There's no point telling her about bad reman units until she gets her car back, and she tells us that something's wrong with it.
Most of the time, when someone gets a reman engine, its in better condition than the engine that was pulled.

Why would I get a remanufactured engine and not a new one?
They are all remanufactured engines at this point. Back in 2004-2005, and dropping off through the years, brand new engines were possible if there weren't any remans available. As engine failures ramped up though, there were plenty of spare parts to feed the reman facility. And no more new engines are being built at all, so if there are any in the parts stream, they are vanishing fast.
Your reman will have new side seals, apex seals, corner seals, oil control rings, and coolant seals. All the little bits. There are only 8 major pieces (pic below), and some of them might be new. You will have at least 1 used part among these pieces though, where Mazda has determined that although used, it's still within specs.
The general opinion here about reman quality though is that sometimes people get engines where the re-used part may still be in specs, but the spec isn't narrow enough, and if you get one that is still 'in spec' but much more worn, it can dramatically decrease engine life.
It's a study of averages however. There are exceptions in both directions (fantastic as well as dead on arrival). You shouldn't have anything to worry about however. Given your mileage, it is likely that your reman will last longer than your original engine.

You know Clarissa the only reason im confident owning the rx8 is that the people on this forum have so much knowledge about the car and there isnt a single issue that hasnt been addressed. With all the problems I had with my 8, I always came here first for advice and everyone here was spot on. They know the car better than the dealer.
Cheers to everyone

95% chance E-shaft will be re-used, cuz that part rarely fails.
Irons maybe 50/50. but the nitrite coating does not last forever it's only 0.02" thick and has hardness of what? 50 ? so if they re-use that, chances are even with brand new housing and small seals, the engine will not get the best compression. not to mention all the things that can go wrong during rebuild.
I just found out my FC's engine was actually a Mazda reman, and it was build wrong. missing soft plugs, wrong water seal direction, etc.

I spoke to Mazda and they said my motor arrived Thursday. They have already taken my old one out. Today they're taking parts off my old one to put on my new one. What old parts exactly will they put on my new one?

intake manifold, oil and fuel injectors, any sensors, clear plastic oil feed lines, crank pulley etc
add plugs, wires, coils, belts, etc...
The only things that come with the replacement block (other than the block itself) is the flywheel, water pump, oil pump, and oil pan.

That means the reman wont make a significant difference compared to the motor i have in there now? I think what I'm trying to say is it seems they're using most of the parts from my old motor and putting them on my "new" one?
I admit that it's a concern I have, but I don't think it's a major concern.
All of your issues could indeed be caused by engine damage/failure/low compression, and if that is accurate, then the reman will fix those problems.
IF the problem is something else other than the engine block or engine internals, then yes, the problem will persist because they are re-using whatever parts are still failing.
If you still have the same problems after getting the car back with the reman installed, then since it was warranty work you should still complain. However, I don't think you will get ANYWHERE with the dealer at that point. I'm sending you a PM with my contact info to see if I can check out your car in person with tools and spares to figure out what it is. If the reman doesn't fix it that is.
But, I suspect that the reman will indeed solve the problem and they were either testing it wrong before or it's a different problem that isn't uncovered by compression testing (like initial coolant seal failure).
You addressed everything else already

Riwwp chances are the dealer wont allow anyone that isn't a factory rep or factory field tech do anything with the car, techs at dealers have to follow the manufactures procedures when diagnosing any vehicle that is still covered under warranty,
the trailing plugs prevent self ignition of fuel and/or detonation from leftover fuel the leading plugs didn't blow up.
I thought you put new plugs and coils in the engine before you gave them the car?

So you put in plugs that they disagreed with, then they put in plugs of their own that they insist are OEM, and are now trying to charge you because the plugs they put in are "stopping it from getting hot"?????
What a complete load of BS. Even the description doesn't make any sense even if the plugs were wrong, which if they are it's the dealer's fault! Tell them to either put in the plugs you had in there to begin with (which were new) or leave the ones they put in and give you your car back. Do not let them charge you for that!
Let us know how it is when you get it back and if it's still giving you problems, let me know and I'll coordinate with you getting down to check it out in person.
*I'm seriously shaking my head in disgust at that dealer*
