Can anyone tell me what year model my ecu/motor is going off the part numbers I posted above? Cheers

Did you try googling it? It is from a JDM late 1992-1993 gen 2 3sgte.

i did google it but i suck at the internet haha. thanks for that. so its 92-93, my question now is will an ecu from say a 91 gen2 work with it? i can't seem to find any differences between the year models, but saying that I'm probably wrong and there are differences

Nope you need to use the same part number (A USA ecu might work but don't bother) 
 
Another plug in option is an AP Engineering Power FC but that would need to be tuned.
 
Just get the exact same ecu if you intend to swap it out. Think someone offered you one on the first page.

Technically you could get a 89/90/91/early 92 ecu to work on your car but you would need to change some of the wires around on the ecu plugs.
If you mainly need a speed cut so you can go faster then 180KM/h you can just buy a small module to do that.
