I ordered up a differential out of an auto g35 to take the ring/pinions out of and stick in my m/t rear end. I can see that the differential is larger from end to end on the a/t rear end, as well at the ring gear being thicker from side to side.

Trying to figure out how people get the 3.3 gear ratio in a m/t car with an aftermarket limited slip because the os giken diff would put the ring gear placement in the wrong spot for the a/t housing to work and the a/t ring gear is to thick for it to work in the m/t housing.

Are people machining the a/t ring gears to make this happen? Any help is appriciated.

 

You cant do it with an OS giken as far as I know. I think only Quaife and maybe one other company have a kit for a 3.3 FD

 

Wish the shop I bought the parts from wouldn't have recomended the a/t gearset...

anyone need a 3.3 fd?

 

you need the OS for an automatic, or Quaife or Cusco also offer it

manual gears (3.5, 3.7, 3.9, 4.08, 4.3) go with manual transmission diffs, auto gears must use auto diffs
