I have a chance to buy a 2000 Z24 with a blown engine and looking at the pictures my buddy sent me I see that there is a supercharger bolted to the front of this thing.  Who made or used to make a supercharger kit for these cars? or is it a homemade job?  I haven't seen it in person so I don't have any details.
 
 
Well I guess GM made one at least  lol
 
GM made a supercharger kit for 00-02 Jbodies ( part # 12498660 ).  Very well put together kit.

After looking around I'm 99% positive that is the GM kit, the brackets are the same, the supercharger is the same, air filter tube is the same.   They don't want a lot for this car because they ran it low on oil, I def think I'm going to try and save this Z

Do it^^, and if you decide you don't want the S/C kit, let me know I got a good home for it in my driveway. 
 
 
 
look at the baby supercharger, d'awwwwwwwww!!!!
haha jk, but yeah its rare to find a factory supercharged Z (as in factory kit and not put together like the rest of us), that would be a fun restoration project!
do you have any other pictures? outside, inside, etc
