6G Celicas Forums

I'm new to the Import side of cars and just recently picked up a 94 Celica ST to get some better fuel mileage and a winter car.

The car has pretty high mileage at around 227k and I was thinking if I needed to swap the motor, what kind of vehicles could I source it from?
I've read on the forums but couldn't really find anything about the different 7afe's specifically that would vary from one car to another so I wanted to ask.

I'm lost in the import market, I've always been on the domestic side of things with sbc's. Any help would be appreciated and it's not a dire need to know
just mainly a curiosity to learn in case I ever have to venture down that road.
