[Supras] MR2 100amp Alternator in 92T --- NOT a drop-in replacement??.....

[B A]

Yeah, alternators seem to either be lemons and go bad quickly, or people can
go 10-15 years without changing one.  I know the one that died in my 92T was
the original stock alt, so it at least gave good long service.

As per my supraforums reply from a few minutes ago, I am going to replace
that PVC line (apparently it's not even an oil line, just air) with new,
more flexible 3/4" PVC or braided stainless steel.  And in a slightly longer
length too, so I can route it *around* the alternator (ie to the outside of
it), instead of down behind the alternator where it's cramped between the
alt and the engine behind it.  Hopefully this does the trick.

Ordinarily I'd have just gotten the stocker 80A replacement, but with a
newly arrived 250W Infinity Basslink II and Infinity BassLink 4sc
supplemental 50x4 W amp, along with a power Gentex chromatic mirror, TRD
boost gauge, high-end Alpine CD player, AVC-R boost controller, plus
upgraded headlights, etc..... I didn't want to run the risk of getting into
that situation where at idle the headlights go dim, etc. when your stereo is
playing loud, etc.  Hopefully those extra 20 amps will help in that
regard...

Cheers,
Brian
