Please consider: The 2ZZ-GE is probably the best N/A motor Toyota have ever produced. Over 100hp per liter! It would be an improvement over the 4A-GE 20valve, and I think a little more advanced than the 3S-GE beams motor. It would be equivelent to the Honda S2000 motor and things like that, in terms of power per liter for a N/A motor. The "VVTi-L" badge is a bit missleading, and not realy the best name for the system. The cam/rocker setup is mostly copied from the Honda VTEC system where you have two seperate cam profiles on each cam, very different to all other Toyota "VVTi" systems. To me, the difference in duration is more important than the difference in lift, but the 2ZZ-GE has both with the seperate cam profile. The 3S-GE Beams motor is "duel VVT" where each cam can be rotated to change the lobe center and overlap, but the duration is still fixed. In addition to the VTEC system, the 2ZZ-GE also has the now common VVTi setup where the intake cam can be rotated also to change lobe center angle and overlap.
Generaly speaking, if keeping the engine N/A there is not much more you can do to the 2ZZ-GE. It already has high compression, light flywheel, ok exhaust system. I havn't fully resurched everything, but on inspection most of these parts look ok. I doubt a different air filter would make any difference, and slightly different air ducting may, but I doubt it. To get more power you really have to lift the rev limit a bit more and get different camshafts with even more duration. So its new camshafts and computer, and tuning.
Stock they have about 180hp or a tad more. Modifyed with big cams I would expect over 200hp wouldn't be too hard. (Who makes cams for these?) Consider that people can get about 200hp out of a 1.6 4A-GE with big cams, about 320/305 degrees I guess. Also consider they can only get 240hp out of a Formula Atlantic motor, so you will be coming up against a big wall of money getting towards those figures.
Or a supercharger/turbo kit... The compression will need to be lowered, chipped or different computer...
