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.

3 bar.

3 bar pump gas?? Im sure that wont be safe.

I think, and this is just a hunch, he was using SARCASM

EDIT: but reallly good combo by the way, great results just dont use 3 BAR...

haha, SARCASM again? twice in a row seems too unlikely, this must be an actual /proven answer

ye, sorry mate, to be honest there is no right answer.

it comes down to are you willing "to risk it to get the biscuit".

My car makes 270hp @16.5PSI, I could wind it up for 300+hp and risk drastically shortening the life of the internals.

Its the same for you. If you have an awesome combo to start with do you really want to blow it for the extra ponies?

Check out the "new fancy perf thread" few guys running some serious boost on the EJ207's

Is your block a jdm ej207? If so you have hypershit pistons and i wouldn't be putting much more power through it to be honest. Have you thought about building a stroker motor?
