T18 is a corolla, it ran a T series engine 2T-C or 3T-C? T Series gearbox, T series diff etc.
The reason KE70 and AE71s are usually compared together is the body/chassi is entirely the same, they only had slight mechanical changes. KE70 ran a cable clutch, AE71 ran a hydraulic clutch. KE70 used a K40/K50 gearbox, AE71 used a T40/T50 gearbox, KE70 has a different tailshaft/diff to the AE71 etc. etc...
