rockauto lists your alt as the ad230

i came across this; it says no mods required.

sorry, its very misleading. i found this on a different part of the site, you need a u bracket to mount the 244 on these engines and they dont sell just the bracket that i saw. it doesnt look like it would be too hard to make your self though

if anyone knows of a car that has a bigger alt than mine that I can upgrade to please let me know in a message, I dont have time to hunt around and I need to upgrade mine pretty soon.

thanks

What cars can i grab a more high powered alternator from for a 01bonneville ssei

you can get this bracket to put a ad 244 on it. search for ad 244 to find lowest price or applications for jy.
