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.

i did state that i was going to swap internals, new valves,springs,retainers,cams, lighter pistons and rods, change the redline to 8500, then i would be able to rev just as much as my current car...
the 2zz-ge was limited by its head design and intake manifold design , it didnt flow like a k20, the most anyone ever got out of a 2zz-ge Na was about 250 WHP, k20 got about 300+ whp
if the head does flow better, which i imagine it does because of the torque numbers, we will see better gains than the 2zz-ge
if you ask anyone who has seriously tinkered with a 2zz-ge would know that, its not the best flowing engine out there, DDprefomanceresearch made a new intake manifold that yielded some pretty crazy numbers, i think it was like 30hp untuned and 50hp with a tune
