I don't know our current capacity, but it's easy to find aftermarket 3.6l alternators that put out 145 amps. So ours should be at least that beefy. FMI, what do you need ~2.6kw for? Not disputing you, and I don't keep up with high zoot sound systems and light packages, but what?Anyone able to find a high output for the 2.8d? Seems like this alternator of ours is specific to the motor.
I saw somewhere GMC van has a 2.8d option and a ambulance package that has a 220 amp alternator. But I couldn't find any other relevant info.
