I would also like to add that the Toyota Racing Series are based on the OG 2013 2.0l engine released here in australia, no internals, just bolt ons and a new ECU - these produce 240hp (179kw) at the crank, up from 197hp.
Thats a gain of 43hp. I cant find the performance at the wheels, but I'd assume it was around 200hp or more.
Is it practical for the street with the noise of straight pipes? probably not, but there you go. I'd imagine there would be a little more power there if the teams were allowed tweak it (its a locked ECU).
Look at this lineup
