I spoke to the main guy a ST Hitec in Auckland NZ (Soichi Tate hes ex nissan japan engine development) he said you could get to 210kw approx at 1.1 bar but the injectors would be near the max on the duty cycle, thats with FMIC, intake, turbo back exhaust, better fuel pump + reg, stock turbo with EBC and retuned ECU. thats on the Spec R manual 480cc injectors not the Spec R Auto ones (purple) which are something like 380cc

Ok... Is the 210kw.. engine hp or Wheel hp.. ..?? sounds like hp on wheels.. if it's engine I'll have to lower the boost..hehe
because when we boost 0,95 bar it's +- 300 hp.. and thats more then 210 kw..?

about 200rwkw is about the max. (give or take depending on the conditions and the dyno)
