A decent answer is the alt. out of a '76 TR6. They put out approx 48-53
amps, and are still original equipment (i.e. no one will know you
changed it). Turns out not all Lucas alternators are not created equal
- they improved them over the years. Also if you have an air-pump on
your car and would like to keep it, steer clear of the GM conversion -
it does not fit!
'76 TR6 - CF53954U
Subject: Bosch Alternator Conversion
Anyone remember what years the Ford Fiesta contained the Bosch
alternator that is pretty much a bolt-in fit for a TR6? I believe that
this alternator produces in the range of about 40 Amps. Anyone know of
another application with the same mount design that puts out more
amperage? Thanks for your help.
