I wanted a new alternator so I went with the one priced in the middle on RockAuto. I painted it silver to match the rest of the engine and to give it a protective coating.
Looking into how similar the alternators are for the RX7 and Mx6. Looks like 10amps different and they share the same family housing the Mitsubishi IF.
