Just out of curiosity how many of you guys have changed your thermostats in your RX7s? If you have changed them what brand and type thermostat did you use? Also, how warm are your cars running, approximate where the temp needle sits when at operating temperture. Also, how stable does your temp stay say in town in stop and go driving vs on the highway?

 

on my old car it was 165 F in city and 180 in freeway. I never changed the thermostat tho.

 

Everyone says to stick with the Mazda OEM thermostats; 86-88's run about 1/4 to 1/3 up the temp gage...I think I've heard the S5 guys say theirs run at about 1/3 to 1/2 way mark
