As the topic says, what is the max output in amps of the 01-04 civic stock alternator?

i just changed mine i think its somewhere around 80-95 max mostly stay way low at idle though due to our poor grounding system

No worries my grounding system is ****

I think it's 65 amps, but I can look in the manual later.

65 amps ouch... thought it was a bit more than that

I don't think it's in the manual, I would have seen it

 
Rep Power: 370

Most say it's 70 or 80 actually. I'm more inclined to believe this little bugger is a 70A alt. Boo-urns.

napa sells a 60amp replacement for our cars. so thats probably the same as stock? canadian civics might have a beefier alternator

I told you Megahurtz! Our alternators are weak and are 70 amp.

Pushing a huge system (above 1000 watts could do some damage in the future, or at least keep you changing out alternators regularly. cheaper to go HO.

btw where is a good place to get stronger alternators for our car?

right here

not a bad price

or get one of the Stinger 200 amp models

www.stingerelectronics.com

or get one from Dominick Iraggi

According to the service manual, it IS 70Amps at 13.5 volts.

So there

Yeah, that's nice. Worth it if you have a huge amount of ICE in the car.
They basically rewind a stock alternator and put stronger diodes in it as well.
I wonder if the ecu would complain....

found an ebay auction that has a 170amp model http://cgi.ebay.com/ebaymotors/ws/eB...category=33573

i think its the same brand as the one in the 4alterstat.com.

couldnt you just get a big alt out of a truck or SUV from a junkyard and fabricate something to hold it in place

 
Rep Power: 787

Ya probably, but the question is, is there space for it?

 
Rep Power: 787

Why would that alt not fit Canadian made Civics?

I was wondering that?!

Maybe someone should point out that IF you actually drew 170 Amps out of an aftermarket alternator in a civic, 2 things will happen.

1) At high current the alternator gets harder and harder to turn, bringing the engine horsepower down to what..... 45 HP? LOL.. Seriously, it WOULD pull hard on the motor.

2) The wires would melt, unless you upgrade all the major plus and ground lines.

A non-civic alternator may work, but because ours is regulated by the ECU, there's no telling what would happen.

Best bet is still an optima battery for most cases.
