Nismo280zEd Posted August 10, 2003 Share Posted August 10, 2003 so i was reading the "how to modify your Nissan/Datsun engine" book today.. and i read that the late model Z cars altenators can easily be put into an early Z car. So what are the down sides of puting an 83zx altenator into a 78 280z? the book said early z car altenators put out between 35-60 amps and the late ZX puts out 45-80 amps Quote Link to comment Share on other sites More sharing options...
zcarnut Posted August 12, 2003 Share Posted August 12, 2003 Don't believe everything you read... Your '78 alternator is rated at 60 amps. The 280ZX alternator is also rated for 60 amps. The 280ZXT (turbo) alternator is rated at 70 amps because of the electric radiator fan. This alternator can be used in your 280Z with no mods. The 300ZX (Z31) alternators are rated at 70 amps as well, but you have to swap the serpentine pulley with an earlier V-belt one. However, this alternator will bolt right up to your present L-series engine alternator mount. The alternator to get are the V6 Maxima alternators which were rated for 90 amps (starting in the late 1980's) and 110 amps (starting in the mid 1990's). Again, these require the pulley swap. The output terminal of these alternators is later(8mm) than the earlier alternators (6mm) so you will have to modify your engine wiring harness.
