Worth doing with my set-up?

KO4 w/ 380cc injectors, PWR FMIC nad 3" Turbo back exhaust, custom GIAC chip.

Any input appreciated.

Although I might be slightly biased.

what kind of gains can be achieved with a new set of cams, I heard it is minimal for our engines.

Wont see much gains till you replace the turbo with a larger one that can take advantage of what the cams do. I would think the cams might give the K04 setup a slight gain in bottom end tq, but that might end up hurting the top end power since at that point the k04 just cant keep up the flow. With a price tag of about $800 its a very small gain for the cost.

330 injectors even w/5 bar FPR doesnt seem enough to move the powerband up, and the K04 runs out well before 5500-6500 rpm where the cams have an effect. I would stay with stock until you upgrade everything else up.
You may move the powerband to a place where your supporting cast cant cut it.

what about with a GT28RS set up?

and hold a set boost to redline. Just have to understand that this type of mod wont give you big gains for the cost.

but the K04 peters out at the top-end.

So you may gain some power at the top-end, but probably lose more down-low than you gain at the top.

I'm sure with an adjustable cam gear, you can adjust the power band back, but if you do that, what's the point of getting the cams in the first place? Maybe just try the adjustable cam gear first and see what happens.

As Mike said, the cost per HP gain is pretty high in this case, and the money is better spent on other things (i.e. big turbo)

and only after a bigger turbo is done.
