84z31 Posted December 18, 2005 Share Posted December 18, 2005 this is on an 84 300zx non turbo so far. okay i have read all about the maxima swap. but i want more then 90 amps. so my question today is the following. has anyone had there stock unit rewound for over 100 amps? i am considering doing that if the price is right. there is a local guy i have used to work on chevy alternators i used in my old toyota truck. he converted them to self excite so all you had to hook up was the battery cable. i am also thinking about going the chevy alternator route as well. i can buy one of those and have 105 amps out of the box for $100. and then another $40 for my alternator guy to rework the regulator. i think i would mount it in the air conditioning bracket. i will have to fabricate a bracket to hook it to the air conditioning bracket but it would be alright. the chevy alternator puts out 70 amps at idle. that is the main reason i want to use it. and the fact it puts out more power. i swapped a supra motor into my toyota truck and have repeatedly reved it over 5500 rpm. the alternator handled it fine and i never had any problems. the factory alternator in my car is having trouble when i have just the lights and rear defroster on. it brings my battery down to about 13 volts. so what are your opinions?

mc Posted December 19, 2005 Share Posted December 19, 2005 I believe the vg30 Quest minivan has a alternator out put of over 100. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted December 19, 2005 Share Posted December 19, 2005 Most likely your alternator is on its way out if it can't handle the lights and defroster. I would think the Maxima alternator would be more than enough. Are you planning on running a pretty large audio system? If not, I wouldn't think you'd need more than the Maxima alt.

84z31 Posted December 19, 2005 Author Share Posted December 19, 2005 my sterio alone is worth 1500 watts. plus head lights and fog lights. and the stock computer system. Quote Link to comment Share on other sites More sharing options...
84z31 Posted December 19, 2005 Author Share Posted December 19, 2005 i looked up the quest alternator. its good for 110 amps. that might be what i'm looking for! thanks! Quote Link to comment Share on other sites More sharing options...
mtcookson Posted December 19, 2005 Share Posted December 19, 2005 my sterio alone is worth 1500 watts. plus head lights and fog lights. and the stock computer system. wow... yeah, that'd be roughly 107 amps @ 14 volts. definitely time for an upgrade.

84z31 Posted December 19, 2005 Author Share Posted December 19, 2005 i guess that would be at peak power too. which i would never get to. i'd be deaf. but i do plan to add electic fans so this is a very vital upgrade! Quote Link to comment Share on other sites More sharing options...
mtcookson Posted December 19, 2005 Share Posted December 19, 2005 yeah, peak power would be very hard to get to. i wonder what those things normall run at, probably not all that much actually. Quote Link to comment Share on other sites More sharing options...
84z31 Posted December 19, 2005 Author Share Posted December 19, 2005 i think the numbers are more of a WOW factor!!! i usually just turn my pioneer head unit up to 20. Quote Link to comment Share on other sites More sharing options...
EZ-E Posted December 20, 2005 Share Posted December 20, 2005 The newer maximax, above I believe 95 or something like that have 125 amp alternators but I dont believe those will bolt up. That is where you will run into a problem. Quote Link to comment Share on other sites More sharing options...
84z31 Posted December 31, 2005 Author Share Posted December 31, 2005 well i finally had the time to get to the parts store. the quest alternator will not swap in. it has a different bolt pattern and wire connectors. not that has stopped me before. but i think i'd rather put a chevy one wire alternator in.

Guest Jason84NA-T Posted December 31, 2005 Share Posted December 31, 2005 well i finally had the time to get to the parts store. the quest alternator will not swap in. it has a different bolt pattern and wire connectors. not that has stopped me before. but i think i'd rather put a chevy one wire alternator in. I know of one person that has installed the quest alt, and I recall he said it was a pain. My maxima alt works great with everything on and the stereo CRANKED. If comparing stock alternators you should look at the efficiency curves of the stock alts and consider overdriving the alternator with a smaller pulley to get amps up at idle. The maxima is 90 amps peak compared to stock 70 amps, but it also delivers about 11-15 amps more at 3000rpm(alt, not engine). It sounds like you're going for something serious though, you might want to take a look at this: http://www.zena.net/htdocs/alternators/AutoSound.shtml Quote Link to comment Share on other sites More sharing options...
84z31 Posted December 31, 2005 Author Share Posted December 31, 2005 well i decided i didn't like the 12" subs and 1200 watt amp. i traded my brother them for his 10" pioneer (400watt) in a band pass, with a pioneer 300 watt amp. it sounds much better. that sony stuff just sucks compared to pioneer. anyway, i think i'll be drawing less so i'm going to get the maxima alternator. the only other addition will be my electric fan. i should have the wiring harness finished today. so i can test it out and see if it kills my alternator the rest of the way. i'm holding out until its completely dead.

Guest Jason84NA-T Posted January 2, 2006 Share Posted January 2, 2006 so i can test it out and see if it kills my alternator the rest of the way. i'm holding out until its completely dead. That sounds like a good way to get stuck on the side of the road at 3AM. Ask me how I know. Quote Link to comment Share on other sites More sharing options...
