You sir have a lq4 no lq9 was made I'm that year they started producing them late 2002 for the 2003 models like escalades Denali and Silverado Ss .anyways ls6 is the superior intake that gm made for a 3bolt tb there so many variables of intake u can use .my suggestion for a turbo street build ls9 head gasket arp head stud ls6 intake high volume gas pump and 60lbs injector lq4 motors compression are good for boost in less u but a cheap 4.8 that loves boost .proven 1000 hp on stock bottom with a ls9 head gasket and arp head studs but that's just my opinion
