High Performance Thermostat by Mishimoto
 

I wanted to know if anybody has installed this product on their vehicle? Was the install easy? Any and all thoughts on the product would be great.

Bump!! Come on guys

Hey, I have no installed it, but I did look at it for a while....If I remember correctly that activates at like 140 degrees? I thought it might be a little too cold for a daily driven car to warm up properly. Just 2c...

Ya that's what I was wondering if this was going to be overkill. Just looking at ways to cool the car down but not overdo it.

It operates at 150 degrees (66 c) . I also would like to know how it perform.
The Nissan thermostat that made for Middle East , it operates at 170 degrees (76.5 c)
Just FYI.

well, that was such a great stuff specially for racing. my 370z has been modified last week and just and update...im proud to say this thermostat really works especially in warming the engine.

Mine is being installed right now. Stillen oil cooler (25 row) next week. Oil runs a tad hot on track days so going for some mods to keep temps cooler.

Install is a breeze if your already working on the cooling system.

I installed mine and it popped the engine service soon light a couple days later, reset it am waiting to see if it pops again.

I've heard nothing good about them. I have seen at least one that fell apart into pieces

Joe- Want to make a better alternative in the 120-150$ range?

I saw this happen 2 weeks ago to a STI, lol, took mine out, car runs the same, temps are fine.

The Nissan OEM thermostat kick in at 170 degrees?

180...at least for a 2009+ G.

I changed mine to the one from a 2008 G which is 170deg when I swapped in the CSF radiator.

Nope. Not unless you're in the middle east. It's 180.

And the Mishimoto thermostat is a good way to blow up your motor. If you've got to buy their rotting garbage masquerading as car parts, at the very least don't buy parts that will make your car go boom when they fail like a thermostat or anything related to the oiling system. Those assclowns could **** up a bowling ball.

Mishimoto thermostat bashers
 

I have had Mishimoto thermostats in 2 Z's - a 2007 and a 2011 both of which were/are raced frequently. No issues. If/when I change up to a cooler radiator I may blow the $ on a Nismo part but until then the Mishimoto works just fine. And for any bashers of the part - how about a pointer to a real URL for a problem not just anecdotal comments??? IE if the problem happened to you then that is evidence, if you heard about it somewhere that is not evidence...

The OEM Nissan thermostat is cheaper than Mishimoto. As far as experience, why not ask O&G how his looked when he took it out? Or his buddy, who lost a motor when his failed shut? Or the guy here who dumped all his oil on the road because their sandwich plate failed?

Ill post the pics up in here when I get to work. I feel sorry for anyone running mishimoto parts! Go China :/

Got any pics of the pile of their crap at Jtran's? :rofl2:

I don't have any sympathy for anyone who has a catastrophic failure of their parts at this point. There's plenty of end user feedback that would tell most rational individuals to stay away. Using their parts now is simply a complete failure to do any research or being too cheap.

Maybe they come from the same factory as COSMOs manifold:rofl2:

Even better is their customer service. When one member here had a major failure of their sandwich plate that could have taken out his motor, they mailed him a new O-ring. :rofl2: Weeks after they claimed to have sent it out. And then their VP of Douchebaggery came in and likened the whole thing to the Challenger disaster.

Here we go. Found it. Anyone who can read this and still use their products is mentally defective.

I will never let anyone I care about use Mishimoto products after seeing their thermostat fail on a good friends motor, causing it to blow. He sold the car and retired from the modding scene. I also had their thermostat fail, but I was more fortunate and didn't loose the motor.
Mishimoto is on the left w/ 4k miles on it, Stock unit is on right w/ 6k miles on it........... as you can see the O-ring seal is already gone on the mishimoto while the stock unit looks fine. QUALITY matters.

Forums are here to inform, throw some truth at the readers!

I could build a 2 story house for a homeless man out of all the Mishimoto failed radiators we've had lying around here. We gave them all to this old scrap guy who comes by twice a week. He puts them to good use!

I'm from Houston also guys, should I add an oil cooler kit? I heard it can blow the motor if the hose break?

Yes to both. The odds of breaking a hose is pretty low, though.

Just make sure you order the Z1 kit or maybe the Stillen. If you put Mishimoto the hose will break :), but you can send the broken hose to me and I can give it to the scrap guy, he would appreciate it!

We actually just had a G37 customer come in who lost all his oil due to his Mishimoto core cracking, luckily he didn't loose the motor!

thanks for the info guys!!! How about during winter time...will it be a overkill ? How will the engine warm up?

Sorry I'm new to all this mod stuff.

It'll be fine. Just drive easy until it's up to temp. You want one with a thermostat in the sandwich plate.

Make sure it has a thermostat

I can't use the thermostat thats on the car already?

No. Thats for coolant.

You already have a thermostatic oil sandwich plate?

ic, thanks!

nope.

How hard it is to install myself?

Very DIYable. Take off the bumper, drain the oil, put the sandwich plate on, mount the core, run the lines and refill with oil.

What he said

Does anybody know if there is another aftermarket Thermostat different from Mishimoto's?

The nismo de if you plug the extra coolant pipe, the 08 g37 lower temp one, or the de ones are all different temps to use a de one you just have to plug the second nipple on the de thermostat. It is double acting thermostat so it is a bitch to make hence no one makes one. when it gets hot it both opens the draw hose and closes the bypass tube at the same time.
