What would you guys reccomend for a high output alternator? Is this something I would be able to install myself, or would I need to get it, then find a mechanic to install it for me?

 

What are "bolt on" specs if any for a 93 legacy wagon? Just need that to start the search!

you should search for a post you posted before. I gave specs on the alternator I'm using

This is probably the least amount of modifications you're going to have to do, simply because most if not all the HO alternator applications are going to use the new casing design, vs. the older style.

 

You could try taking your alternator or an older one to a shop to see if they can rewind it and increase its output.
