Well, I also have the porsche factory manual for the motor but it does not have a lot of the critical specs needed to machine and rebuild an old motor.

For example I will be bumping the compression so I will need information on deck heigth limits that you can't find in any other resource.

Since I am getting my machining work done I need a lot of other measurement specs and would like to know what anerobic sealants are recomended for sealing the different metal to metal surfaces.

I have rebuilt a lot of motorcycle engines using yamabond to seal the cases but those kinds of sealants are not recommended for this motor. Since a couple of critical oil gallies pass between the cases and the last thing a 930 motor needs is a chunk of squished out plasticised sealant breaking off and clogging a critical bearing or squirter. There are lots of different anerobic sealants out there so I would like to know what the top racers and rebuilders are using for their cases and heads before I pick one for my engine.

To answer the other question, the case is held together with long steel bolts that pass all the way through the case and nuts. Its part of the reason for the case's great strength since the fasteners arn't limited by having to screw into the aluminim block.

In fact the 930 block is so strong the same block is still used in the new 996 turbos, GT2s and GT3s.
