I have a 95 3sgte that will be going into my car very soon and I was wondering what the max boost pressure is that the engine can run on. I though I saw somewhere that you can run the engine on 15psi comfortably and that is the max boost, but maybe I am wrong. Also is it safe to run the engine on 93 octane or do you have to use 103?

No I'm not speaking RON. Here in the U.S. we use PON which is the average of RON & MON.
Here in the northeast, 93 is the highest available octane, 87 is the lowest. You have to adjust your thinking to a different set of standards. -------------------- |

You have to adjust your thinking to a different set of standards. ah ok, not sure how that works then!! LOL... you take the RON rating, add it to the MON and divide by two.  Really though, US 93 octane is equivalent to something around 97-101 octane by the straight RON. I don't know the exact conversion. I run a JDM '95 ST205 motor on US 91 octane fuel (highest available in California) and only have minor problems with hesitation from low octane (even at 17lbs of boost). The knock sensor does a pretty good job of pulling timing when necessary and I've never gone into safe mode from detonation (nor heard any). -Charlie -------------------- 2003 Subaru WRX Wagon
