Anyone upgrade there alternator??
Ive got a '91 22re Id like to upgrade the stock unit but dont know if the stock is rebuildable with more amperage output or if there is an aftermarket that will bolt up.
Any help??

 

nevermind....found one!

 

Sorry about being late, but I got mine at www.mralternator.com. It is normal Nippondenso case like my OEM, but 140amp.

 

www.hoalternators.com

Standard toyota case with 190 amper output. I LOVE mine. They now have a 200ampre unit that is a direct bolt up unit.

 

Kool!
Doesnt hurt to shop around I suppose?
Will I have to make any other mods going to a 190 or higher amp unit?
I understand how they work but am not familiar with the computer goodies in the newer vehicles and Id really hate to burn something up that will cost even more $$$.
Thanks for the help guys!!

 

what about for my truck? its an 85 22r with the carb and no options other than heater

i think my stock alt is like 40 amp

 

Anyone have experience with www.MECHMAN.com . I was searching, but no1 has mentioned buying anything from there.

 

I dont know if your engine has a braket or room for the 3vze's alternator. I'd bet a 6pack that the 3vze and 22re alternators are interchangable though. And if so, then yes, you can run the same alt I'm speaking of.


Well you should upgrade your big 3. But you should be fine with just an upgrade on the charging wire. I have 1/0 run from the alt's positive charging post to the battery. I dont trust the stock unit to carry that much amperage.

The big three is basically upgrading your battery's ground to chassis, block, and frame, and finally running a larger charging wire to the battery.

I have used nothing but 1/0ga.

 

mine does have a slider upper bracket on their that has a half moon shaped adjustment while the lower bolt is a fixed pivot point..... also i think maybe its possible for the 22r alternator to be interchangeable with the 22re? or no?

 

At what point do you need to upgrade your alternator? The only thing that I have thats really drawing a lot of power is me FAL fan

 

hey AzStorm,
I have an 89 22RE and i just bought and new alternator but i didn't really feel like spending $400 for a 140 amp so i just found out the the automatic alty's are 90 amps and the bolt right up and they are the same price, its alot better than the stop 60 amp, but i would way rather have a 140 or bigger if i had the money
