upgrading alternator?
I know someone had 3rd gen alternators converted for bolt in, but from what I hear he's been done with that for some time. Was wondering if anyone tried using a 70A from a 86-88, or if there were any aftermarket bolt ins. the current now doesn't seem to be sufficient

Wait, FD alternators bolt up? Do the connections match? I know that S4 alternators are a direct swap, but I thought that everything above S4 used different connections. Is it easy to swap the connections?

Ya its deffinately a good upgrade, I really enjoy mine and I have only used it for a short period of time!
I have one question though, does a bigger alternator actually decrease a cars hp because of the extra force required to turn it? Because I was thinking about this and a alternator shouldn't be harder to turn, because it just creates AC current by rotating inside of a bunch of coils of wire.... If anyone has a second can you elaborate on that? (sorry for the semi-hijack...)

Whenever you move a magnet past a coil of wire, it creates a magnetic field, and an electric current in that coil.
It's basically the same principle as an electric motor, but reversed:
