Danz and I had this discussion many months ago. We both agreed that the s/c would benefit the 2zz greater as it fills the 'lag gap'. It's clutch activated, and you aren't running a stupidliy large amount of boost that spools up @ 3,000rpm odd. If you want the 2zz to go quicker, while still being sane...go s/c. If you want turbo? I reckon actually get a Supra or a REX or something. Something that is factory turbo'd.
