This Toyota 3-cylinder already makes more HP/L than those other engines do tuned, it makes more HP/L than a Focus RS or Civic Type R.
Will it have a flash tune that offers >5% improvement within a year? Absolutely. Will it push 300whp reliably without significant investment? I seriously doubt it. Can you build it into a monster with enough time and money, sure but with that kind of fantasy everything is a $100k check from being faster than a hypercar.
It's 167HP/L, the Ferrari 3.9L V8 in the outgoing 488 is 169HP/L. Toyota can't break physics. It is a very short list of cars that make more power/displacement than this car with a factory warranty, even shorter if you cut out cars that are >$100k.
It's a totally safe bet that there isn't much headroom left in this engine.

If "there wasn't much room left," it wouldn't pass emissions. That's why Europe cannot use the new engine in the new twins. The sonic comes with 138 hp. The fiat with 160. Getting 200 hp out of that is impressive. 167 hp/l means nothing after boost. f1 used to get near 1500 hp out of 1.5l turbos in the 80's. The GR4 engine will be rated at 257 hp. We'll see what it really makes. Thinking it cannot make more is just silly. You are completely underrating European emissions and how much they have to screw with the tunes on these cars to pass that crap.
