Will Mocal Sandwich 20mm fit on 1.6?
Flying miata has a 1.6 version of the Oil Sandwich thermostat that includes a spacer and longer pipe thread for the oil filter.
Does the 1.6 really need it?

The sandwich plate itself will fit without the spacer, however it's unlikely you'll be able to screw hoses onto the fittings. The surface of the filter mount on the block is recessed behind some obstructions, and the purpose of the spacer is to bring the plate far enough out that the hoses will clear the obstructions.
That said, IMO the Mocal plate is junk. The thermostat on it seems to either bypass too much oil when cold or open too soon, because on the street it took half of eternity for my oil to reach 180°, and it never got much above that.
I replaced my spacer with an OEM '94+ cooler, blocked off the hose ports on the plate and kept it around as it's where my oil temp sensor is. I'll see if I've still got the spacer somewhere.

Joe, the thermostat has to flow SOMETHING. Otherwise, when it opens, you'll get a sudden oil pressure drop. My 6x11" cooler with a 180 degree Mocal thermostat runs about 190 degrees around town on a hot 90 degree day, and about 175-180 on the highway.

Yes, it does. Problem is that mine, anyway, felt like it was flowing too much, too soon.
After I installed my 1.8 OEM oil cooler, I discovered an unforeseen benefit of it. First thing in the morning, it acts as an oil warmer! Oil comes up to temp faster than stock (1.6 design) in this configuration.
I've not have any overheating problems since installing it- even during the five hour mountain run we did a few weeks ago oil temp never went above 220°. For those who are doing bona-fide track events and genuinely do have a problem, I believe a much better solution would be to place a small radiator ahead of the main radiator, dedicated to the oil cooler coolant. Put some "Ys" and a ball valve in there, and you can select between "normal" and "super-cool" on the oil.
Tell you what. Pull your oil filter, stick your head in there, and you tell me.
Personally, I don't see how any plate will fit on the 1.6 without a spacer. There's just not much room to route the hoses.
That said, I just checked and I do still have a spacer sitting on the shelf. $25 gets it shipped within the 48 states. You'll still need to come up with a longer pipe, as mine's in use with the new cooler. The stock pipe off any 1.8 Miata engine will work.
