What are some good brands out there and what else do i need to make it run smoothly?

 

Are there any official superchargers released yet? Last I heard, there were all still prototype-ish

 

LMS is the only supercharger for the IS right now, and it's not really even in full production yet. I believe they are waiting on all the parts before offering the kit, but all the R&D is done and several members have it installed.

Blitz also had a supercharger on display at a show, but from what I could find the kit will not be released due to the high cost.

 

ahh thanks
