ITBs on a Turbo app will have response just as good as an N/A app
i think you're wondering if ITB's on a KA-T will make more power than the stock manifold
it'll make more power if it's tuned to make more power, which it more than likely will be, but it will also allow you to run a larger plenum, which isn't necessarily beneficial...
anywho, the RB26 has ITB's, so if thats any indication of itbs and turbo excellence....
additionally ITBs should help get equal cylinder filling where as a single throttle body and a plenum will tend to disitribute more air to the first cyl, then the sec, then the third then the forth. its a small effect, but it just makes tuning alittle more difficult when number one is leaner than number 4
any change over the 20+ inch intake manifold will be an improvement, because 20 inch runners are trying to make power in the 3000 rpm range
