I don't think the oil-to-water cooler was sold as an option, but I have seen late model B18C's that do not have it. :thinking:
If you're concerned about oil temps, I would look into buying a sandwich adapter, AN hoses and an external cooling radiator.
Call me a skeptical bastard, but I distrust oil-to-water cooling setups after seeing the aftermath of one leaking internally. It wasn't on a Honda motor, but main bearing failure and a blown head gasket were just the start of the problems.
