Hey guys im a new member on here from New Zealand, im running a ej207 version 7 spec c block with v6 sti heads in my version 6 gc8 sti. At the moment im running around 270kws using a garrett gt3082r, link g4 ecu, 875cc top feed injectors, walbro fuel pump and other supporting mods. Im running 1.7 bar boost max on 98 octane fuel and ran a best of 11.7 at 198.24km/h.......I wanted to know whats the max boost i can run on this motor safely on 98 pump fuel and how much power is safe on it? I want to run around 1.8 bar and make atleast 300kw after changing stock cams to 264 kelfords also whats a safe rev limit on them? My afr is around 11.5 to 11.7 at the moment.
