the only alternator upgrade you will most likely find in the 2nd gen section is people upgrading from the 117amp alternator to the 136amp. there was a thread about installing a 2nd alternator but it has a v-belt so i am not sure what i came off of. no matter what you do it is going to cost you a pretty penny
