  • 120 series 6 speed behind a 1kz in a 90

    Has anyone had a 6 speed from a 120 in their 90? my gearbox is on the way out and im looking to upgrade rather than replace, i know the first few years of the 120 offered a 1kz and im guessing with a bit of luck they will bolt in. the bellhousing is sure to be the same pattern but the crossmember may not fit?

    1KZ 120s have the 5 speed R150F not the 6 speed RA61F. They came in with the 1KD 120s in aus. They all have the same bolt pattern wrt to the bellhousing, though the RA61F doesnt use a spigot bearing in the crank. You might want to consider gear ratios as the 151 has a much taller 1st gear than the R150F in the 90s.
