Yeah but where are you going to find a whole new kit? I mean when was the last one made 12 years ago?
I found mine on Craigslist in Arizona 4 years ago. It was complete except for fuel lines, some hoses, and some of the bolts that came with the original kit. Otherwise, it was all there.
Honestly, man, I'd say that is worth about $500-600, and that's it. I paid $1500 for mine, and it was a complete kit.
Here's what it's missing:
Belt
Hoses to reroute the heater core and water pump through the back of the Whipple (there are two ports by the plate that the throttle body bolts to).
The tensioner pulley and bracket (that would be tough to find, don't know what the tensioner is off of. I could send you pics of mine, but it's not the stock GM one you have)
The main snout bracket.
Pieces of the intake tubing. It isn't supposed to be like that.
Here's a reference pic, you can see the brackets and tubing that he's missing. As for the cooling system hoses, I have a feeling they're stock parts, just maybe from a different vehicle, and that's the tough part, finding out what they're from. You can see the tensioner and bracket below the A/C compressor, and the main snout bracket up top.

The only good news about that ad is that it shows the newer style Whipple compressor. Mine is the old autorotor style, which wasn't bad, but I think those are supposed to be better. If you really want it, maybe make an offer. If you need me to, I could probably take the brackets off and have a machine shop look at duplicating them. Might be kind of pricey though, they're aluminum, and the main snout one is two pieces that screw together around the snout of the compressor.
Also, that fuel pressure regulator is the one that came with the kit, but it's crap. I would count on replacing that with an Aeromotive unit. Mine was ~$120.
Mine ended up costing me around $2k when it was all said and done, with an initial purchase of the kit for $1500.
