Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Are all 996 3.4 motors from the different respective model years cross compatible assuming you were to swap over the ancillary components from the original engine? I assume there is no difference in the actual engine between manual and tip?
I dont think so, I'm sure someone more knowledgeable than me will confirm. I know the fuel rail on my 2001 3.4 is different from earlier 3.4 engines and again different from the 3.6 motors. Porsche only part as well (ker-ching for Porsche). I'm sure there will be some common components but I dont know what they are.

Could be wrong, but I *think* the alternator is slightly different between tip and manual - to do with the clutch on the pulley?
This is a source reference. Confirm exact model applicability in the original material.
