Hi Packa

I replaced my alternator with a Impreza Sports Wagan rated at 90amps "so i was told"

Plus replaced battery with Optima D34 -

0 gauge earth lead
4 - gauge starter
1 - gauge power lead "for stereo"

Hav had no problems at all

thanks guys i will be putting some additional earths in and upgrading the originals hope this stops the dimming lights seems like a bad earth only happened after i disconnected the battery . was using the amp before so shouldnt be that. i am running o guage for amp and earth wires . battery is already a 560 cca .

If the lights are dimming it usually means that the amp draw from your amp is to much for what your alternator is putting out. When the car is running the battery doesnt make any difference, the battery is only for starting the car, the alternator charges all the electrical "stuff " while the motor is running. A cap would help because they store power, so in affect its like having a high amp alternator...

to answer the question,

yes, check a JDM GC8 STI, they have 90amp alternators.

will an alternator out of a EF falcon v8 fit? i think they are very similar in physical size and shape, bolt holes. they are 110A. Would proberly slip under full load though with such a narrow belt though
