Interchangeable trans on rb25?

[cynxe]

What transmissions fit the rb25? I cant seem to find anything on them.

[Sileighty_85]

Any RB transmission.

Anything else requires heavy modification to use.

With rb bellhousing, Z31 '30a or Hardbody '30a 2wd will work to effectively create the same trans as the RB25 unit... the other option is using Z32 '30a on it, but the shifter will be pushed rearward a lot.

Z32 works also.
Iv also heard of people also using diesel gearboxes from the 2wd td27 Frontier

Thanks for responses guys,

rb25 trans works on KA's, so I would assume the KA trans would work on an rb in a pinch.

That would be extremely convenient

From what i've seen the rb trans bolts on the ka, and only one bolt hole has to be enlarged a bit on the bellhousing. So i'd assume it would be the same the other way around.
