You have an RSX right? That's what you got in your sig. That would be one I might actually consider getting an I/H/E and K-Pro on, only if the K20 was in a light hatch though (actually thought about doing that), in your heavy car I probably wouldn't bother. For a car like mine (ex civic coupe) it's a complete waste of money to go I/H/E.
Also what do you mean by good start? After I/H/E, unless you plan on going nitrous or S/C there ain't much else your going to do. Maybe cams? ITB's? More horsepower will proly need bigger exhaust than you got (nitrous or s/c), possibley better header if your going nitrous or s/c. ITB's you won't even use the intake you already bought.
Building an all motor setup and F/I setup would be different, sure the parts woudl work, but I'd specifically want a header and exhaust setup for F/I, not all motor.
