heh that's something I was wondering as well about the stock radiator (temporary)- my car is down at tophat right now being finished up and tuned and all, and I haven't bought my koyo yet- it's still on my stock radiator with a big 'ole fan.

I'm running the stock S14 auto radiator and it can only handle light city driving under 82F or so. Anything hotter and on an extended drive gets the motor pretty hot. I have a custom 2.25" Griffin 2-pass in the works. ($450 shipped)

Depends on your thermostat, but with the Z32 thermostat it runs at 83-84*C under normal operating conditions. If your radiator can't keep up, your temps will climb above that.
