Sounds like you need to buy some Porsche manuals.

I need more info on the 964s and 993s. I have all the FWS manuels for the other models.

Might just have to do that soon! :)

Brian, unless someone provides the info first, I'll try to get you the 993 info when I'm back at home this evening.

Jim,

Please do so, thanks!
