short, simple, i like it. So who thinks 15PSI would be enough to push me to 300HP? I am guessing since I saw a 256HP D16 with 16PSI 9:1 compression pistons. And the B18 is 0.2L bigger. I wonder if the stock SRT4 turbo will fit. That will boost up to 15PSI stock and with a stage 1 kit I think they get them up to 17PSI and stage 2 like 20PSI. Obviously your not getting a bigger turbo with the different stages I think just new BOV and stuff. I figure find a turbo of a car thats turbo from the factory and try and use that, it should be much cheaper.
