930 crank
 

Hi All
here is an easy one for those that know, is boss that the flywheel bolts onto the same length on a 930 Turbo crank as a normal 911 crank, that is does a turbo crank project further out of the crankcase than other 911 cranks , I am interested in the version that uses nine bolts to secure the flywheel, thanks Bill.

The 930 crank and the Carrera crank are the same spec. I have noticed there is possibly a difference in the size of the oil passage for the rods..the turbo appears to have a larger hole but I ve never measured it.

Thanks Bruce
I have read that the 3.2 Carrera crank is the same as a Turbo although they are listed under different part numbers and in the UK the Carrera crank is price listed at approximately three times the price of a Turbo one, my difficulty is I need to try to identify the crank in a 3.3 turbo motor I have as there may be an issue with it , someone has taken a linishing disc to the bosses behind the flywheel to provide clearance for them and I don't know why , thanks Bill .

Turbo crank
 

This is an 85 Carrera but the oil galley for the rod looks like a Turbo oil galley as some of the Carreras I have worked with have what seems like a smaller hole with a cut out notch for the oil to feed to the bearing.
I could be wrong about this assumption because I have only had a couple actual known turbo cranks in my hand and when I did compare it to a Carrera that is what I saw.
The back of this crank has the 3 bolts for the pilot bearing attachment circa. 80 to 86
