RGM in South Africa got 404 hp at the wheels of my 2.0l S2000 with a bolt on vortex supercharger The rest of the world got the 2.2l version I think.
Other than the charger ... the setup is stock. Only other mod I did were the brakes, for Obvious reasons
Forgot to mention that I've done 16000 kms since then ( +-10 000 miles ) Trouble free
