thank you for the info.
My fans are hooked up directly @ the moment and they help alot when i cruise around(88*- 90*) but the moment i step on the highway my temps go up to 96* and even then, when i slow down and cruise on the highway it still remains @ 96*.
I have a koyo radiator, FMIC and i'm also single turbo(400hp) and also have a apexi AST and i also use texaco coolant. I was wondering if i remove the thermo, if it would help out a bit. thank you

Dale - is this issue still valid ? I noticed Mazdatrix took down their page on issues with the OE/Mazda thermostat.
Also, could you jump to this thread and comment:

Yeah I'd like to know where we stand on this nowadays.
I'm looking to replace my thermostat around Christmas 2016 as preventative maintenance (when I'm scheduled to do my next coolant flush) so I'm researching thermostats now.
I believe my current thermostat (which is working fine) is the original 1992 thermostat still in there.
Mazda/Billion/Sard/Stant, whats the current consensus?

the OE one is an NTC, which isn't too hard to find.
no affiliation except that these guys use our catalog, and maybe our warehouse

I just received a 89~95 Tstat from rx7.com and it doesn't have the rubber like dales dose . so those are OEM the one, i got is aftermarket?

i tested in boiling water and it dosent crack open untill like 183F, and very slowly opens up. at 180F it looks to still be shut . and it opens slowly .didnt get hot enough to see it fully open, and i used a crappy walmart meat thermometer

I recently had a year old Mazda thermostat fail on me. Luckily I caught it before the motor overheated. I think the problem is a lof of these parts are new old stock, so they could have been sitting on a shelf or in some warehouse for 2 decades.
A front mount in itself will not cause an rx7 to overheat. I set up plenty of cars that see track time with no issues with a front mount. The key is a robust radiator, and adequate ducting to it. That being said, a v mount is still the best option.
