Hi to all, I'm new to 911's and new to this site. I bought a 1975 targa being converted to a race car for the 3.2 and trans in the car. The previous owner never got the car going. I removed the engine and trans and was trying to get the alternator fan hub mounted up the alternator. I found the hub wouldn't mount up. I find the 3.2L engine has a early fan housing model 901-106-101-5R with a 50 amp alternator.

My question is, with all the electrical things in my 84 911 Cab (car the 3.2L and trans is going into) like heater fans, power seats, power windows... should I find a 930-106-102-3R (or 4r) housing to have the larger alternator or will a 75amp which is I believe the biggest I can get for my housing be sufficient?

Any help would be appreciated.
