I sure will. I didn't get a chance to take the Miata to track but I might be able to drive my buddy's prepped Miata for a few sessions ( he bought the same model year car ). I really liked the Miata but couldn't really fit in comfortably and lack of back seats for the kids ..since I am a big guy so wanted to try another light car so hopefully BRZ will do the task..

This is the same track with the EVO X GSR (stage 2 bolt-ons, tune etc) , it is a great track

It is an oil heater. The primary purpose is to get the oil up to temp faster in cold climates; the turbo is oil cooled, and needs proper lubrication.

I believe the ECU starts pulling your power above 240F. Am on mobile though, so can't double-check.

It functions as both a heater (arguably just as important!) and a coolor - and having it is better than having nothing. I don't think you can disagree with that, Mike.

Absolutely agree!

And the car comes with nothing stock...

In any case, I'd prefer the "OEM" cooler in-line with an air to oil cooler if that makes sense. The problem with coolers is that they are too efficient (see: winter) and this engine already has a cold oil issue as well as a hot oil issue - either a higher temp thermostat, a piece of cardboard, or the two cooler solution I speak of is what I'd be interested in.

Or this cooler with a more efficient radiator would also work and be less complex while still providing both adequate cooling and heating.

That's why a thermostatic plate is supplied with the Jackson Racing oil cooler; you won't overcool your oil

This is why I like the robispec style radiator/oil cooler. It's self regulating, doesn't require running hoses to the front of the radiator where they could be damaged by FOD, is efficient enough to cool both fluids, and should be a cheaper solution than a proper oil cooler and upgraded radiator.

I just don't know if I'll need one in my climate.

Just an FYI -- the Robispec is *not* self regulating.

OEM sandwich coolers are inside the thermostatic loop (and therefore temperature regulated). The Robispec is *out*side the loop. It's really designed for track. You could, I expect, use it with thermostatic sandwich adapter, but that's not what it comes with (at least last I looked).

By thermostat I meant thermostatic sandwich plate - what temp does it start bypassing?

I believe 185 is when it trickles open, but don't quote me.

It is, in the sense that it's regulated by the coolant...

You're correct. It's 185F. I remember asking over expresso

[OrbitalEllipses]

Yeah, 185* is the same as the Mocal - will still be too cold in the winter.
