the differences in power of the 1zz and the 2zz don't seem that significant, you could attempt to swap motors if you really wanted, but I don't see a reason.
140 hp compared to 180 hp isn't that bad, you won't get as much power out of it, but boosting might help.

I personally don't see why you'd want to pump more power out with these gas prices
but good luck and welcome
