There is no point buying 440cc injectors only to replace them later with 1000cc same with the turbo. A nice turbo sized for his current goal probably would not serve him best at significantly higher power levels. Same with a clutch, etc etc.
If he thinks he will want more than he should just set out to build to that point now, Rather than spending the money twice.
But with a 50 trim, or 57 trim t3/t04E setup, at low boost, it will provide those levels, and at higher boosts, it can reach 350-450 hp. 620cc injectors are good from around 250-400 hp, assuming you have a proper way of regulating fuel pressure.
I agree, rods/pistons aren't all there is to it. Hence why, in my original post, I said, if he has the experience/knowledge/ability to do engine work, source out the work needed, and get the parts. Otherwise, give a professional a specific goal, specific information, and let them handle it. They'll tell you what you can pump it to with those parts, before you need to upgrade again.
But, anyways.
