Alternator upgrade... 55 65 or 80 Amp

[ymanchik]

Want to upgrade my stock alternator. Does anyone have an 55 or 65 amp alternator from 1977-83 E21? Or the 80 amp one from a 1984-85 E30? Thanks

I have one of the 85 amps that will bolt right in.  It has been tested, has new brushes and voltage regular in it.  I can ship it to you for $120 total.  If you look at my other postings you will see photos of it for sale.

Okay, are you sure I don't need the bracket for it as well? I though the 85 amp ones you needed the bracket too. 

 

Just want to confirm that this will bolt right in. Thanks.

No bracket.  It is a direct replacement.  It pops right in.

You do need the bracket. I have an 85A installed on mine. You have to have the e30 bracket.

What bracket are you referring to?  There is the straight style belt tension bracket, that is standard on the 2002. That is what my alternator uses. 

And the part where the alternator pivots, which is also standard, and my alternator fits right on to.  I did not need an e30 part.

There is an extension bracket off of the e30 motor you need otherwise the belt doesn't reach. It basically pushes it out an inch or so. I'll post a picture later when I get out of bed! Haha

The bracket does bolt straight onto the m10 block which then makes the alternator a bolt on.

My alternator is the same size as a stock 2002 alternator.  It is 85amp though.

It is hard to tell from the photos but you can see that the pivot bracket for the alternator is the stock bracket from a 2002.  And the slider bracket arm, although the alternator is near the end of it's adjustment, is a 2002 stock item as well.  My alternator is NOT a 318 alternator. It is a stock sized alternator wound for 85amp and has an internal voltage regulator.
