A stock FD alternator should have enough juice for anything I'm running now, plus whatever I might add down the road (e.g., stereo upgrade/e-fan).

The damn thing barely idles @ ~13.0VDC.
Loaded down at idle, it runs about 12.0VDC.
The seller was named "HighAmpSpecialist" or something like that.
One of my previous posts talks about having good experience (rebuilt starter for my FC) from an eBay seller "AceAlternators" (or something like that), but they don't offer an FD unit anything over 130A now...
They used to have a 160A, but I haven't seen that unit for sale for a few months now.
There's another eBay seller called B&R or something, and they offer FD alternators in the 160A range for about $200?
Check the feedback. and there's negative comments of the upgrade alternators being bullsh*t.
I would highly recommend to go with a MechMan unit if you got the bucks...
Last time I checked, it was about $330?
Yes, it's a little pricey, but these things are rated like 250A...

Yup, I recall you mentioned AceAlternators on ebay, and took a look there. They have S5 drop-ins for about $140 that are rated 110A, which is roughly the same as a stock FD alternator. They didn't show anything in stock above 110A. One year warrantee on it FWIW. I might give them a shot as it's enough juice for my current & future needs, and I can reuse the dual belt pulley I already have.
Also heard good things about the Mechman alternators, but that is overkill & too much coin for my needs.

I run a stock FD alt and I seem to not have voltage issues. Although I've rewired the car and the charging and the main distribution wires so voltage loss isn't a concern to me.
That being said I don't get a full 14.4volts, it's usually around 14.1-14.2 but I'm still playing around with resistance values on the excite wire.

Stock S5 alternator is about 70~80A at most; I'm just looking for a better reliability margin to ensure the fuel pump gets enough juice when I'm running all the stock electrical loads, and any future changes (big stereo, e-fan, etc.). So something in the stock FD range (100~110A) should be fine.
