Alternator Rating Amps

[Des]

ok people i have a ae82 seca and I'm sucking to much current what does the standand 4a-fc alternator put out amps wise

[towe001]

The 4a-fc alternator is around 60-70 amps. Generally the alternator from an efi engine puts out more amps. If your not worried about modding mounting points the alternator from the vs commodore is around the 90 amp mark.

Score! Ive noticed with my silvia when I stop the engine at night with the headlights on, they'll get brighter just as you turn the key off (while the engines still turning and altenator still charging) and then die down again as the engine slows to a halt. So the EFI system as a whole must drain a fair amount of power.

 

Noticed much difference with the 90 amper?
