Thermostat - 91 Integra, 180F or 195F?

My Haynes manual specs a 195F Thermostat for 90-93 models, at the parts store and at the local Honda dealer they state 180F. Which is it? Any advantages to running one way or the other?
TIA

Oddly, the Haynes is correct (for once). The correct rating is 194F (90C).
Do NOT run a cooler thermostat than specified. You will experience slightly increased HC emissions and lower fuel mileage, along with accelerated engine wear. If your dealer is telling you 180F, you need to find a better dealer.
If you are having cooling problems, the absolute WRONG way to "fix" them is to install a cooler thermostat. The Integra's cooling system is very efficient, robust, and reliable. Unless neglected...
An OEM thermostat is less than $20 and is STRONGLY recommended over aftermarket.
