Admittedly I know next to nothing about the fwd cars, but have you checked the LS4 Performance subsection on here? That's where I'd look. On the first page alone I saw threads about LS6 intake manifold swaps, longtubes, and trans coolers.

First off, welcome!

Yup, check out the LS4 section for some better answers.

The basics can be applied to any engine, good exhaust, intake etc. For more specific info on the LS4 check out the LS4 section.
