mazda manual says G5M-R ratio is 0.795
but in other places (forums) I read ratios of 0.837 :/
Damn! Stupid old mazdas! there's no info about the 626/mx6 gearbox
EDIT: found this
got the info from here:

need the "RF" gear but RF engine is diesel
F8 5th gear engine ratios are same
also BG mazda 323 BP sohc have better ratios for economy but it's a different gearbox! (F5M-R)
