Full On Retard(ed). The engine, that is.
Dear Gods of MT.Net,
I have recently found out for the past ~2000 miles I've been running the engine -extremely- retarded (The timing belt may be a tooth off, checking it out in-depth Saturday). And yes, I am preparing for the Gods of MT.net to come in here and rightfully mock me for being retarded enough to not realize it until now. As it's my first piston engine I've ever worked on though, I knew I would be prone to going full retard at times - trusted the mechanic who changed the timing belt 100%, and well, it may have came back to bite me.
However, and onto my question: Is there any chance of engine damage? I've been searching like hell on this, way past my bed time even, and I am unable to find anything on this. The major concern I've been able to find seems to be overheating on non-interference engines, with the only real chances for damage beyond that on interference engines.
I'll be fixing the timing issue promptly.

I only trust me to do things right on my cars. Did you alter the CAS sensor position? If not, put a timing light on it and see what's going on.
Just pop the valve cover off and have a look. I seriously doubt you damaged anything especially if you have the stock head deck-height.

The consensus is that a stock engine, with a stock deck-height head is non-interference. I have Supertech pistons and a twice-decked head...I bet it's no longer interference-free. If you really want to know, position an intake valve at its lowest point and spin the crank with a little plasticine between the two.

Thanks guys! You have been a tremendous help and a huge load off my mind!
Lesson learned :(. I only trust me to do work on my RX7s, but the timing stuff isn't something that exists on rotaries. Well, it does, but the rotary analogue has little relevance to piston timing.
No changes to the CAS sensor that I know of, and I'll definitely do that this weekend.
Will do. Thank you Hustler!

Okay, I am having an absolute nightmare getting the timing right.
Dragged in a relative yesterday who is the best mechanic I know, and we had a serious headache getting everything in the timing lined up perfectly. We stopped with what was "close enough" after following the FSM exactly.
When we tried to start it yesterday, he says that it sounds "Too advanced" to him. Video will come soon on it (With audio!) as soon as Youtube stops with their dick-dick-dickery on conversion.

Shorthand: We had to repeatedly set the timing untill we finally got it right. Last time it ran it ran awesomely.

If you are off by 1 notch on each gear its pretty fuggin obvious, but if it isn't obvious, just poke yourself in the eye with a ***** and you might see better.
