I recall someone was having a hard time finding a 170 degree thermostat for their car, but I don't remember who it was. I was buying a stock one for my Z along with some parts for my girlfriend's car this week and asked if they had any other temperatures besides the stock 180 degrees F. Indeed, they do list and carry a 170 degree version... so in case anybody was wondering NAPA does carry it.

ugh, any colder than 170 is pushing it, imo.Attached FilesBLOZ UP.com

im running a 190* thermostat. i put tht enew one in last winter. it was below 0* for 3 weeks. i don't like to be cold.
i bet if i switched out in the summer for a 160* one my car would run a little better.Another one dead: 1985 2+2 GLL, stripped going to the recycler!!! doing my part to stop global warming!
the sierra club is gay!!!

The ECU will enrich the mixture if the engine stays cooler like that ( I think NisMo is 160 ) and it will hurt fuel economy and (at least in theory) engine life very slightly. I've always used stock temperature for best econ and ease of tuning... I've always thought the enrichment from running cooler would simply throw off my logged AFR's in relevance to the map. Even though looking on the temp enrichment variables, it's a very small difference. Anybody care to add?
Either way, the 5hp mods are the ones I tend to skip right over. On a side note... I seriously can't believe it when people list things like synthetic oil or fuzzy mirror-mounted dice in their modification list.

I don't think a cooler engine temp than 160-170 is going to gain you much of anything. If it did, then you'd see more race cars with elaborage temp controls to get it down there. I'm certainly not an expert, but I have not seen anything indicating as such.
And everyone but vatozone carries them around here. I had to special order a 180 a few years ago for the winter.

the t-stat doesn't in any way raise your cooling system's thermal capacity, what it can do is help delay the rise in extreme temperature buildup, and if the heating is sporadic rather than constant, it could seem like it is cooling the engine more effectively
but in the case of jason's little story, 20min at wot and such, 160 wouldn't make a difference over the 180 even
a bigger/better radiator is still the only true way to cool more effectively at constant load
it is possible colder head surfaces will resist carbonizing a bit in the beginning but once it's all gunked up that stuff acts as an insulator so it won't help in the long term

And brass and copper OEM radiators are better than aluminum aftermarket ones as far as heat dissapation goes, all else being the same.BLOZ UP.com

I agree though, the OE cooling system is more than adequate; even on my car with an IC blocking 80% of the flow through the radiator.
