One thing I have noticed missing from several photos.
You need to rubber mount...

thoughts?

can’t upload pic. Trying...

@Savington do you not sell the oil cooler kits anymore?

Or does someone have a PN for the correct sandwich plate with t-stat?

@doward Picked up some of TSE line.

Shoot me an email. I can get you hooked up.

Pegasus auto racing sells the Setrab 180 degree thermostat, part number SET-SPT76-20-180-22. That's what I used.

Any suggestions on sizing a Setrab Series 1? Perhaps a 34 or 44 row, oriented on it's side, is the route I want to go. Mostly a street car that sees monthly autocross with sporadic HPDE. I do plan to do more HPDE after install. Thoughts appreciated.

Vegas uses a 1 series Setrab. We find packaging is much easier having the I/O closer together. Anecdotally, more rows that are shorter tend to be more thermally efficient than fewer, longer rows and have less pressure drop.

We have switched to 1 series whenever the packaging allows it.

I used the same:

SET-125-7612 Setrab Series 1 Oil Cooler, 25 Row, M22 Ports

25 row, eh? What kind of ambients do you see? Has the 25 worked well for track work?

And I have benefited from that switch - thanks for the cheap 6 series!

I'd just note that for a mostly-street car, you're probably splitting hairs here unless you're generating a lot non-standard heat. The pressure and cooling differences between different arrangements are probably moot as long as you're not at one extreme or the other of rows vs length.

My $0.02.

You're probably right...I usually try my best to build in a little head room. Never know where a build will go!

As a champion over-thinker, I agree with building in headroom. The reality I've discovered though is that by the time you start needing that headroom, some other thing has come up which sends you in a different direction. Witness - "I love how reliable this car is on track, so let me completely replace the drivetrain because I'm tired of being passed down the straight by aggressive butterflies" -> well, I'm in there anyhow -> $$$.

I only had it on for a few events before i sold the car, but it made a huge difference. Flogging it hard for 20-25 min sessions in 90deg weather the oil temp peaked at 240f (1.8 na).

Just to be clear - this was a non-turbo application?

Yes, I said "na" but I see how that is confusing on a Miata forum :)

Not sure if Socals14 was talking about water thermostat or oil, but I am asking the oil thermostat question. From what I remember reading but now can't find is that it was to use the 205d thermostat for the Mocal sandwich plate. I can't find any vendor selling the Mocal with anything other than the 180f, also searched for the thermostats used in the Setrab and couldn't find an alternative. The only alternative would be the 200f Mishimoto unit. I'm not a fan of Mishimoto myself so I wanted to see what everyone else has been doing recently. Thanks

Try Bat-Inc for 205° Mocal things. https://www.batinc.net/

Another option that I don't see mentioned much is Improved Racing.
https://www.improvedracing.com/

I have parts from both companies, both are miles better than anything Mishimoto I've ever owned, seen, used or handled. IMO you are right in avoiding that particular brand.
