AboutMp2 Expertise I prefer to answer questions relating to the Miata since this has been my area of specific
expertise since 1991. I can answer questions relating to the other Mazda models however
some limitation of expertise may reduce my accuracy.

ACT clutch seems to have gone out on my supercharged 92 after around 32,000 miles. When pushed to the floor there is no resistance. Cannot start the car without it moving unless jammed in neutral. Is there a chance I can adjust the clutch to have a bit longer life using the adjustment rod under the dash? Or do you think the pressure plate is shot and will need replaced. Fluid levels are good, no leaks.
thanks,
Aaron
Answer based on what I read, you either have clutch hydraulic failure or your release bearing has come apart.
While someone pumps the clutch pedal slowly look at the slave and see if it is engaging the clutch fork. If it is and it moves full cycle then the release bearing is history. If the bearing has come apart then you will be able to move the clutch fork by hand with little resistance.
If is doesn't move when pumped then it may just be an internal hydraulic failure - new slave and master cylinder time. Replace them both as a pair, especially with an ACT they have more Ft. Lbs. than stock and put more stress on clutch hydraulic piston cups and seal faces.
I'm confused about one part of your text. Can you place the car in neutral and start it? Does it run no problem out of gear or does the transmission not disengage from the motor, ie it tries to move where ever the shifter is. If so what gears. Can you get it into reverse?
What ever you do, do not force it into or out of gear running or not you will break something and create a more sinister issue.
