i'm looking to upgrade the alternator in my sierra
what alternators have people used?
and how have they fitted them?

Cheers

You need the alternator out of the EF/EL Falcon. Make sure it is the 110A one as that one is easier to fit than the 100A one. It is almost a straight fit as far as I know (not actually fitted one YET)

Any idea how much bigger the falco alternator is? Obviously my engine bay is a little different but I do know that it is pretty tight in that area. Clutch cable, steering shaft, rad hoses. I'm sure i've heard of this being done before but jeez, it must be a bastard to work on.

I don't think they are too much bigger at all

I've done it Damo. Its a piece of piss. Its on my old 1.3 in the green one if you want to have a look. It fitted in mine with the vitara power steering and everything quite easily. I want to swap it onto my 1.6 now but I haven't been able to find a multi v pulley to replace the single v one on the falcon unit. Guess I shouldn't have ditched the original multi v one when I put it on the 1.3.

Cool i'll have to have a look at it. What diameter is the pulley you need? I'm pretty sure I have a multi rib pulley that might work.

[Scrawny]

I have a pulley that might work too

Thanks boys. I'll strip the existing pulley off and get some measurements. The problem isn't so much the pulley diameter but the depth the centre shaft sits into the alternator case before it hits the bearing.

[Mike]

is there any other alternator that works i've tried a few wreckers down here and none of them had el/ef ones

[royce]

some lasers as well

but if you cant find a falcon alternator your gunna be in trouble getting anythign else

[Mike]

every wrecker i rang said they might have something similar but i've got nothing to compare it too i found one place that had one for like 200bucks
how many amp alternator would i need
how many amps is the standard one?

[Scrawny]

Standard is a little less than 45A so anything has to be better

I think the Falco one is used as it fits with minimal mods

[lump_a_charcoal]

There are always some on ebay...

[Mike]

there is a brand new one on ebay for $297
ill have to see how many amp the one in my cortina is and maybe see if i can use that
