thanks ! me too man,me too.

When you get it, do the hot water test to see the true opening temp. I am curious if they do start ot open at 150, or it is just claimed. Mine before started to open 5 degrees cooler than specs.

I'm still kinda leery of Mishimoto build quality. Personally, I'd go with the Infiniti thermostat. If the thermostat fails closed, you've got a serious problem on your hands. Maybe they're better than they were in the past, but I'm not going to be the guinea pig.

If you're tracking it, sure... And you're running a bottle, you have TOTALLY different needs

Sir, you are 100% correct

The temp is when it OPENS and it is fully open at about 20 degrees about the rated temp:
What does the thermostat do and what typically... — Yahoo! Autos

But I do wonder how quickly that spring loses it's... springiness??? If the maintenance manual suggests you change the radiator cap every 30k miles, why not the thermostat, it has has roughly the same design, no?

But a 150 degree thermostat still feels low. I believe the car "wants" to be at 180... And has anyone ACTUALLY confirmed the engine pulling timing once the water temp reaches 190, I have seen a lot of recent speculation because "a guy at the dealershit told me"

It would seem REALLY stupid to me that Nissan would put a 180 degree thermostat only for the car to start slowing itself down 10 degrees later...

And different front bumper for better cooling FTW! Not enough air reaches anything in front of out cars

I'll be the guinea pig, I think I'll buy it and install it Friday, and I'll keep you guys updated

What bumper do you suggest?

As for the CSF radiators, they are great products but probably overkill for a NA car. We use these radiators on our TT applications.

I am seeing huge power drops because of coolant temp (10 degrees = 4 timing = 15-20hp on my car) and spikes to ~230 during AutoX events.

I think the CSF radiator is exactly what I need to get that under control... Unless you have other ideas? I'm definitely open to suggestions!

I'm planning on doing that in December, I'll report back when it is done.

If you are tracking the car, then I would definitely recommend the CSF radiator and the t-stat. Whenever you are ready to pull the trigger, we can get them for you since we are direct with CSF.

Just tossing this in there....

You can run a 350Z VQ35DE Thermostat on a 370Z as well. There are many more options for the older 350Z thermostats than for the 370Z's VQ37VHR engine. The only difference is that you will have to remove the Pipe fitting from the thermostat and install a plug.

I made a batch of Low Temp 350Z thermostats for a 370Z owner by knocking out the pipe and tapping it for a NPT pipe plug. Sealed perfect with no leaks. Some of the 350Z thermostats open up slightly lower. Mishimotor 350Z themostats open up at 62° vs. the 370Z model at 66°.

But even TX's 100+ degrees isn't enough to warrant this thermostat (again, maybe if you're Sh0velman who tracks the crap out of his car, then yeah)

If you want a little lower without risking a CEL or running rich with crappy timing, buy a OEM Infiniti 2008 G37 thermostat

i decided against the mishimoto and went with this stat.glad i did as i dont track the car and my temp stays around 170.i endorse this stat !

I'm gonna go with the CSFradiator, I think that will work better for all around cooling.

You gotta get the oil cooler kenny. just gotta

Not to thread jack, but would you recommend the CSFradiator for mild track? Mainly use my car on the road as a DD and spirited driving

binary0x01 · 11-04-2012, 01:14 AM

I am getting it because I'm going to track the car and because I want to keep it for a while so getting a quality radiator is a good investment.

Juice14 · 05-09-2013, 03:28 PM

So any updates on people who have installed this?

I live in the caribeean and Its always around 85 degrees here. maybe 70 degrees at night in December. I track the car probably once every 2 months. I have a 34 row cooler and the oil temp still gets up to 240 easily.

So i checked my car's water temp and it was 210 just driving some what spirited.

It's funny you reopened this thread because I ordered one today from z1 but canceled it because Iam afraid it might be too run too cool... Has anyone tried this yet with FI?
