Are all 1.8 L 7AFE engines rated for CA emissions requirement?
No. CA models had a pre-cat and a cat. Fed models only had one cat. Pre-OBD-II 7A-FE fed models (1993-1995.5) didn’t have EGR whereas same model year CA did. Might be other differences I’m forgetting about too like downstream O2 sensors.

For the purpose of doing an engine swap, as long as the engine were to have an egr port, assuming all what you stated above is correct, I would be good to place a "mystery 7AFE" engine into my CA emissions 97 corolla?

Is there a way to designate a CA emissions engines from the other emissions types engines?

If you have a 1997 you have to make sure it’s an OBD-II version as the OBD-I version (1993-1995.5) has an adjustable distributor and lacks a crank position sensor. Other than that I think you’d be ok.

The bare blocks are the same, head, cams, intake manifold, and oil pump and timing sprocket are different.

Thought I saw some funky going on with the left rear tail light.

ok let me start by saying I am definitely in no position to start messing with my car’s fuel injectors since my car can barely make it up the hill without sputtering like a dying animal. With that being said…

About a few months ago, I was thinking of the simplest bolt-ons and ways and things that can improve my cars performance. Obviously I would start with a tune-up (spark plugs, wires?, oil and filter, distributor rotor and cap, fuel filter that hasn’t been touched AFAIK, etc.) but I wanted to go beyond that. I’m in no spot to start taking the engine apart and messing with pistons, turbos, bearings anything relating to internals. Then I found this thread on 22RE injectors and it’s been on my mind since. I wanted to know more so I reached out to the OP thru Instagram and YouTube, nada. Like he just got up and left his socials. Ok. So I look up the injectors on eBay by Osidetiger Fuel Injection, they have the 4 nozzles, specs, and harness and everything the guy mentioned. $160 shipped so I’m putting it aside for tax season.

2 minutes later I’m looking up “fuel injectors” and I find 12-hole injectors that claim to be “modern” and are meant to fit the 7th gen engines. Description says it’s for the 1990-1996 Toyota Corolla 1.6L/1.8L (4AGE/4AFE).

This makes no sense to me since the 4- is supposed to be 1.6 from what I know. As I’m also typing this out, I found another thread on another Toyota forum (didn’t know there were this many) about 12-hole injectors on a 4Runner and the good things that came from it.

Conclusion, I need to do some more forum searching but this doesn’t look to be difficult in any way shape or form. I would love to buy the 22RE injectors and the 12-hole ones and see what actual performance gains I could possibly get out of them. But before that let me fix my pre existing issues first and make my car roadworthy again…

Injectors are pretty plug n play as long as the parameters are the same or similar. Height, feed type, o-ring diameters, working pressure, resistance, latency, and spray volume. More holes may not be more better if the holes are spraying fuel at the sides of the intake port instead of at the intake valves.
