Extra baffling for the oil pan.

The other thing to remember if you're using the Accusump as a hydraulic accumulator it's only going to push oil for the amount of time the Accusump has more pressure than the engine... may not be long enough to get that quart into the engine.

Doesn't work that way... if you push a quart of oil into the hose, a quart will come out (assuming the hose is already full, if not you may get less).

Sorry, looked as though you were thinking that you would get a quart and a half into the engine because of the hose.
Is a 1 QT enough... depends on several things: viscosity of the oil, flow capacity of the hoses/valves, time the engine is low on pressure. These things all change from car to car, different ambient temps, different tracks.
If you're worried about it get the 2 Qt, if you're really worried convert to a dry sump.

Is the 1-way valve required? My oil system goes: pump-plate-cooler-filter-engine, so I'm not sure if I need it or not. Also, can I stack a Mocal plate and one of these? That would make install too easy.
One other idea: Put a low pressure alarm on the pressure side of the Accusump; it will buzz you *before* you actually lose all oil pressure.

I decided when my rebuild goes in accusump will also be installed. Pictures of odd damage to a rod bearing attached.

I used pressure sensor S367 from O'Reilly auto in my remote mount filter, and then have it wired up to an LED in my pillar next to oil temp. It cost around 10 dollars total for the low pressure light which is rather annoying when the car is not on but the ign is in the run position (so you know you'll see it!)

Other than cost, what is the down-side of the electric valve? Seems that the set pressure points of the EPC valve are a nice feature. 20-25 PSI, 35-40 PSI, and 55-60 PSI versions are available.
Description of the 35-40 PSI valve from Canton Racing's Accsump website:
"This Electric Pressure Control Valve Kit is for a discharge/refill of 35-40 PSI. These valves have the convenience of an electric valve for remote mounted units and the rapid refill rate of a manual valve as required in racing. The E.P.C. valving will only allow the Accusump to discharge oil when the engine’s oil pressure drops below a predetermined level and only refill when the pressure rises above that level. Comes with the regulator, electric valve, a pipe nipple, a toggle switch, wire, terminals and instructions."
The #1 reason I like the idea of the EPC valve, is that I'm an idiot. With my luck the one time I REALLY NEED the Accsump to work would be the one time that I forgot to open the valve.

The peace of mind is worth $150. I need to make up my mind...

The Manual valve seems bullet proof as long as you remember the proper sequence of flipping the valve and can place it where you have access.
The EPC Electric valve seems like with the pressure discharge/refill window and the rapid flow capability would be the functionally the best. Question is will it operate as flaky as so many other electronic control devices I have fiddled with or will it actually consistently and reliably work as advertised?
Also with the EPC valve which of the available discharge/refill pressure options would be best for a miata engine, 20-25, 35-40, or 55-60?

With the amount of money spent on an accusump (3-400$) you could probably get a decent dry sump kit started.
Finding a pump for cheap is the only real problem, everything else can be made diy style.
Then you wouldn't have to worry about the accusump actually working properly, but it will cost abit more upfront.
Cost of Accusump + another rebuild when it ***** up > Dry sump diy system
