I appreciate you looking out and all but i was told that there is no supercharger currently available for my year truck. Oh well guess i will be re building with high performance parts.

It depends on if you have drive by wire or cable throttle. 2002 was the year they changed mid year. 2002 DBW can use a blower for 2003 trucks, which is what I used on my 02 Denali.

Thanks now how the hell do i find out what i have ? Is it obvious?
They look very different. Go to RockAuto and look at the throttle body for the 2003 and compare it to the throttle body for 2001 and then see what you have.

THANKS BRO.
Also the drive by cable has an actual throttle cable going to the TB and the DBW just has an electrical connection at the TB.

yeah i am asked out my throttle is definitely electronic. I remember now a few years back i was cleaning the throttle body and had to turn the ignition to on position just to get the little wing looking door inside to open.
You should be set then. You can check your RPO codes inside your glovebox and look for KUP which is Electronic Throttle Control, just to be sure. Then you can talk to Blackbear Performance and they will help you order a blower, they helped me with the correct one.

Yep. You have DBW so a blower for an 03 will work. Just like mine.

i dont doubt this kit will do what it claims, for a while anyway. but a lot of these kits take some liberties in the application.
as far as fitment i would worry about it being real close to the a/c lines, make sure it fits with either radiator 28"/32", most need to have electric fan conversion, the long lengths of silicone hose for charge pipes any rubbing and they'll cut through. the downpipes look like they wont even make it out of the engine compartment? cheap wastegates run the risk of not opening to control boost, same with the bov after wot. no maf provision, not that its necessarily needed but just more tuning work to do. spark plug access/addition wire length needed? driver side looks like it puts the turbo right into the main harness that jumps over to the engine. cast manifolds are a toss up, most of the ebay manifolds i hear about crack pretty easily - these need to support the turbo and any movement at 1800+ degrees.
its not that this wont work as a twin turbo kit but if you need to spend another grand or two to relocate everything to make it work, youre not saving a whole lot.
