otherwise grab an ej207 oil pump and keep upping the revs on whichever motor you choose and see where the valvetrain becomes limited.
electric power steering
port intake manifold & throttle body
you could always add an n2o 50 shot
Thus far the only numbers in that region have been on E85. On pump there hasn't been a TRUE 200whp claim.
