Which alternator in a 1992 964 engine

I have a 3.6 transplant in the 911 and its now letting the voltage dip lower than I am comfortable with, showing at times 3.3 volts in the system while I am driving.

Bought the engine 7-8 years ago from a fellow Pelican and its done fine but am guessing that its got over 100,000 miles on it and probably time to have the alternator overhauled.

Anyone have any idea what brand and amp rating on this puppy? I usually take my alternators to a local shop and they always ask me what model it is and sure would like to know before I head in there to tell them.

Anyone have any ideas on this? It was off of a 1992 964 that was a German spec car.

Thx Joe

It is common to see Bosch alternators in these cars.

964 603 156 01

115 amp rating
