I have a 1987 911 Carrera 3.2 non-turbo that carries an IDC of 930/25 stamped on the engine. Can anyone tell me what the numbers designate?

930/25 is the factory engine type number for the 1987-1989 3.2L Carrera engine with catalytic converter. By itself, it doesn't really tell you anything else.

Thanks, Bill. I guess it just tells me that if the engine was swapped out, it was swapped with the same kind. Thanks again. Bill - I'm still a newbie Porschefile -I thought 930 was the turbo. Is it appropriate to refer to my normally aspirated '87 911 as a 930?

no, your car is a 911, a 930 is a turbo charged variant of the 911 chassis, but the share part # prefixes back and forth on the parts, but if its got fat fenders, and a tail with an intercooler hiding in there, its a 930 which has much wider fenders than yours and mine, heres a 3.2 like ours

doesnt that mean its a 930 case (ie shares the same engine case as a 930).

all 912's and 356's have case numbers 616/XX (xx is the year.. a 1969 912 will have case number 616/40)

im asuming it may be the same kinda thing for those engines?

in most cases yes, just like the 996 TT still uses the 964 case even though its water cooled

it IS a 964 case so it has naturaly a 964 number
good thing as the water pumper case can barley cope with a meager 300 let alone when they bumped it to 3.6 liters, but that 964 case can take in excess of 800hp all day long.
