I am in the market for a new alternator for my 2.7l. I currently have a SEV Marchal. It is not working. The fan housing that I have is from a 2.2e. Any recommendations of an alternator that I can install? I know very little about alternators on 6 cylinders. Any advice is much appreciated. Cheap and reliable is a major plus.

The early 911 alternators were externally regulated, just like the 914-4 alternator. You can use a stock relay board and the regulator mounted there, but you have to have the correct engine harness to hook up the regulator.

A better way is to buy a 911 SC or Carrera alternator. It has an internal regulator, and it is a direct bolt on to your engine. The only wires you need are the big heavy red one from the starter, and the blue one that hooks up to the alternator light.

And yes, you can change a six alternator with the engine in the car. There is an article on this site that will explain how.
