745 D24T looking for a little more power

[Volvoguru850r]

What would you guys recommend? I don't wanna decrease longevity of the engine, just a little more get up and go. It runs pretty solid as it is. Should i make some adjustments to the injection pump? Bigger injectors? I plan on added a IC here in the next month or so. I was wondering if you guys do away with the turbo intake and go with a d24 n/a intake...just seems to me from the looks of things that the n/a intake would be more suitable...let me know your thoughts!!
