I am wondering if 210-214 is too hot?

 

Nope. 230+ is

 

Coo, so i am pretty safe around 214-215. Thats hottest it ever got.

 

I guess you're safe. I wouldn't consider my cooling system good by any means if I stayed above 200.

What is your cooling setup?

 

I have a stock radiator, 180 dedgree t-stat, small eBay intervooler, 50/50 mix and I m pretty sure I got a bottle of water wetter in there. I don't have the stock air splitter installed or the engine plastic guard.

 

So you've done everything wrong you're saying.

Install the stock undertray, install a 160* thermostat, drain, flush, clean, flush, fill, drain, flush, clean, and fill your new all aluminum $160 radiator with more like 40/60 coolant/distilled water, and install a reroute. Congrats, you've spent $200 to solve 99% of your over heating issues.

 

Well, I don't have the money or time for a reroute right now. The best I can do right now is a figure out how to fit the undertray back on.

 

The T-Stat is unnecessary in this weather climate. I don't have the under-tray on either, but I have a mishimoto 55mm radiator. That's all I've done, no unnecessary reroutes or any of that other mess, and I never peak above 205 under 17psi boost on a 94º day (so far).

Edit- Oh and that's with generic 50-50 mix coolant as well..

 

Most of what Curly mentioned is either free, or stupid cheap, so start punching down the list.

Read up on my reroute, I think I might have spent $40 on it, and some of it was for a spacer I never used. The rear Gates hose that was kinda expensive could have been replaced with a cheap piece of straight hose had I bought the metal mid pipe that already had a 90* bend in it.

That and some ducting/undertray action will make the stock radiator sufficient for street driving until you can buy an aluminum one. These are also upgrades you can do a step at a time, each of which will show marked improvement until you've got an ideal setup.

 

whoa! whoa! whoa! "unnecessary reroutes or any of that other mess"? 'the **** bro? why you talkin ****? just because you run your engine rich and under-timed doesn't mean everyone else's vagina bleeds in the wind the same way.

the reroute is not a modification, but a return to the proper design that has been incorrectly configured for uneven cylinder cooling. you can say "i'm too much of a bitch to want to do it" but don't speak negatively of the coolant reroute.

edit- nice! I got some red font! my dialect is a mixture of satire, insomnia, and ridiculousness. I hope no one other than the WARNINGBOT was offended...

 

No undertray, 30 dollar ebay rad and 200* all day. 50/50 aswell.

 

^ Ooh, another turbo miata in the TCs, where you located?
