NO but some are.. RB20 and RB26 are close and RB25 head is totally different, Rb25 and 26 can swap crank and pistons...

The block of the RB25 and 26 are virtually the same. (although from different casts) The head from an RB 26 can swap onto an RB 25 for better flow, a not so uncommon practice overseas. if anything the odd man out of the bunch is the RB20.
