PSA do not use a non oem or racing application thermostat in a 4g63
As the title States steer clear of your local (parts store) for a thermostat if you care about your engine.
I thought replacing my thermostat with a new one from a local parts store was a good idea at the time (gasket was bad) it was leaking a little what I didn't realize is that the brand new thermostat I got from autozone never actually opened. This would lead to overheating, fans not working, CEL code throwing for insufficient operating temp.
Take my advice it's been said before, but if you care about your engine get the thermostat from mitsubishi or a reputable racing parts company (mishimoto comes to mind)
The part number for evo7 and evo9 looks to be the same as the DSM 2g (pay attention to temp operation) looking at the evo9 one oem opens at 176f and full open by 199f those are pretty good numbers.
If people have specs and real world experience with some different thermostats I'd like to know how it looks on temps.
230f is too hot for our DD dsm's they like to run about 180 however I have found if your thermostat starts opening at 180 it's not going to keep it real close to 180 it will run hotter.
