200kw atw on a EJ205 is achievable but will decrease the life of the motor.

To do it you will need to run sti injectors, bigger fuel pump, 1.3bar...and a VF35/34/TD05-16G (a 34/35 if you want compressor surge, TD05-16G if you want full boost by 3000rpm) : P

motor will be good for about 100,000kms then might need a rebuild.
