Yaris T-sport Alternator Upgrade

[Steve Ratcliffe]

Does anyone know where I could get an upgrade alternator for a Yaris T-Sport.

The standard alternator is rated by Toyota at 840 Watts, so I calculate the current output at 14.2 volts to be 59 Amps, which is a little low for my system. I would appreciate any info from anyone who has done this, or anyone who knows of a replacement alternator with a higher output current.

Thanks

Steve.

have you considered upping you Battery size as well, if your going to upgrade or add an aditional alternator ?

I have nearly doubled the storage capacity of the Battery from the standard unit, I am considering one of the dry cell batteries designed for performance audio systems. With the current upgraded Battery, which is one of the VARTA Silver performance ones, the alternator is a little underpowered, with the new system going in the T-Sport I am pretty sure I will need to change the alternator.

Thanks Rahines,
