I'd certainly expect Randy's pointed post:

"Lacking the knowledge of simple rotor gear re-indexing (if that's the case) is telling of an ongoing deficit of comprehensive understanding of rudimentary elements, let alone the operating principles of boosted engines with mechanical ignition devices."
Yowch.

would read diferently now if he read my prior post:
*Distributor lines are disconnected and effectively capped (pinched via clamps) per the 2004 builder's recommendations.
Both vac and retard lines are disconnected from distributor so as to not create a possible imbalance of plate movement.

*Two different timing lights were used. Both show the same measurement.

*Reindexing, yes of course. I've done this as a matter of course on 3 other non-porsche rebuilds I have done. One engine had distributor gears so coarse that reindexing made the adjustment slot go the completely different direction - ie full bottom to full top.
Didn't want to reindex and have it not work - it is a fair bit of work to get to the twin plug distributor (IC removal, very very tight access)

*Timing on the 930 has never been altered by myself.
It remains where the 2006 builder set it.

Posting here to glean actual experiences is valuable to me.
It sounds as if reindexing is indeed a functional possibility.

Making rash assumptions via couched and wordy remarks that imply I f'd up when I didn't.......come on.
