hi was trying to find 100 - 120 amp alternator for mates 1600 rally car , motors a l18

anyone know of anything that fits or close to or we have heard of the standard alternators being rebuild for higher output but not sure who does it

mates asked a couple of auto elecs but they werent much of a help

cheers wayne

Biggest one I have seen that came standard on a L series was one of an L28, was something like 60 amps.

I'm assuming your mate will need this to run some big spotties or foggies?

My brothers friend had 4 hella's setup on a c210 skyline, and I'm pretty sure it had a 120amp alternator, I'll ask him to see if he knows what car it came off.

Shouldn't be to hard a task to find one, as I think some commodores also run the basic bosch external reg ones, and they pretty much all fit and/or are interchangeable.

If you are talking about Jeff's car it had an 80 amp unit. Based on his calculations this was more then adequate to run his 2 x rallye 2000's and the 4 built in unit which were 80/120 & 140's.

Apparently the KA24E's came with a 80 amp alternator, so get hunting for one of those. From reports they are easy to adapt to a L series, minor modding of the lower mount.

They came out in U13 bluebirds and a few others here in aus.

thanks fellas ill let my mate know and we can start looking for one

Wayne I've been looking for a similar big output alternator and a good/reliable one is a Miitsubishi off a early E series Falcon. These are around 80 amps and dont f##k up. The 120 amp job off late Falcons are Bosch and have some issues with reliability. I'll be fitting a Mitsub to my Yellow Stanza. OMD

Hey OMD,
My alternator is from a falcon.. but i dunno what amp's it is :S
how do i tell.. is it marked on the alternator somewhere?

cheers,
Stephen.

Hi Stephen Most Falcon alts are Bosch look on the rear and you'll see a black or silver box-this is the internal regulator and reveals that its a Bosch one [google and get a pick or checkout evilbay for a pic].The Mitsubs are physically small and do not have the internal regulator showing on the back. My informants from the Ford proving ground report that the Mitsub is practically bullet proff while the bosch one has reliability problems but was a cheaper buy for Ford !!Also the #and output is stamped on the central casing it'll probably be covered in crap Cheers OMD

OMD,
i have taken the alt. off the motor and i still can't see a amp's stampd any where.
it has the black boxes and bosch stamped on the alt.!!
all i found was a number,
9945 - 41056 ??
(14V3)

i dunno !! lol

Cheers,
Stephen.

EDIT: googled numbers - possibly 80Amp !! yay !! i might have to bench test it ??

hi guys

mate found a sparky who told him to try 98 model patrol , apparently 120 amps

will be hopefully mounting it up to tomorrrow

hi guys

my mate picked up the alternator today its 100 amp not 120 , off late model patrol 4.2 turbo deisel , the one with single pulley and no vaccum pump

his original alternator bracket had been modified slightly previously but fitting the patrol alternator was the easiest thing that hes modified on the car

Hey Wayne thanks for updating the thread, good information to know!

thats a great tip, thanks mate. And the good thing is there is shit loads of that model around so getting your hands on one shouldn't be too hard.
