Alternating A Alternator

[FLYSKYCHICK]

hey guys... basically my alternator has just died in the bumm and i was in the middle of replacing it. but i could only get my hands on a rb30 alternator at the time so i grabbed it. was cheap anywayz... was only $20 so cant go wrong anywayz...

prob is can you alternate... a alternator to fit on a rb20 thats off a rb30 ???

because the plugs are different.

if so can someone please help me with a diagram or paint brush diagram or make one up or help us out somehow, i dont mind cutting and rewiring if i have to. just need to get my baby up and running again...

unless someone wants to sell me a rb20 alternator...

RB20 R31 elternator... mine died last night and now car doesnt start...

also interesting question does it affect the fuel pump when the alternator is stuffed because the car starting making weird fuel starving noises like verrmmm verrmmm bump bump burrrppp its like wtf... but only at low RPM...

had to keep RPM up so car doesnt stall and as soon as i remove the battery car dies its like the battery has enuff charge to keep engine running... i dun get it...

PLEASE help or sell me a R31 RB20 alternator...

bastards why did they have to change the plugs ???

There's information regarding nearly all of the RB alternators. Also download the Excel spreadsheet that's there and it'll tell you what alternators will be compatible with the one you're currently using.

Doing a search for compatible alternators for my rb20 and came across the link above in a few threads and forums, but seems to be down.

does anyone have the excel spreadsheet referenced above?

I have an r31 alternator for sale. it has the bigger 2 pin plug. You can rewire the plug you have, any good auto electrican will do it.

So you have a r33 gtr with an rb20....interesting. anyways on a different topic. My rb20 one died a 33 one was a straight fit, i have a f**ked rb20 alternator if you cant find one rebuild your screwed one. you are obviously smart enough to pull one out so take it to an auto eleccy and he will hook you up

I recently replaced my alternator on my RB30 there are a few things you can check. i wouldn't rewire it, see if the regulators are the same fit, if they are just swap them.

as for fitting an RB30 alt to an RB20, check the part numbers first, they could be the exact same, if they're different, check the amp rating. as long as its not less then the stock one on your RB20 it should be fine.
