Alternator upgrades/replacement from different vhicles

#1 Post by Mitsuru » Fri Dec 03, 2021 10:33 pm

I'm having trouble with getting a suitable higher ampage alternator than those that came on stock Chrysler
1994-2005 Neon 90amp
1997-2005 Voyager 120amp

I can easily get BMW N47 180 Amp Alternator Fits 1 3 Series E8X E9X 318D 3120D 118d 120D 8507624
BMW Alternator - 180Amp 14V
OEM Part number: 8507624
Fits
1 Series E81 E82 E87 E88
3 Series E90 E91 E92 E93
(Only Diesel Models with the N47 Engine)

There is a load of those on ebay for twenty quid!

So now the questions. Has anybody done something similar? How hard would it be to do?

You need to choose an alternator with a built in regulator. Recent cars have the alternator controlled by the ECU, which would probably not be compatible with your Neon. The other factors to consider would be the mountings, whether the pulleys line up and the type of pulley. Alternators of the power you're considering will need a ribbed belt, not a V-belt.

CheapBMW E91 N47 alternator arrived today.
I took the black plastic rear cover off to see what the regulator looked like. What am I missing? The plug to connect a field generator signal or control wire doesn't connect to anything or am I missing something!?!
