it would be easier to do something with the alt. you can reduce the size of the pulley. or change to the newer style alt, that has better idle output. i would have to do the research again but there is one that is just going to the yard or getting one at the stare for a different car and minimal mods to make it work

I'd be interested in learning more. Where do I start looking?

CS130, CS130D, AD230 AD244 High Output Alternator Upgrade and Parts

that was quick!
But, it isn't for our alternators. Ours is already a 140amp, these are upgrades for the smaller 100-105amps.

ours are either cs130 or 144, the ad244 or 230 even junk yard ones are said to test at 100+A. the cs they say is about 50a at idle

I dont know about yours, but my alternator doesn't look anything like that. Plus the mounting holes on the case are way different...

This is the alternator for my car

stock alt for 98 bonnie is cs-144. if you want to get one of the 244'* from the junk yard or new, you just need the bracket i posted, possibly a different belt. the belt i dont know seems back and forth

Ok, why does it look different than the pics in the link you posted? Im not doubting you, just trying to figure out the discrepancies.
