+1 on the ARP versus factory rod bolts. sand_man's spot on there.

However, discussion on the engine rebuilding forum indicates that a stretch gauge is vastly preferred over torque or angle measurement methods, for accuracy. And you would have to split the case for that...

Also probably worth noting that the Turbo Carrera owner's handbook has a specific warning:

Maximum speed of 6,000 rpm should not be exceeded for normal driving

Increasing engine RPM to 6,700 rpm is only permissable for short periods if needed for quick acceleration
78 and up, the CDI does the rev limiting is my understanding. But the "6800" mechanical limiting rotors can cut off quite high.

I know it's Auto-X and you're trying to save a shift, but 7,000? Power's falling off a cliff on the stock motor by then, surely?
'77 S with '78 930 power and a few other things.
