3 Rotor Alternator on 13B-REW
Does anyone know if it will bolt right up and does it put out more volts?
I need an alternator and I'm trying to figure out what to do.

The 20B-REW alternator is rated at 100 A if I recall correctly.
The 13B-REW alternator is 90 A for the 92-95 but I heard that the 96+ version gets the 100 A aswell. I know as mine is the 96-98 version & I get the 100 A as standard.

There's an FC guy that sells FD alternators - he thinks the FD alternator is under-rated. It does put out a LOT of juice.
In the Mazdacomp catalog, they list the Cosmo alternator as a high-amp upgrade. I would be VERY surprised if it wasn't a bolt-on.

New alternators from Ray @ Malloy are 165 bucks plus the 75 dollar core deposit. Don't **** around with used **** that will crap out in a year or less. Just get one that fits with no issues. I just ordered 2 from him. He has them IN stock and ready to go. Comes with a new stock pulley on it as well
And as for the fittment on a FD... I know the FD works on the 20B but not for sure on the other way around.

The stock alternator puts out only about 40A at idle. I have a 200A alternator in my car. It puts out 100A at idle. My car pulls 90A at idle with the following components on:
2 fuel pumps
4 electric fans
3 MSD Ignition Boosters (6As, I believe)
AC On
Microtech w/ dash display
Profec B Spec II
Eclipse HU
2 Amplifiers
I was killing my Red Top Optima battery before the alternator because the stock one couldn't keep up. The 200A alternator was made by a local guy who outsources to Stinger. It cost $450 and has a 1-year warranty. I've had it for about 2 months and have had no charging issues at all.
Yes, I know. The engine bay is filthy. The small-town. power-hungry beach cops wouldn't let me cut through a 30-foot section of their parking lot to avoid driving down a dusty road to get to my house.
