-You can switch bell housings with a z32.
-You can use a rb20 tranny on a rb25.
-You can use a ka trany with a rb20 bell housing.

correct. the cheap way is to use an rb20 tranny. all the clutchs and flywheels are the same (except some 26's are pull type)

i used a 26 front bellhousing on a z32 5speed N/A tranny with a maxima slave cylinder (both bolt holes are on the bottom)

you could also use a 25 front bellhousing on a z32, the 20 won't work because it's too small.

You can use the RB20 tranny.

Have you taken the tranny to a shop? It's pretty much the same internally as the Z32 tranny.

you can use a complete rb20 tranny, but you cannot use an rb20 bellhousing on a z32 or rb25 tranny because it's too small. you can however mix and match z32, rb25 and 26

we use it on SR20DET engine for our drift car. What we do is cut the bell housing and weld half of the SR20DET to the RB25. If you want that, Garage BOSO can do it or send it to Japan they also do it.
