5.3 Engine-> LS1 Intake->Need different TB?

It's interesting. I've read over and over how that LS6 will increase the hp by 10-15. Any idea why it wouldn't make much difference on this engine?
I just went onto eBay, and found the adapters. They are $60-70. Seems like maybe that could be a good down payment on a polished TB from S&P, or a better TB (of course I don't know what that would be...I'm so green about LS).
I found these injector spacers on eBay, and he indicate he does have LQ4 spacers. I presume LQ4 spacers is what I need. Correct?
Maybe I'd be better off getting a complete intake, with all the other stuff.
BTW...you're the second person to reference a $30 LS1 intake...but every one I've seen on eBay for an LS1 has ended up at over $100. There are two on there now for under $100, but bidding has just started. One there with TB, Injectors, and rail for $300.
