Is there any thermostatic sandwich plate worth considering? The Mocal one is extra-baller, but a bit rich for my blood.
I was thinking something more like the $30 derale thermostatic adapter

GM version is OK, although I vastly prefer the BSPP/Dowty seal setup that Mocal uses over NPT. I also don't see a GM-style 1/2" adapter in the proper M20 thread.
IMO, the added cost is worth it. Mocal is what OEMs use when they need a sandwich plate adapter. It's $122 including the adapters and Dowty seals, so we're not talking about a several hundred dollar difference.
Can you please be more specific about this? What does the warmer accomplish by being in place? A lot of people have 1.8+ swapped into their 90-93. As I'm re-using my 1.6 oil cooler I'm sure others are too. I.E. I don't have the warmer . I do have a fancy glow shift plate.
edit: Correction, 205*F sandwich adapters are in such low demand that Mocal does not stock them, so I can't get them without a large pre-order.

So n/a car with a/c it's preferable to mount the oil cooler in FRONT of the radiator? How come I saw Emilio put the oil cooler in the engine compartment BEHIND the radiator in his OGK car?
What about mounting the oil cooler to the steering rack like FLyin' Miata? Let's talk about oil cooler durability in the event of an off-course excursion.

I believe due to the configuration of that particular motor, there were troubles getting it UP to temprature. Notice how half the radiator is blocked off? That is not any sort of standard configuration, do not copy it. That picture has really fucked up peoples brains.

I'm not saying they're right or wrong, but I'd be interested in opinions on their setup. Motoiq has their oil cooler mounted behind the radiator as well, but in a much different fashion.

I saw north of 270 degrees on mountain roads in 80 degree ambient, driving spireted but certainly nothing close to track driving. (Same car)
My '99 had the same oil temp sender location ^ and similar oil temps before I put the blower back on. With the charger on, I back off when I see 280. I need an oil cooler soooon.
I could easily see how a stock miata on a track on a warm day would have dangerous high oil temps.

180*F is fine. Running a 180*F Mocal adapter, I used to see warmed-up street temps in the 190-200*F range. You want to get the oil up to ~180*F, but it's less about viscosity and more about heating off the fuel and water that inevitably makes its way into the crankcase as the engine operates. Changing the weight of the oil you run has a larger effect on viscosity than the difference between 180*F and 205*F.
I had the oil temp sender in a sandwich plate and saw 230 pretty consistently. All warmed up driving down the highway in 70 degree weather on a bone stock '96 1.8L.

Here's an interesting thought from an uninformed source: Lets say your current car hits 260* spikes during track use with 10W-30. After you install an oil cooler, you only hit 220* during track use. At 220*, 5W-20 is the same viscosity as your 10W-30 was at 260*, so in theory, you could switch to the 5W-20 because you would be at the same viscosity as before, but at much safer oil temps. Would this help free up a little bit of power safely?

So the Mocal adapter has no ports for sensors does it? So would the preferred method to measure the temp and pressure with this kit would be to add a sandwich plate as well as the Mocal adapter?
Block - Factory 1.8 warmer - Mocal spacer - sensor sandwich plate - filter?
Seems crazy

Another option is an inline AN adapter in the line going to the cooler. It won't read accurately until the thermostat opens, but you don't really care what the oil temp is below the thermostat opening point, right?
Here's an expensive pre-made one:

I have a 13-row Setrab on the FM steering rack mount with -10AN fittings. It works pretty well, but is definitely in a vulnerable location. One additional downside is that 13 rows is the max you can fit, I have a 19 row Mocal that I originally bought to use with it, but the fittings want to be where the sway bar is. On the plus side, the lines are nice and short. (Note that the kit FM sells uses -8 -- I agree that's too small, so I built mine with -10)

you can use this thing - its cheap ($13.97) and doesn't need extra fittings
