Are there any benifits to using RE Cosmo internals in a S4 TII rebuild?

 

What internals?



Im assuming the stationary gears are hardended, so they are better than your s4 ones iirc, and the cosmo rotors are of a higher comp than your turbo ones too.



The cosmo has a higher oil pressure iirc, so maby swaping the regulator might yeild a higher overall oil pressure, however i would question someone more knowledgeable than me on that
