i have basically have that same car good luck, the highest amperage i could find for my 94 626 2.0 was 180a. i would check out this new place i found search google for daves dc electric they make custom alts.
alterstart has them to but i wouldnt buy from them its where i got mine and had problems right away sent it back got it rebuilt now it puts out 180a and works solid.
i would get an iraggi with the lifetime warrenty i think that will come out to be like 550 but its worth it if you ever buy another car and stuff too.
