The first steps are to purchase a 79-83 280zx or a non-turbo or 81-83 turbo alternator. The non-turbo alternators are 60amps and the turbo model is 70 amps.
Purchase the part above from motorsport auto. Cost about 30 bucks. This parts allows the new alternator to perform right. Remove the External regualtor and plug this unit in.
They are the same size, thus the larger amp/internally regulated alternator will fit. Bolt the new alterntor in and adjust the belt, and your set.
