Default High output alternator question

I have a 97 2.4l hardbody and I'm putting in subs and all that but I was wondering if anyone knew where to buy a high output alternator that bolts right up or if I would have to run 2 alternators if so any tips. Any help would be greatly appreciated.

You’ve got a couple options. If 125 amps is enough current for you, you can swap a Nissan Quest alternator. http://www.infamousnissan.com/forum/...ead.php?t=5837

Mean Green has a 180 amp alternator, but the only guy I know that has tried one had a horrible experience and ended up wasting time and money. Based on his experience I would not recommend bothering with this option. http://www.infamousnissan.com/forum/...ad.php?t=36173

If you need more than the quest alternator can provide you can blaze a new trail and try using a higher output Nissan Maxima alternator. Some of them are 150-200 amps. You’d have to do some modifications to make it work.

There is also a company that basically uses a GM alternator that is adapted to fit the Nissan, but I’m not sure who they are, it’s been a while since I’ve seen that mentioned.

Let me ask a buddy. One of my buddies is in the competition audio scene. He suggested an alternator to me once after I mentioned mean green. He laughed at mean green at said he prefers something with some oomph and reliability. I'll see if I can get some info from him.

Rugged Rocks has one, 180 amp but it says it's for the V6:

I've run the quest alternator with 2 amps a 200 x 2 and a 150 x 2 with no problems, no headlight dimming.

Singer Alternators. Looks like they are built to order. Might be way more than you need. This is info from a guy who builds crazy stuff to the point where it will bulge sheet metal and blow out windows. My buddy does highly recommend them.

There is a problem with the high output alternators. they can pump out some serious juice, but the heat dissipation can not be improved with the stock case and location. the increased heat fries the electronics.

Heat is generally inefficiency in electronics.

That's why companies that advertise high outputs using the stock case should be avoided, you can't rewind the alternator ( or do what ever they do within the stock small case) and expect it to last.


When I did the high output alternator in my former 87 way back, I used an alternator from Wrangler Power Products, it was a large GM case, I had it optioned with dual outputs so I would not need a battery isolator (was going to run dual batteries but never installed the second one), it came with a adapter to mount it to the stock location and a wiring harness adapter. I also had it made with an external voltage regulator. Cost me about $500 jobber price but that was over 25 years ago.

I would also strongly suggest adding a second battery to your system. I did it with mine years ago and saw and heard a huge difference in my system. With the stock alternator it eliminated the light flicker/dimming of headlights and dash lights at night with the bass.
