I'm currently researching an alternator upgrade for my datsun and I came across the P12 Primera 2.2diesel alternator which is a 110amp unit with the mounting ears in the same position as the Z32 one, and the datsun one. It has a V groove pulley so would need the pulley to be swapped but it's bolted in so shouldn't be a big problem. Looks like the width between the ears is about correct too but I'm waiting on confirmation on that one....

Anyone else knows what fits? I've heard someone use a 350Z one?

There is a write-up here (unfortunately the pictures appear to have disappeared):

But that's more relevant to the Americans, UK might be different but here in Norway we never got any of the infinitis or the big wagons/vans or any other vg powered car, so finding one in the junkyard is near on impossible...

 

I've compared the measurements and the width between the mounting ears on the diesel p12 is the same 81mm as the zx. The distance from behind the forward mounting ear to the center of the pulleys are also the same at 42mm. The diesel pulley is a v groove but they're both bolted on so a pulley swap "should" be an easy swap.

The connector is also the same between the two and in nearly the same location. So this might be a viable option if one needs a 110A alternator.

I'm putting in bigger speakers in mine and a subwoofer next year so I'm thinking of trying this.

That's true, however it is not that difficult to import one from the US.

 

Here is another option (again it will need to be shipped from the US):

and another option mentioned here from the Australian 300ZX site:

I see the z31 people are using the pre 2004 350z 110A alternators as bolt in upgrades also. Some swap the pulley but not needed. So that should work for us also

True, but they're heavy so shipping is a bitch and import tax means it will be as expensive as buying something new here

Don't think I'll ever need 170amps [emoji50]

Spiff did you ever find out what alternative alternators would fit to the Z32 ??

It kept coming back to the early 350z one. 110A. But swap the pulley over and you could use the primera diesel one.

Sorry for the late reply

Thank you. Could you give me the specific primera diesel model and year?

The early P12, 2003 or so I believe? 2.2 diesel

No that's a 80A so would be a downgrade.

2002-2003 primera P12 diesel yd22 engine. 110A
