Back in the day I had a Hyundai Terracan Alt ( vacuum pump attached in the back ) on Tencha .. those are 120amps alt .. if you don't need the vacuum you are good to any other alt ..
I presume yours is 12V? Your sig line mentions conversion, what year motor is yours? Do you know?
That alternator from ozautoelectric is really good. I have one.
pulleys included.
