This is the car I mentioned with the nutty build for a racecar in Japan:

290PS, still very respectable for a N/A EJ20. And plenty past what the other guys are talking about. It is possible with the displacement. Honda K20 guys do it, and Mazda MZR 2.0L have done 300HP. And this engine starts at 200PS @ 7000RPM, stock.
Stock engines are usually heavily choked. It doesn't matter that it is the highest N/A output, they have to meet strict emissions and there is always room for improvement. The question remains how much. But I am optimistic that there is room just in a 93 octane tune.
