So is a 180 Thermostat worth doing?
Some say if the car doesn't reach a certain temp (192) the car won't run like it should.
However,
Cooler engine, cooler air = better right?
Able to advance timing a bit more too?

180* 'Stat

With the later model cars lowering the 'stat temp probably won't be of any benefit AND the hotter 'stat helps keep your engine from building up sludge. I'd stay with stock-but that's just me!

I agree. Leave the 192 in and work on getting colder air into the intake. Everything is programed for the 192 and anything less then that will effect overall performance.

I'd leave the stock thermostat in too.

IMO, its not worth the 12 degree difference.

Keep the stock stat.

I installed a 160 degree thermostat in my car and reprogrammed the fans to come on at 160 degrees rather than 208 and saw no difference in engine temperature in the summer because the radiator is inadequate to take enough heat out to maintain that temperature. When the weather cooled off, it was able to maintain the temp at 160 and I saw no noticible difference in performance and was able to pass the sniffer test when I had to get smogged. For cars with carburetors it helps because the engine runs richer, but for our cars it is probably a waste of time. You might be able to advance the timing a few degrees, but it is a lot of hassle for the potential gain.
