Besides Driftmotion where can I get a thermostat. I don't see paying 20+ for a thermostat and its not even failsafe. Can I use one for a 2JZ?

Twenty bucks? I wouldn't even run a thermostat if I had to pay that much for it. Go cheap, it's really not even that important that you have one.............:rolleyes:

How many parts for the supra that you know of are 100% failsafe?

i think he means that if it fails it will fail open, instead of being able to fail close which could ruin the engine.

not an unreasonable desire at all...

with that said, i think it is better to get the toyota tstat (which driftmotion sells).

i was under the impression that the toyota thermostats do fail open?

Cya, is there a reason why you say they dont?

exactly.

I wasn't sure it did, it isnt advertised like most thermostats are. $20 bucks for a thermostat is still unreasonable even if it is a genuine toyota part. I was just looking for an alternative since after shipping it would be closer to thirty.

I thought he was trying to cheap out on something like most of us MKIII owners do from time to time. My bad.

2jz tstats are the same toyota one, i don't know how cheap yo uwant to get one for, but the cheaper it is, well you know where it goes

they SHOULD be cheap. they should be 3 dollars each for what goes in to them.

and even THAT is expensive.

but it is what it is unfortunately.

failsafe thermostats fail open and cause your car to run as if it does not have a thermostat. not allowing it to reach operating temperature. if you get a regular toyota thermostat it is not a failsafe. if it fails it fails in closed position and will overheat your engine. on thing i have learned from being a mechanic if you get a cheap failsafe it will stick open even when your car isnt overheating, which causes you to have to pull the thermostat out and reset it all the time.

They're used in other North American vehicles including (it's already been said), the MKIV.

I've never seen a Toyota thermostat fail closed.

No, Im not being cheap. Why should I spend more for the same results, THAT is crazy, especially when we as Americans already to work hard for the dollar as it is. I am not rich, im spending wisely. As stated Toyota T-Stats DO FAIL. Why would I spend more for something that I know WILL FAIL at some point in time. If you can give some sort of empirical result comparing T-Stats then and only then will I stop being "cheap". Its the same as paying (a very conservative) $300 for a used genuine toyota 1jz Map sensor (denso) with an FCD when I can get HKS three bar map sensor (Denso) for $175 dollar less, that equates to TWO three bar sensors. If that in your world constitutes as being cheap, then I have six genuine CYA 360cc fuel injectors with a rail ill sell ya for $50 per injector that bolt right up to the 1jz. Hell, no modifications required. Test fitted and proven. P.S. Ill throw the rail in for $20 just for you.

I was going to go purchase one from Advance Auto or Oriely (spell check). I've never had any problems with there T-Stats on any car i've had to work on.
