is there a alternator that will fit the L20 but with a internal regulater so i can loop the insides...and run a wire direct to charge??or what alternator could i use that will have the least amount of mods to do...? w/high amprege..

dont know about high amp
but i got an internal reg one off a series one bluebird, goes straight on like all good datto stuff

how can i get a hold on one of those??can i tell my local parts store to get it...what are the specs i tell them??

its a bosch internal regulator alternator from an 83 series 1 bluebird, could get specs from dads tuneup book, but the sheds all locked up

From memory, the Bosch altenator that came on Series One Bluebirds was rated at 55 amps & the one that was fitted to Series Two cars was rated at 60 amps.

look i can contribute actual good info for once

all bluebirds came with internal reg alternators 4 bosch and one lucas

they were(i think these are the codes):
boschUK1-14V40A22t(little t looking thing)
boschUK1-14V45A22t
boschUK1-14V60A22t
boschUK1-14V55A22t
Lucas14ACR-6Dt (55A at 6000rpm)

all of those were fitted to series one or two bluebirds, the higher power bosch ones (45, 55 and 60 amps) were from the sept 83 onwards ones, possibally the series 2 (tune up book doesnt distinguish b/w series 1 and 2)

so i'll just tell my parts store that i want a series one nissan blubird alternator?and it will bolt on my L20 in my 620 pickup..1972?and all i do is run one wire to the battery?

tell them you want a bosch 60 amp internal reg alternator from a series 2(coz they have the bigger power ones) bluebird

and it should bolt straight on, the only difference in alt brackets is that some have 3 bolts to hold them to the block and some have 2, no difference in where the alt actually connects
