So we all know that we can do a bolt-on upgrade to the 90amp Maxima alternator, which is a great bump up from the stock 70amp alternator.
But if you have done some upgrades such as dual radiator e-fans, aftermarket sound system, etc.. you might need more than just the 90amp.
Mind you that the 90amp rating is generally at its peak RPM, which is around 5000 rpms. The common drive range is 2-4000.
There are a few other choices for alternators as well;
SATAN and a few others have ran the 2003 Nissan 350Z 110amp alternator (almost a direct bolt in)
I have ran the 1999 Nissan Maxima 125 alternator (requires some modification)
I am sure there are other ones as well.
And a GM 160 amp (mind you, not Nissan)
Well, my 99 Maxima alternator was going out and I knew I had a life time warranty on it with Napa.
So I decided to research other alternatives.
I found that the 2005 Nissan Titan alternator has the highest output of 150amp and requires very little modifications to install it.
Its kinda spendy though, but its well worth it. Especially if you get one that has a life time warranty on it.
The total was around $285.
The alternator as it sits. Its pretty beefy.
The documentation that it came with. Notice that amps by RPM specs. Looks good!!
Stock z31 plug. You may need to put a bigger i-crimp on it.
I made this harness for the ground for the alternator to be a quick unplug.
Notice the pulley has more ribs. Thats okay. You don't need to get a wider belt. The belt I am using is the stock z31 alternator belt.
This is the only modification you need to do (unless you get a different alternator bracket).
This bracket I made is simply an extension for the adjuster. The alternator bracket is the stock z31 one.
All bolted in. It bolts up tight and works great!
