Upgrade Alternator?

Good morning all....

I have a question on the alternator. Is there an upgraded alternator we can put on the Yaris? I was looking at them on Rock Auto, and it appearsthat an alternator from a 2008 Scion XD with a 1.8 liter would fit, but uses a different pulley (more ribs). They are both clocked at 8:30, and the mounts appear to be close, if not exactly the same. The Scion alty puts out 100 amps.

Just wondering if anyone had tried this, or something similar? I've got a Ford 3G alternator laying around, might see if it's a possibility, as they are 130 amp.

Anyway, I have a bearing going out in mine I believe, so I'd like to upgrade.

FWIW, just bought one for a 2011 Scion, which is 100 amps. It has a decoupler pulley on it, and I will attempt to use it... as I think it will help with the squeaky belt.

Will report back when I get it, and install it.

My dad owns a starter/alternator shop in Newburgh NY, he would know the exact information you are looking for, not sure if he ships out units, but its worth giving him a call

yeah. the pulley swap should be easy. there use to be motor shops in most cities. if you find one they can build whatever you want... or call that guy in NY. shipping shouldn't be more than $30
oh, you're in Utah? i know there is a few in GJ. you could drive there!

Thank you SirDigby! The place I used to frequent doesn't answer the phone anymore.... these will come in handy.

I just looked up the status and the last activity was on October 13th at 3am.... saying it is in Virginia. Starting to wonder if something happened.

Got it in today! Works like a champ. Had to get a new (longer) bottom bolt, and use some washers for spacers, but the little Yaris has a 100 amp alternator in it now.

Here's some pics.... don't know if it's worth doing a write-up/how-to or not....

Nice upgrade! I don't see the pics. I think members would appreciate a write up with pics. I know I would. Thanks.

I dont think there is really a need to upgrade on these cars. Not too many electronics to drain it, and mine usually charged at a steady 14.2-14.3v

There is if you put a stereo in it. Surely I'm not the only one that likes to feel their music.

Maybe, but I have never had a problem with this car draining. Most aftermarket batteries also are sold with larger cca than the factory battery.
