I'm gonna replace the alternator now that its payday on my 03 G35 Sedan. The 07-08 model G35's list 150 amp alternator. 03 Sedans list 110 amp alternator. Since I will eventually install a system I was wanting those extra 40 amps if the alternators are interchangeable. I know I have a 6S pulley and I think some list a 7S pulley. All I want to know is if the HR alternator fits fine in a VQ35DE.
