928cs

Don't be so modest
This was fun to build this database and it has helped us a lot.

But remember that ANY Porsche Center can provide you more information, if you are the owner of the car, as illustrated here:
https://rennlist.com/forums/928-foru...okup-help.html

An advantage of our database, is that we can make some statistics, like the number of cars with a given equipment.

On some years there are. For example different throttle body on some S4 where one vacuum line connection is located at different position on C03 cars.

Yes, there's that diagram in the '87 Service info tech showing the C02/CO3 difference.



And there are a million different vacuum diagram stickers specific for C02 vs. C03 markets, but there's no difference in the vacuum diagrams, for whatever little that's worth.

Rob, here's the vin for the '87 I bought yesterday: WP0JB0923HS861515. I spoke w/Precision Motorwerks (Sooooo knowledgeable & nice!!) and they told me you were the expert to ask what the leather color name is. I know it's generically some shade of brown, but I can't seem to track down the name..definitively. Mahogany? or Cork? or...? Any insights you may have are much appreciated. Thank you for all your efforts Rob.

Thanks for the welcome Rob (and for the leather color & vin info). I'm excited to be a new 928 owner as well as a newbie here @ Rennlist. The RL Members' experienced & granular depth of knowledge on all matters 928 is truly incredible. The fact that the RL Members openly & readily share that knowledge in order to help any 928 enthusiast who asks ...... is phenomenal!! Thank you all.

Well, it's not the 'correct' engine for that VIN number, but it's a better engine than the correct engine.

M28.11 8200610 is is a 300 hp 4.7 liter motor from a 1980 Euro S. Well, at least the short block is- you should verify that the intake and cams are Euro-spec.
