what options are available for an alternator upgrade on a diesel hilux?
is it possible to use a gq diesel alternator which i have been told has a vacume pump built in, is this true?
what is involved in setting up a dual alterntor, dual battery system?
thanks.

the way i would do it . vacuum pu7mp off a chevy v8 diesal[all they are good for]then u fit bosch 85 amp alt delta wound to 125amp. yes a bit of fabrication involved but results are worth it .only costs 85 to over haul if it fails.vacuum pump is belt driven.

I heard somewhere that the surf alternators are 90amp due to all the elctrics they have - can anyone confirm this? as I am looking at upgrading my hilux alternator which i believe is 70amp?

The hilux alternators respond well to a rewind Im told.
100+ amps to be had.
