Dean's right, I'm looking for a class that will allow me to up my boost, and swap the turbo/IC.  At least in NESP I can instally those IC hoses I've got. 
On the other hand, running in ESP w/ race tires might be a blast!  But then I'd get beat up on by Lucas instead of Dean. 

  At least I could try to represent for the Suby crowd against all those F-Body and 'Stang guys! 
Those ESP rules regarding brakes: where does it say you can replace the rotors and calipers?  I see a lot of stuff about lines, etc, but can I toss a BBK on there or not?
