    Right now Im running a T3/T4 Hybrid.. As for power goal I don't really have a specific hp goal. Id like enough power to run low 12s or break into the 11's. Roughly how much power would that take?

    Careful with that "built" ITR head. If it has all motor cams in it you will have some overlap. This is undesirable in any forced induction application.

    Not useless, nessicarly.

    It just means that both the exhaust and intake valves are open, so boost can travel right through into the exhaust until the exhaust valves close.

    gsr cams are considered the best oem honda cam for boost. I've seen reports of people gaining 20whp just by tuning the cam angle of gsr cams on the dyno.
