the CASES are interchangeable [below 89 z31 is a borg warner transmission, and is excluded]. the z32 bellhousing will NOT bolt to the rb motors. the point of the discussion was that the cases will swap, letting you use a different transmission. you still have to aquire the proper rb bellhousing/front case.
and in the case of the z32 transmission, you may have to modify the shift linkage/driveshaft inorder for it to work in an S chassis.
it would be best to set the car up to take the hybrid transmission in the first place [may need a modded transmission mount, shifter, driveshaft] so that if you ever need a new transmission, you can use one availible from a junkyard instead of paying and waiting for a JDM transmission.
