well GrN motors is pretty much stock RA motor, that's the idea, minus different inlet hose, restrictor and retuned ECU
GrA is like open class, do whatever you want, just don't forget to put a restrictor in there

then there are occasional "factory freaks" motors that have different heads/pistons etc. made for R&D, but you don't see those often
