For anyone that wants just a little more amperage than the 110 amps the 97 and earlier Quests alternator have... I have confirmed the 99-02 Quest alternator fits with the same modifications to the earlier alternator. Its rated at 125 amps.

I don't think there is a difference in the size between the older Quest alts and the newer one. I did have some issues with it hitting the pipe under the intake manifold and only have about 3/4" to 1" of adjustment. That put the pulley and belt close to the radiator hose. I pulled the little tube up a little and got about 1 1/2" of adjustment. I haven't noticed any ill effects from this as of yet. I will update if anything weird starts happening.

I didn't try the pulley off of the KA alternator. It just looked like it would have the same issue. The Quest pulley worked the same way. I just used the ribs at the rear of the pulley. I ended up needing a 31.5" belt also.

I also replaced my battery terminals and battery cables while I was replacing the alt. I ran 1/0 guage wires in place of the ground wires and ran a new 1/0 guage wire directly from the alternator to the battery. Basically did the Big 3 upgrade.

This upgrade is 100 times easier to do if you remove your fan and fan shroud. I tried to do it without removing all of that, but after looking at it for about half an hour I just took it out.

I also wanted to throw out a huge THANKS! to the people that did the writes up and provided the pictures.
