Altenators

[nugget400hp]

Can anybody tell me if rb20det and rb25det alternators are the same? I'm looking at running one on my rb30et as I'm running au twin thermos, twin 044s, carter pump etc so I might need the extra charge.

Cheers

cheers, i know they all bolt on, i just wondered if the rb20 one is the same as b25 (as its better than the rb30) and a bloke has offered me an rb20det one.

[nugget400hp]

I posted up a thread not long ago as well... no one responded...

but I've recently bought a RB25DET alternator for my RB20DET with the plug as well.. I'm planning to install it this weekend...

RB20DET / 70amps

RB25DET / 80amps

RB30ET / 60amps

The Nissan US quest minivans (same as the oldsmobile) uses a 110amp (also get 125amp), I stuck that on for my S14RB for all the added voltage load from the dual 20a radiator fans, meth, fuel pump ectr. Cost me $160us for a full recon one shipped from the US to africa,

like so:

but then you need to fabricate a bracket for it to fit.

has anoyone fitted the 125amp alternator from the quest before??

I suspect the Neo ones are 85A. I remember being happy about the size of it when I did the transplant (just because MORE is always better) but not the actual number.

im currently doing the swap, my old alternator wasnt up to the job, couldnt even get it above 13while running, dont think the ignition system, ecu and twin thermos help, let alone the relocated battery might of played its part also. will let you guys know how it goes after the swap

[AngryRB]

sort of related , my volts on start up are up at 15, and the battery lights on, this could be due to changing from a gtst dash to a gtr dash but even the tuner mentioned it was a bit high,

so do i need to replace the alternator and problem solved?

[StevenCJR31]

may not have to swap out the alternator. . could be a faulty/ non functioning voltage regulator
