Yes,

no it does not matter that they call the engine the same name.... on parts that are not open you may only use parts that came in that car or from a car on the same spec line of the gcr and even then you must swap parts as an assembly. even if the rx8 was listed on the same spec line of the gcr you could not put rx8 rotors in a rx7 case legaly.

Dicks 100% right on this one. If we ran Chevy 350s in IT, do you think we could grab any Chevy piston with 12:1 compression and slap it in our 9:1 motor, just cuz it's in a 350??

No way. This one's pretty clear. 13B is the engine family, but the engines are more like cousins than brothers...
