difference between mini and micro?

I see this place has a section for a mini sprint and micro sprint. What would those differences be? And where would be good to go to find info on 600 gsxr engines. I did a search on googles and didnt find much other than a bunch of nimrods wanting to show you how to change the oil
 
Seems like a niche market . Vance and hines . Suzuki was not listed .
Thats the big money guys header, i'm a schoenfeld guy. Ive got a friend who is going to let us put our motor in his car and i'm trying to get everything together. Not spent a day in my life on a motorcycle nor wrenched on micro's so really lacking on this stuff
