    If you have a stock engine I suggest making sure the ecu chipper set's your redline to around 8800, because at 9k you get valve float.

    VTEC, have it set around 5300.

    Would I get valve float at 9k in an JDM Integra type r motor?

    i would agree w/ the 8800 rev limiter.
    as far as the VTEC point... 5300-5500 would probably be just fine.
    do you plan on running a VAFC or other type of controller at all eventually?

    it will def. help and not hurt. then you can fiddle w/ the VTEC x over and find one that is suitable

    Vtec should be placed where the 2 torque curves cross. (ie first cam and second cam)

    set the vtec crossover to 8K and make a dyno run.
    then set it to 3K and make a dyno run

    wherever the 2 curves meet will net you the most area under the TQ curve.

    the stock itr ecu makes vtec kick in at 5700. Should I leave it at this, or engage sooner, like at 5400?
