Alternator upgrade question

[NY " Z "]

Hey guys

I'm looking to upgrade my 240Z 40 amp alternator to the 60 amp from the

280ZX

I picked up 1983 280zx non turbo aftermarket alt.from the local auto parts

store. but the alternator wouldn't fit the mounting bracket.

Is there a certain year alternator that would fit?

Do I need to modify the mounting bracket?

Any help would be grateful.

Thanks.

Just did same mod, had no problems with the fit

I recently helped a friend through an alternator upgrade. Four trips to the parts store is what it took. It seems that the rebuilder incorrectly identified or boxed a batch. The correct one will fit. Oddly (maybe not) the retailer did not want the incorrect units back..... Anyone need a Hitachi "deep cycle" for their boat or RV? Nice $250.00 unit if someone could determine the application.

Hey guys

John thanks for the reply your probably right. I'm going to return the the alternator and a friend recommended an alternator shop that could upgrade the amps on the one I have.

Would this be a better way to go?

Any comments would be appreciated.

more so than amp upgrading the best beni I think is the internal reg!.

Another option is to install a 105 Amp alternator from Z Specialties. I will tell you that this is one of the best mods I have ever done to my car. Why I waited so long to do this heaven only knows. Everything seems to work better. Lights are brighter but not overly so. My little 35 watt stereo sounds better and the car just seems to run better and I haven’t a clue why unless its just me. I turned every electrical thing on, lights, PIAA fogs, stereo, rear-defroster, blower, wipers, signals, and at idle there was not a blip…. On my original alt, if you had two things on you’d be lucky to get the wipers to creep across the windshield…. And at idle, forget it… it would take five seconds for a swipe of the wipers.

The Z Specialties alt is a breeze to install. It’s a direct plug and play operation. You use the same pulley, bracket, and belt. Wiring is simple and straightforward. The instructions that come with it are fool-proof. The stock Voltage Regulator comes out. I opted to use an additional 8 gauge wire directly to the battery in addition to the stock wire. Testing the alt, it was putting out 14.8 volts to the battery. I think this may be a tad high, not sure. I also took some pictures of the install but believe me this is a simple, no-brainer operation. Strongly recommended…..

You might to try this option too. I used a 91 Maxima alt, rock steady 14+ volts at idle. Easy to get at any parts store and cheap. The trade off is that it's not a plug and play. I took me about 90 min to set it up, this is NOT a PhD required swap. Follow this link to see more detail. http://www.zcar.com/forums/read.php?f=1&i=565207&t=565205#reply_565207

And do upgrade our wire to 8 gauge like ZIII recommends. Or your stock wire might melt down.
