    2.5'' isn't too big mate, it's an absolute must if you're wanting to make decent power! Any smaller will be a restriction to flow.

    I must say that core looks very small though, due to the hot nature of ko4 hybrids I personally don't think that'll be big enough to keep charge temps in check, certainly not without WMI.

    What's your intended power goal?

    I'd try and get a deeper core in there mate.

    If you're happy to stop at 300bhp then you should be OK without WMI, mine has a MASSIVE intercooler, and will happily produce 335bhp without WMI. Using the WMI allows it to be safely taken futher.

    Heat, and EGT's are the enemy with a ko4 hybrid, but it's well worth it if you can control temps, as the power you get it near instant, you touch the throttle, and it just goes!
