Hi,
I see tons of threads on upgrading a V6 alternator from SI to CS130 but nothing for the 2.5.
Is there any difference in the procedure that I need to be aware of?
It looks to be a two wire set up so i know I'll need to adapter plug...

Yup. Put one on my Indy's engine - fits the stock alternator brackets.

Just FYI, the 88 Fiero V6 uses a CS alternator. It uses a serpentine belt, whereas yours uses a V-belt. So if you swap pulleys and grab a wiring pigtail, you should be good to go.

As the others have said....it is as simple as swapping the pulley and getting the wiring pigtail. I used a stock alternator from an 88 v6 in my 84. Do not try to go with one of the oversized ones (CS140)....it will hit the intake on the 2.5.

The swap was pretty straightforward...mine is an auto, so it had to come out the top. The upper alternator bracket isn't that difficult to remove....but don't even think about removing the lower one, those bolts also hold the engine mounting bracket.

No. 87-88 Fiero 4-cyl alt has wrong front case. It has 120° mount points.

Old L4 use same alt as V6, 180° mounting, shown above. Need correct V pulley.
