most of the above also applies to the ae101 sereis, and others
iv missed a couple out for things like the spacio cause i didnt really think many cared about them!
if you have a car with numbers that are different let me know and ill decode it for you

to clear a few misconceptions up.....
gearboxes
BZ-R are all 6 speed manual.
BZ-G can be either maual or auto all 6speed after 4th 97
BZ-V can be either 5spd manual or auto, untill facelift in 4th 97 then they are all autos, but sports type but with out LSD. which i find odd. i have yet to see one of these.
diffs
BZ-R are LSD from factory
BZ-G are open if non s/s. prefacelift s/s are LSD. all facelift have s/s but are open
BZ-V are lsd if manul, autos are open
thatll do for now, any questions?
