A good friend of my family got a 2009 corolla alternator in and I was wondering would it be possible to fit this on my tc? I have the factory 100A alt but I need a bigger one for car audio. It's alot larger in amperage and a little bigger in size, it seems to be set up the same way though. Anyone have experience in Alts? Specifically for the tc?

 

No, a regular corolla doesn't have the 2AZ-FE engine. Even the XRS is still slightly diff but closer.

 

You can fab a bracket if necessary. People run sbc alternators on jeep 4.0s or RX7 alternators on a SBC. You can mix and match alternators. Just have to align the pulley/belt and match the amperage to the current requirement.
