Alternator

[RB20_ZED]

my Rb20 alternator is going bad...

ive heard from a lot of ppl that they "think" rb20/25/26 use the same alternator but i wanna know if anyone knows "for sure". like can i go get any one of these and have it fit my rb20 with plugs, belts, bolts and whatever else?

also - anyone got any suggestions for alternator swaps that will provide more amps? (that are safe to use with standard wiring etc)

and i remembering reading about someone buying a brand new bosch(?) alternator that fit perfectly (cant find the thread now) - anyone know the part number for this is?

thanks.

I currently have an R33 alternator (90A) on my 89 R32 GTR. Bolted straight up. I also currently have an R32 GTR alternator on the RB30E in an 87 R31 Silhouette. The GTR alternator replaced an RB20DET alternator I had on the R31 for a long time (bearings have gone). Again, bolted straight up.

That's not say every alternator is directly interchangeable. For example some Oz spec R31's came with a Bosch alternator and the connection is different for those compared with Jap spec alternators (eg Hitachi).

thanks man - is the r32 gtr alternator rated at 90A also?

what are rb20 alternators rated at?

80A from memory.

My experiences with my dad's ceffy, which has an RB20DET as well.
