probably run a ls3 intake from a new camaro...seen em on ebay for less than $300
and finally some kinda of nitrous kit...dont know too much about it so hopefully someone can help me with that.

goal: 400to 450rwhp with 17-20mpg?? impossible???
If you're getting an LS3 intake, you have to run the L92 or LS3 rectangle port heads. Look at spending AT LEAST another 600 on those. The TR224 cam isn't a great choice for L92s either. What gears does this thing have? You're going to struggle to get 17-20 mixed. Highway is possible.
