The 5th gen CRV vs. The Civic Si engines.

I've been cross referencing all the parts and part numbers of these engines; internals, external parts, etc. I have found that the only differences are the turbo inlet pipe, resonator box on the L15BE, and thar one has a torque converter and the other a clutch. Even the turbos are the same. I know the factory tuning is slightly different - not worried about that since I'm running a KTuner.

Does anyone know if there are any other differences between them?
