What mods does the car have done to it? There aren't any TB's off other engines that will just bolt right up. You'll have to buy an adapter plate to make the conversion. ZZP sells an adapter plate for a Northstar TB, which is the same diameter as the LS1, but probably easier and cheaper to find. Just make sure you get one from a 2000+ year with 3 mounting bolts and not 4.

TB should be put on the back burner till you invest in an intercooler or a cam.

I'm with Matt, there's no point in wasting money on mods that won't benefit you right now.
A throttle body is something you don't need until you're outflowing stock.

I agree with the other two. For what you have, I'd say scrap the TB idea and go for a set of headers.

LS1 TB Setup wouldn't be cheap.
You'd need an adapter plate for one, an external LQ4/LS1/SLP 85mm MAF Sensor, LS1 TPS/IAC, You'd need to cut off the throttle bracket, flip it over...and weld it on backwards..then in order for it to be efficient enough, it would need to be tuned for it, along with the blower being port matched on the inlet side to benefit fully from it. On a stock pulley...it would probably go more harm than good...you wouldn't need a LS1 TB setup until sub 3.25" pulley sizes...full size intercooler or cam...
