cool, i see...the cyclone intake is an interesting creature, it is sort of setup liek an integra gsr with the 2 runner setup, it is functional as long as you get the vacuum system setup right, it'll make some more low end torque, a factory USDM 1G intake is a little bit better as far as flow is concerned...but back on topic, a 1G (cyclone or USDM) throttle body, to my recollection, can be bored out to 64 mm, after that, you are looking for a new throttle body, hope this helps
