I'm guessing that different models will have different alternators. If you compare what electrics are on a base model to those on as SEL they are going to require a bigger battery and alternator I would have thought.
Yeah... That kinda sucks. I know (I looked up a long time ago) that Lexus IS 220D stock alternator does about 130A (my previous car, an Audi A3 Sportback 1.9 TDI had 140A; 10A more then my Lexus!).
I don't know what your alternator does. Anyways it's hard to get this kind information. I will make an enquiry at the garage next month, cause I need to bring it in anyways.
Would be nice to have a more powerful alternator for my (power)needs.
I already contacted a few companies, but none have answered me so far.
