Hmm I'd be surprised if the plate says 4A-CE, I thought you only got the 'C' on carby models, and I know for sure that the 'E' is for efi....
Sure its not a 4A-FC? (if so...)
AE92 SE 4AFC - 1587cc 67kw 135Nm 13.7 (0-100) 18.8 (400m - 1/4 mile) (not sure it thats manual or auto)
are the specs I got from a quick search.
Also the fact that its an auto won't have any effect on the power of the actual engine (the motors in the auto and manual are identical), it will however lose power to the ground due to the fluid coupling which will make the power to the wheels less.
