ok i can get acouple thermostats from work ...i think the stock thermo opens up at like 195....i was looking into getting one that opens up sooner i have found acouple, 160,170,180, and 190 i was gonna go with the 160 but i figured that would be to low of a temp for winter....what is the optimal range for the rotary engine?????????

also what all do you have to do for the 4 piston swap.....do you have to swap over hubs, or just brackets, calipers, and rotors????

 

Is the car 4- or 5-lug?

As for the thermostat- it's not that expensive! You're MUCH better off using one that's made to OEM specifications.

 

The 180 seems to me to be the best compromise between cooling and unfreezing your face in a timely fashion during th cold months. I have the 180 in my car and I like it. Search for a writeup on 4-5 lug conversion. Its be covered many times. You will need 5 lug hubs, calipers, rotors...do a search. Everything bolts right on once you find all the parts.

 

A low temp thermostat won't help with cooling if that's what you're trying to fix. If it's not having problems with cooling then it'll just make it run at sub optimal temps which are bad for the engine and will lead to things like increased wear and tear and lower fuel milage.

 

Unless you work at a Mazda dealership, NO.

steer clear of ANY aftermarket T-stats.

OEM ONLY. And only the optimum operating temp of the engine unless you live in EXTREME climates where changing this would be necessary.
