When I yanked the pulley I did not see the vibration damper and it was not connected to the pulley. I don't know what was there. That is odd. Either I just missed it, but I don't think so. When I pulled the NA pulley off, the vibration damper came right with it so it would be tough to miss it, but who knows. I was there yaking with the guy who initially made claim to the engine for almost 2 hours so perhaps I just moved on without paying attention ...

I guess the next step is to locate a turbo vibration damper and see if the that will mate to the balancing disk. If not, I can get another NA pulley - damper at the yard here locally unless they crush the car by this weekend. Overall, not a big deal since I can simply replace the seal to get rid of a pesty oil leak and install the original stuff and abandon the idea of a duel alt pulley. Not sure there's a way to mod any of these parts without major R&D effort and it's not really worth it because the ultimate goal is the turbo engine. It just would have been nice.

So far, I know that the pulley and vibration damper are neutral balanced so they are interchangable per all the posts on the net. The only thing "balanced" with that engine is the balancing disk. A donor disk can be balanced by matching it with the original disk.

The only issue I guess is will the balancing disk bolt up to the crank ?????
