If you take a look at the top front of the block on the passenger side there 
should be an engine code stamped there. I think the code for the 6 cylinder 
prior to 1995 was an AAH code while the 1995 to 1998 or 1999 is an AFC code. 
These two engine codes are 2 valve per cylinder while the later model 6 
cylinders are 5 valve per cylinder engines. The only supercharger kit I've 
heard of is for the 5 valve type.
