Lightweight pulleys do not cause significant friction reduction...and flywheel horsepower is after all the engine's mechanical friction is accounted for. The car does not lose 15% to the wheels, it loses ~10% and then the dyno sees another missing 5% because the rotating mass is absorbing kinetic energy as it accelerates, and the 1% or so of energy that the tire is absorbing.

The 2ZZ-GE has .2L less displacement, but also revs higher to make up for it. The difference in revs is big enough that the FA pulls in about the same amount of air at peak power.

Anyways, I highly doubt you can hit 300 without swapped internals. Most I'd bet on is being able to match 2ZZ numbers.
