Re: d15b2 power?
one thing all noobs should realize, n/a D is gonna be torqueless, unless you really get crazy w/ it. the reason people spend so much time w/ D's is because they are cheap, parts are abundant, and alot of parts are interchangeable. if you are serious about making power and have any sort of budget absolutely forget N/A D. there are few that have even seen 150whp n/a, and lets not talk about the tq numbers. all in all, D's are meant for MPG or boost. w/ a good setup both MPG and fun factor will be perfect for a DD, and when you decide its not fun anymore, build a block and turn up the boost, either way, you will still be under the cost of even a B16 gen II swap, and if you blow the D, who cares, spend $600 at the most and have a low mileage motor shipped to your door.

as for HP V Trouque.
Increase HP = increase tourq, Increase tourq = Increase HP.
As for you saying a D series needs alot of RPMS well alot of that depends on the setup, again, each engine is diffrent which yeilds diffrent power.
as for FI, thats a diffrent ball game.
You can put a turbo onto any engine, and it will boost and be more powerful, However N/a is more like art. YOu have to paint the drawing, and imagine it in your head.
