Upgrade to CS130 alternator (Page 1/2)
fierosound MAR 15, 10:34 AM
The CS130 used on the 88 Fiero V6 is an upgrade to the earlier SI units.
It's more compact, better designed and better performance.
I have them on both my 87 GT V6 and my Indy's SD4 engine (pictured below)
They are a direct fit (mounting ears are 180 degrees apart) and only required a connector change.

Get the 88 V6 CS130 alternator - 105 amps (swap your pulley to it if needed).

You'll have to replace the wiring end connectors, or get an adapter from Rodney or others.

Also see my Cave, Rabid-Wombat's CS-130 Conversion for 85-87 V6.
Older L4 use same parts but need to switch pulleys.

Wow that is one beautiful SD4! What is its horsepower rating?
fierosound MAY 01, 09:15 AM
CS130 - 140amp, 170amp and more...
https://alternatorparts.com/cs130-alternator.html

If those aren't enough power, there's a 220A rebuild kit available.

Thanks. We're thinking 250hp. It DOES NOT feel like 4-cylinders when driving.

Would there be any problems with this 220 amp upgrade on stock charging system..

To answer your question. No.
Simplist way to answer this without getting into electrical hoohaw. More AMPS will not damage your system. As the Alternator only provides what is needed for the electrical systems load requirements. It is much worse when you dont have enough AMPS then having too much available.

Question.... I have the cs130 from the 87-91 Corvette. Any issues with that alternator? Also, do I need to add the heat shield?
fireboss FEB 26, 02:46 AM
as long as the mounting ears are in the same position it will....no heat shield needed. I left the cooling tube in mine..
