Guest Anonymous Posted May 8, 2003 Share Posted May 8, 2003 Got relays on those lights? Might not need a new alt. Quote Link to comment Share on other sites More sharing options...

yo2001 Posted May 8, 2003 Share Posted May 8, 2003 You can run newer model Nissan alternator. I'm running 95 Maxima SE alt. rated @125amp. You would have to convert the external volt regulator to internal and change the pulley. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted May 8, 2003 Share Posted May 8, 2003 Yeah the maxima one is nice. I have an 87 model maxima one, and it is easy to wire up, puts out 90 amps, and has an internal fan, so it just looks cleaner. They bolt right in too. Just have to swap the pulley. A side benefit is I swear my car runs better with it then the stock 60 amp one. Quote Link to comment Share on other sites More sharing options...
Sparky Posted May 8, 2003 Share Posted May 8, 2003 isnt the late 280Z alt. internaly regulated? do you think you would have to change the wiring at all using the max. alt. in a 280Z (or a 240z with 280 wiring.) ? I was thinking of switching to the one wire GM alt. but this sounds interesting. What are your opinions on the GM vs. the max alt.? ?

yo2001 Posted May 8, 2003 Share Posted May 8, 2003 77 was the first year of internal regulator I think. Nissan alt. is probably more expensive than GM unit without a core unit but you don't need no special bracket. So I guess it's all personal reference.

Lockjaw Posted May 8, 2003 Share Posted May 8, 2003 You could get a core one from a Junk yard for cheap. Or just take yours back, its not like the parts place is likely to notice. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted May 8, 2003 Share Posted May 8, 2003 As far as an opinion, what would you rather have, a nissan or GM? I like the maxima one, and I have heard you have to get over 2k in the rpms to energize the GM one. Not to mention you have to come up with some sort of bracket to mount it. The nissan one is a direct bolt in, and I made a little two wire harness to connect the ZX plug to the maxima alternator, and it was good to go. It is a very clean looking unit too. I hate those external fans. Quote Link to comment Share on other sites More sharing options...
z-ya Posted May 8, 2003 Share Posted May 8, 2003 I put a GM one wire 100 amp unit in my 240Z. I didn't really like it. The regulation was not as good as I expected. It was noisy too. I returned it, and now I'm running a 280ZX alternator. Pete Quote Link to comment Share on other sites More sharing options...
