wrong, wrong, wrong...
The GT's 1ZZ has the potential for lift, it's basically the same block as the GTS.
If the guy swapped a GT motor into his GTS, he probably kept his GTS head and ECU, and put it on the GT block/tranny combo.
The GT block would have a lower compression ratio, as well as a longer stroke. My guess would be that it was rather torquey w/a few less ponies than the GTS (probably about 165 HP or so) Lift would engage, but wouldn't produce as much HP as it would with the 11.5-1 compression.
However, with those dished pistions & lower compression, it's the perfect combo to be used with Forced Induction or lots of nitrous.
1ZZ pistons will work in the 2ZZ, but will lower the compression substantialy.
Building a 1ZZ hybrid would be rather easy, compared to a honda VTEC hybrid.
