So would you say this is worth the 100 bucks or only for the extreme performance minded individual?

While I think the Nismo thermostat is a good choice for me, I would say for most people the stock 350Z is the smarter choice. Its not quite as good as the Nismo one, but it's better than the stock Frontier one, and it's about $100 cheaper.So would you say this is worth the 100 bucks or only for the extreme performance minded individual?

you obviously dont know the points of changing out thermostatsWhy do you say either is better than the stock Frontier? You have no data?
And the stock one costs $0 extra.
I don't have actual datalogs no. I do know that the stock Frontier thermostat runs hotter than the stock 350Z one. Some Superchips/Hypertech owners can say better than me, but I think stock we are in the 185 range. Can some of you guys verify where you run?Why do you say either is better than the stock Frontier?

True, running cooler does allow you to running more advanced timing. But engines running hot often get heat soaked in normal traffic situations. Heat soaked engines will produce less power. Engines like cool temperatures for better performance. I know I've had heat soak problems at the track before just waiting in line for my turn. Run a lot of back to back runs and your times usually get worse, usually to your engine getting heat soaked. I've also seen many trucks getting tuned(me, shiner, thillskier) that the heat was hurting their power. Sitting on the dyno, most of us were getting close to 200F. With no other changes done, after letting the engines cool just a little, maybe to 190F, often increased the horsepower readings about 5whp. Maybe not much, but the difference of a stock frontier thermostat sitting in traffic getting maybe 195F or so versus a cooler running frontier with a Nismo thermostat sitting at a highest observed temp at 176F should make a measurable horsepower difference. Might be only 5 horsepower, but I'll take what ever easy gains I can get.DOsen't the increase in HP only come with the ability to be able to advance the timing, though (due to it running cooler and less chane of detonation)?
It's not that it technically gives you horsepower, it's just that a cooler running engine via a cooler thermostat(read Nismo or even stock 350Z) allows your engine to perform at its best at all times. If your stock frontier thermostat allows your engine to get hotter than optimum for performance, and in most cases they do, than the cooler thermostat will give you a horsepower increase.If I am going to replace the thermostat in my 2006 Nismo what year does the 350z thermostat need to be and how much do they cost? I'm not familiar with the z's.
And you are saying that in some situations there should be an increase in power even before I do anything else like advance the timing? Maybe at the small expense of emissions and a slight loss in fuel economy? (probably the reasons it doesn't come this way stock)
That is correct. I've now have had the stock frontier, stock 350Z, and currently the Nismo 350Z thermostat. They are all mechanically the same except the temperature that they operate at. No issues with any. And like I noted earlier, unless you are going pretty serious with your mods, the stock 350Z is a great choice mainly because of its price. The Nismo one is the best, but at $110-$150 for it vs $20-30 for a 350Z thermostat, for most its overpriced for the extra 6-8 degrees it keeps you cooler over a stock 350Z thermostat. But for people going beyond the basic bolt-ons, like me, the Nismo one is a good choice.Ok, I think I got it. The frontier and the z thermostats are the same except for the temp rating and there are no compatibility issues to worry about.
No colin, on the frontier, 350Z, and the nismo thermostats, they all come as a complete assembly-housing & thermostat-as one piece. They are all totally interchangeable. It's just that the frontier and stock 350Z one is much cheaper.just a quick question, if i got it right to do the 350z tstat you have to buy the housing and all that too, well why not just get this nismo tstat from the nismo shop thats direct bolt in for $100 bucks The Nismo Shop : West Covina Nissan : Nismo Thermostat 1998-2008 or would this one not give the cooling you wanted
Yes they are very expensive for a thermostat and thats why I bought the 350Z one last year for about $25. But with my recent cam install I figured it was as good a time as ever if I wanted to get the best cooling for my truck, so I bit the bullet and bought the pricey Nismo one.OMG, $110-$150 for thermostat!
Last time I bought one was for an '81 Ram and it couldn't have been more than $2, but if it does yield 5 HP or so it's worth it when you consider a CAI (etc.) cost 2X-3X as much and maybe gives 5-7 HP.
Now about heat soak. I don't see an advantage there. No matter what thermostat you have it will be wide open when you are in bumper-to-bumper traffic, A/C blasting and it's a million degrees out. I can see it beneficial in normal driving though (moving).
That was a great write-up Colton. You rgreat luck with it is the main reason I decided to fork out the extra bucks for the Nismo thermostat insteading of hanging on to my 350Z thermostat.
I don't doubt that some are different. I also understand some are rated at different temperatures too. Thats why its a good idea to pick it up at a local dealer so you can see it before you by it. Also I know the nismo thermostat came with a gasket. I think they stock 350Z did too, but I"m not sure.Just to clarify, in another thread it was discovered that there are some z Tstats that don't fit. Something about it missing the heater tube part. I know for sure thou, the 07 Z tstat works.
Also, if you are swapping Tstats, you might as well swap the gasket to ensure it doesn't leak.
got ya thanks for clearing that upNo colin, on the frontier, 350Z, and the nismo thermostats, they all come as a complete assembly-housing & thermostat-as one piece. They are all totally interchangeable. It's just that the frontier and stock 350Z one is much cheaper..
