra rad. Do the rsx and ep3 rads just drop in or do i need to move the lower mounts or anything thanks for the help.
