alero irs already installed,  
moddified wrx coilover suspension for back up to the air ride,

manual trans,  
colbalt supercharger setup w/ 3.1 pulley,  
have a 2.7 pulley and bigger injectors for later down the road,  
factory sunroof out of coupe(sedan never came with one. 
there are other things i just cant think of now. this build will be more complex than most others but will still appear factory and lay on the ground. even on the inside it will sport mostly factory parts with carbon fiber accent and painted peice hear or there. here are a couple pics of before the major changes that are taking place.
