kay...ill try to answer what i know...

the H serie engines are DOHC vtec...which has double cam..
urs is the F series...single cam..vtec or not..it depends on which trim model u have...

if youre seriously want to get into the 14s without any swaps...u might want to consider force induction...
bolt ons alone wont do it...

the header will most likely help you with the torque...

almost any catback systems are very similar...the exhaust is what makes each sound different...most have minimal gain on stock cars...

aftermarket pullies are lighter...helps gain a few...
