I don't know if this ports over to Sols, but my best friend's dad is addicted to buying $300-$500 minivans (TranSports, Luminas, Caravans, etc.) and fixing them up and selling them for like $2000 more each. His Lumina alternator died like a million times, so he replaced it with a heavy duty Pontiac one, and then like half of the car's problems went away.
So....does Honda make any heavy duty alternators? They can probably be adapted to fit.
