The ratios for 5th and final drive are as follows
C52 (Gt turbo)
5th 0.815 Final 4.058
C56 (glanza v)
5th 0.815 Final 4.312
C150 (ep82 n/a not inc 4wd)
5th 0.815 Final 4.058
C153 (starlet gt turbo) yes there's more then one lol
5th 0.725 Final (unlisted)
I hope this helps. By the looks of things the I or difference really is in the c153 gearbox but I doubt it's going to make all that much difference.
