Default alternator question

I have a 2000 4cyl 2.5 ranger and i was looking at sites for bigger alternators (300amp) and everyone i look at it says that its for a 6cyl and the option for a 4cyl isnt there. Can i put a 300amp alternator in my truck?

You can buy a 130 amp alternator case and have it upgraded to 200 amps and it will fit in the bracket perfectly. You would have to upgrade the hot wire to the battery with #2 or #4 wire minimum.
To put a 300 amper on there you would have to use a different bracket and alternator plus it would be tough with all the shit that would be in the way.
The 130 ampers don't cool very well if you upgrade them past 200 amps.....been there tried that.

If you have AC, you would probably have to ditch it to fit a 300 amp alternator in it's place. I think you're better off getting two a dual alternator kit and use two 130's so they fit.

Now the big question also is WHY. What prey tell are you doing that you need 300 amps in a Ranger? And I hope you don't expect to get that capacity at idle.

Maybe he has a 10,000 watt car audio system or a REAL BIG cb radio amplifier. Mean Green makes some real big units as well as Leece Neville or powerline.

I am looking at doing this. I can't figure out confidently which 130 amp alternators fit the stock mounting brackets. I know this thread is old and this is what I found when I searched.

This style alternator will fit.....here are the 95 and 130 amp alternator cases you need.

That may be the most helpful post I have found on the internet thus far which either means I suck at searching or there is too much info.

Any idea of some other cars that have this case?

I don't know if any other Fords use that case...I know the F150s don't.
The only downside with those style alternators is their heat dissipation.

I'm not terribly concerned about the heat dissipation as I will only be drawing a large current for short periods of time.

I just need to figure out what vehicle I can go to the scrap yard and pull it off for cheap.

Some pre 1997 F150s use that alternator depending on the engine.
