I will tell the dudes then. I was once a dumb turd too.
Yeah they are different, the series 1 turbos have ceramic turbines and the series 2 have plastic turbines. Means that the series 2 turbos are able to spool up a little faster, but they are weaker cos they are plastic.
If thats all u need to know, then there u go, but if not, the USE THE SEARCH
