Mishimoto Thermostat
 

Anyone this out?

Kenny's370z and I are looking to try it out.

If anyone has experience with these please share.

I think a lot of people do have experience with it
A lot of people say on a NA car it isn't going to help, AND if your coolant doesn't heat up enough your car will run extra rich and you'll get a CEL... I only know of one person who has installed this on a NA car and hasn't had a CEL...

Ill sell u mine for fifty bucks plus shipping. I bought it thinking my old one was the issue and it turned out to be something different had it in car long enough for it to warm up and then redrained it. Let me know.

what was your culprit if it wasnt the stat ?

i can tell you that the factory water gauge will reside on normal once my aftermarket temp gauge reaches around 148 so it may or may not throw a cel beings how the thermo starts opening up at 150.just depends on how cool it will allow the engine to run.if the water starts coming down below 148,then there is a good chance the cel will pop.

We used this in conjunction with water wetter and a higher pressure cap to help remedy some cooling issues observed on the 2011 NISMO we did. He had a road trip to Texas in which he didn't have a significant over heating issue, but he did say the temp gauge was a few dots above normal in slow traffic after have a little fun with the GReddy kit. Just those basic mods rectified everything.

Haven't had the chance to see how the heat works yet though!

Thanks,

The car was NA or FI?

If the car is NA but modded, it generally will run hotter since more power's being made, so the thermostat in that situation won't overdo it's duty right?

That might be true, but nothing near FI... I don't think your car will reach operating temps, or stay there with this thermostat on a NA car... Maybe if you turn the car on, wait one minute for the juices to start flowing then beat on it immediately?

As a side note; has anyone upgraded their radiator to the CSF one? I see Z1 Motorsports is offering one.

I would think that if you live somewhere that actually gets hot (Texas) and ran this one during the summer only you'd be good. If you DD your car though, probably a bad idea.

I plan on doing the CSF that has the condenser delete and seeing if I think I still need the stat, basically if I still see temp spikes under load while on the track/autox.

We have ran the Mishimoto tstat in quite a few of our customers' NA cars with no check engine lights.

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 have a 25ROW Oil cooler and an UpRev fan mod, I still can climb to 190-200 degrees when driving hard and/or being stuck in traffic.

Based on the above would that warrant the mishimoto and/or radiator?

I bet when it gets hot in the summer again my temps might fly higher, dunno.

I tried a mishimoto thermo in my mild mod'd Evo IX and it ran like crap. It would open up too soon and the car would stay in open loop keeping the temp way down and causing bad gas mileage (dropped from 18mpg to 12mpg). On the freeway, the car would warm up better, but once off the gas and cruizing, the temps would drop a lot.

I know it is not a 370, but should be the same principal.

:iagree: :tiphat:
